Employee salaries, rental space, machinery, logistics, packaging and travel costs are a few significant factors impacting the budget of an office. Making profits in business is not easy especially when you are trying to break-even and increase profitability. However, often while trying to cut costs, we turn a blind eye to the electricity bills.
Expense on electricity is substantial and can add up to the running costs of a business. The need to have a sustainable plan regarding the cost is beneficial to the financial health of an enterprise. By carefully assessing the energy expenses one can substantially reduce the operating costs. With electricity forming a major portion of expenditure, it is imperative that we save in this sphere.
So, here are five effective ways to reduce your office electricity bills.
1. Upgrade to Energy Saving devices
Simple changes can go a long way in helping you save on electricity bills. Instead of continuing the use of conventional methods which require much energy, consider investing in energy efficient devices. Upgrading to new appliances might cost more initially, but they will help you cut electricity costs over the next few years. With an upgrade, you will also get a more efficient, faster and productive product. You can also go about hiring an energy audit company for your office; they will analyze your practices and provide ways to reduce your energy needs.
2. Use LED Lighting
Switching to energy efficient lighting by using LEDs instead of the incandescent light bulbs is the latest trend in the commercial and industrial world. The up-down feature helps in distributing light uniformly. The figures suggest that 33% up and 66% downward light distribution give a spacious and distinctive look to the workspaces. Also, factors like low power and high efficacy of LEDs contribute to up to 50% of energy savings.
In fact, LEDs are best for energy saving and ensure energy efficient lighting. Additionally, they can easily be recycled. LEDs have no hazardous chemicals and last much longer, reducing the replacement costs substantially. LEDs also use lesser energy in comparison to traditional bulbs, burn brighter and significantly improve the aesthetics of the room.
The use of LED light has a number of advantages that we have already mentioned in our article “5 benefits of LED technology from incandescent lighting“, but what I have not specified is that they can be easily recycled due to the fact that they do not have dangerous chemicals, lasts longer, so you can recover your investment in a short time.
3. Use Electricity Prudently
Technology is both a boon and a bane. It has affected our choices and has also made us careless towards our environment. On a hot day, it is common to use the air conditioner for a long time at work places, to a point where it is unjustifiable. Instead, you should use the HVAC prudently to cut the electricity bills. The human body is made to adjust to different environmental surroundings, and one should let the body run its course. Another practice to adopt is to turn the fan on and increase the temperature of the HVACs.
It will reduce your bills, and the employees will appreciate a more neutral temperature in the office, making them less vulnerable to common cold or fever.
4. Ensure Switching Off Electronic Devices When Not in Use
This technological age has brought significant changes to the personal lifestyle, making people addicted to their devices. One of the major causes for the rise in electricity bills is wastage of energy. It is always a better idea to unplug electronic appliances when they are not in use. Not following this practice at an office, adds to the huge cost as the number of electronic devices are far more in number, than at homes. Monitoring the use, and implementing vigilant policies will result in electricity savings. This will also provide more shelf life to the devices and further cut down costs in the long run.
5. Use Intelligent Lighting Controls
By using intelligent lighting controls, a business can reduce their office bills. A high-performance daylight dimming sensor detects the amount of sufficient daylight and switches off luminaires when not required.
Maximum use of sunlight can be facilitated by installing larger windows. This will essentially provide a more natural aura. While bigger windows will draw in more light, during the winter season, it will also reduce the electricity bills. One can always install sturdy blinds to keep the office cooler in the summer season.
Forget classic chandeliers and lamp shades. This year, it’s all about modular, minimalist and shape-changing designs. Thanks to LEDs and other new technology, designers are now able to change the shapes and even the uses of light fixtures, and the exhibitors at this year’s fair ran with their newfound freedom. Have you ever wanted to play with your lamp or change it to suit your mood? Now you can. Get ready for modern light pillars, customizable lamps and minimalist chandeliers.
Harry H by Carlotta de Bevilacqua for Artemide
1. Technology Meets Craft
“Lamps are not just shapes. Light is a basic human need, just like air and water. Technology is what brings us light at home, so we shouldn’t be afraid of it. Instead, we need a vision for driving lighting technology forward. In doing this, we should always have our human needs, and nothing else, in mind,” says Carlotta de Bevilacqua, architect and vice president of Italian company Artemide.
She designed the hybrid light fixture Harry H as a kind of manifesto, connecting technology and traditional craft. It combines hand blown glass with OLED and LED lights. The two light sources can be controlled separately to precisely define the quality of the light the lamp emits.
U-Light by Timo Ripatti for Axo Light
2. Going Graphic
Pure lines, signs hanging from the ceiling, tiny waves on the wall — designers are transforming classic lamps into minimalist sculptures.
Thanks to LED technology, lamps can now have a light source anywhere, even bent around a curve. For example, U-Light, by Finnish designer Timo Ripatti for Axo Light, incorporates an LED into a series of circular aluminum frames.
Compendium Circle by Daniel Rybakken for Luceplan
Norwegian designer Daniel Rybakken also used circles in the Compendium collection he designed for Luceplan. LED technology permits the emission of both focused light, when pointed downward, and diffused light, when aimed upward. This chandelier is customizable and can be built from up to three rings of varying diameter, so you can decide on the final shape of your minimalist chandelier.
Yanzi by Neri & Hu for Artemide
Yanzi, designed by Chinese duo Neri & Hu for Artemide, is a lightweight lamp that can either be suspended or used as a floor lamp. Its clean design invokes branches, with movable swallows sitting on top. The lamp makes it possible to create a kind of poetic domestic landscape.
3. Pillars of Light
Heliacal, by Dutch design studio Os & Oos for FontanaArte
On the other end of the minimalist spectrum, floor lamps are becoming bigger and bigger, iconic — or ironic — and eye-catching. Heliacal, by Dutch design studio Os & Oos for FontanaArte, is a good example. Inspired by the way light changes all day long between sunrise and sunset, it has polarized glass discs that can be rotated, blocking the light or allowing thin beams to escape. This introduces movement and gradation, from a dawn effect to an eclipse, into the design. It is a magical modern totem.
Pinecone by Paola Navone for FontanaArte
Originally designed to be a table lamp or a suspended fixture, Paola Navone’s Pinecone this year grew to be a floor lamp. It uses the ancient technique of caged blown glass, which creates the impression of glass — and light — trying to break out from its restraints.
4. Lamps That Are More Than Light
With new technology making design more flexible, lamps now do more than just dispense light. A good example is Diade, by Monica Armani for Luceplan, which integrates acoustic solutions that absorb noise (for example, over a table or in an office) and thus promote psychophysical well-being. It can also be folded (see the next picture) to separate the space below it.
5. Lamps as Playful Objects
Gaku by Nendo for Flos
Gaku, designed by Japanese studio Nendo for Flos, is a wood-framed, do-it-yourself decorating set that happens to also be a table light. You can play with different elements to create your own lamp. The light source can be suspended from a cable that comes out of the frame. There is also a wireless version – another current trend -in which the lamp can be recharged through induction plates.
Graffiti by Kazuhiro Yamanaka for Pallucco
Another object by this Japanese designer is Graffiti, a light sculpture with metal rods you can move and play with, drawing your own domestic light graffiti and easily creating your own art installation.
Amisol by Daniel Rybakken for Luceplan
Daniel Rybakken’s Amisol takes advantage of large dimensions. Like Collapsible Moon, it is a diffused version of a photography bank light. A translucent white film or a metallic mirror membrane is stretched inside a circular aluminum frame to create diffused light. The lamps can be pointed in any direction.
Mesh by Francisco Gomez Paz for Luceplan
6. The Second (Lighter) Life of Chandeliers
What happens when designers start using LEDs in chandeliers? Design becomes fragile and poetic. Mesh, designed by Francisco Gomez Paz for Luceplan, is a light structure composed of a network of metal cables, with LEDs positioned at the intersections. It’s available with 96 light points or as a smaller suspension lamp with 48 LEDs.
Verticale by Ronan & Erwan Bouroullec for Flos
“Modular” is the keyword for many of the lamps presented at Euroluce 2017. Verticale, by the Bouroullec brothers of France, is a set of suspension lights of variable length that can be put together in various geometric configurations, such as a triangle or a pentagon. Their anodized aluminum frame reflects the light source.
Alysoid by Ryosuke Fukusada for Axo Light
Alysoid, by Japanese designer Ryosuke Fukusada for Axo Light, is composed of necklace-like draped chains. It was inspired by architecture: The alysoid was a beloved geometric form of renowned Spanish architect Antoni Gaudí.
Leaf by Matteo Zorzenoni for MM Lampadari
The new shapes of chandeliers may be different from the classic versions, but they are just as eye-catching. In Leaf, Italian designer Matteo Zorzenoni tried to mix past and future. The suspended light fixture is available in brass or copper.

Using solar LED lighting outdoors can be a lifesaver when outdoor outlets are not available. But do solar-powered LED lights really work? How do they measure up to hardwired electric lights? And what if your yard is shady or you live somewhere that rarely sees the sun? Here’s the full scoop on choosing and using solar-powered lights in your yard.
SOLAR LED LIGHTING
How solar LED lighting works
Photovoltaic cells absorb sunlight during the day to charge the batteries, which then light the bulb at night. Because solar lights are powered by the sun, they must be placed in an area that receives full sun — ideally eight or more hours per day.
What if you don’t have direct sun?
If you are putting solar LED lights in your desert yard in Tucson or Palm Springs, they are sure to operate at maximum strength — but what if you live in Seattle or simply have a heavily shaded yard? It’s not quite as simple, but you can still have solar-powered LED lights, even in a fully shaded area. A solar or landscape lighting pro can help position a remote photovoltaic panel on your roof or in a sunnier area of your yard, which can then be wired to the lights in the shady area.
If there simply isn’t much sunlight to be gathered, even on the roof (for example, you live somewhere like Seattle or Portland), the solar lights will still work, but they won’t shine as brightly or for as long each evening.
Types of Solar LED Lights
Solar path LED lights
These are small solar LED lights on stakes, which can be pushed into the ground alongside a walkway to softly illuminate the path at night. They are not as bright as electric path lights, so plan to use more (up to twice as many) to light your path with roughly the same glow as electric.
Where to use solar path LED lights
Solar path LED lights are ideal for illuminating walkways far from exterior outlets, and can provide an enchanting glow along winding garden paths.
Ambient and decorative solar LED lights
Decorative solar LED lights, including colourful blown glass, decorative lanterns and string lights, are not as bright as solar path LED lights. However, used in multiples or alongside path LED lights and LED spotlights, they can provide a warm ambient glow.
Where to use ambient solar LED lights
Place a few windblown glass solar LED lights on stakes in your garden beds for soft landscape lighting. Or hang solar string LED lights, like the charming mason jar lights shown here, over an outdoor dining table for a welcoming touch at your next gathering.
A solar table lamp, like the one shown here, can be a welcome (and unexpected) touch in an outdoor seating area.
Solar-powered LED spotlights
The brightest solar LED lights available are called task lights or spotlights, and the best ones can provide light that’s roughly equivalent to a 40-watt incandescent bulb. That is still not as bright as a typical outdoor spotlight, so you may want to double or triple up in areas where you want bright, direct light.
Where to use solar LED spotlights
Motion-sensing solar LED spotlights can be used near doors and in the driveway. Spotlights can also be placed in the garden, with the beam of light directed at a tree or another landscape feature.
Pay attention to the hue
Since most solar-powered lights today use LED bulbs, the light they emit is bright white. If you want the look of incandescent bulbs, look for solar lights with tinted covers — they may be labeled “amber” or “soft white.”
You get what you pay for
The brightness of a solar LED light depends on the brightness of the sun and the amount of daylight it is exposed to — but it also depends on the quality of the photovoltaic cells and the size of the LED bulb. Higher-quality photovoltaic cells and larger LED bulbs tend to cost more, so to a certain extent, the higher-priced solar lights do tend to shine more brightly.

Why choose LED Lighting in Agriculture?
Wherever you use lighting in your business there is potential to save money on your electricity bills and cut your carbon footprint through low energy lighting.
There are a variety of low energy lights to choose from including T5 energy efficient fluorescent lights and LED lights. Low energy lighting can reduce your energy consumption by up to 80% and fitting the lights is as simple as changing a light bulb!
The benefits of using LED Lighting in Agriculture
The use of LED lighting in agriculture is becoming increasingly widespread. LED lighting uses significantly less energy than the traditional fluorescent fittings used throughout the agricultural industry.
Research has found that LED lighting is not only suitable for horticulture and livestock but has even been attributed to increased production! This is thought to be due to the fact that LEDs offer a more ‘natural’ light than incandescent or fluorescent lights.
Dairy – studies by the Oklahoma State University on the use of LEDs in dairy sheds demonstrated that when fluorescent lights were swapped for LEDs, dairy production actually increased by 6%!
LEDs achieve the greatest energy savings where they are used as replacement for energy-intensive fittings like halogen bulbs. However, even the replacement of fluorescent strip lights (commonly found on farms) with LEDs can achieve 70% energy savings and a payback period of less than three years.
Horticulture – LEDs can stimulate plant growth by up to 40%. According to Hort Science, LEDs are the first light source to allow spectral control so that wavelengths can be matched to plant photoreceptors and increase production.
Since LEDs are solid-state they can easily be integrated with digital systems that simulate sunrise and sunset. Although LED technology is not new to the horticultural industry (first experiments began in the 1980s) the quality of products on the market today offer a light quality and energy savings like never before!

Philips Lighting cracks code of shopper behavior proving how colored lighting boosts supermarket sales
Pilot study in Globus supermarket in Germany used colored LED lighting to increase sales by 6% and traffic at the store’s promotional area by 15%
Düsseldorf, Germany – Philips Lighting and Globus, a major grocery retailer in Germany, have measured the positive effects of lighting in a joint research project. In collaboration with German Research Center for Artificial Intelligence DFKI and EIT Digital, a series of experiments were conducted at the Globus supermarket in Saarbrücken to study the impact of different combinations of colored lighting on sales and customer behavior. The results showed that using colored uplights together with Philips StoreWise lighting system helped increase sales while enabling energy savings of up to 75% compared to conventional lighting.
For the experiment, researchers spent two months testing different lighting conditions at the supermarket’s 180m2 promotional display area that was equipped with Philips StoreWise and Philips LED lighting. Three settings were tested: the store’s uniform overhead lighting, regular spotlights and a combination of spotlights with pastel colored uplights.
The study showed that the most effective setting for enticing shoppers was using spotlights with pastel colored uplights that led to a 6% increase in sales of goods from this promotional area. The same combination of colored lights created the best stopping power for this promotional area and increased customer visits by 15%, compared to the standard store lighting. When conventional lighting was replaced by spotlights alone, 7% more customer visits occurred.
“Adding soft pastel colors to highlight products is a potential game-changer for the retail industry. For the first time research has shown that different lighting conditions can affect shopper behavior and drive increased store revenues,” said Gonneke Gros, Segment Lead Food and Large Retail, Philips Lighting. “With new lighting systems like Philips StoreWise and Philips’ indoor positioning system, we anticipate retailers to analyze sales and traffic data within their store in real-time and adjust the lighting conditions to optimize sales.”
Retailers have traditionally lit stores using uniform, white, overhead lighting. The research showed that the 58 spotlights used in the experiment strengthened the appearance of products by increasing contrast. Adding colored uplighting (aimed at the ceiling) as well, helped differentiate the promotional zone and make it more visible from far away.
Norbert Scheller, Store Manager at Globus supermarket in Saarbrücken commented: “As a retailer, to stay ahead of the competition, you have to create a multi-sensory environment and a ‘wow-factor’ in your stores. Working with Philips Lighting has helped us realize the immense potential lighting can have and we have successfully been able to create triggers to direct our customers to promotional areas in our store and to inspire them in new ways.”
This new study reaffirms earlier findings from Philips Lighting research showing that soft pastel colors make customers feel happier and more comfortable when shopping, while saturated colors increase stress levels.
How the LED experiment to boost sales was put into practice
The research at Globus supermarket in Saarbrücken, Germany, was done in collaboration with German Research Center for Artificial Intelligence (DFKI) and European Institute of Innovation and Technology (EIT). During two months, different lighting conditions were tested at the store’s 180m2 promotional area. Sensors in the ceiling and in 300 shopping trolleys were used for recording the number of visitors and the time they spent within this zone compared to the rest of the store. The data was also analyzed against sales figures, examining the number of products bought from within this specially-lit area.
For the experiment, Philips StoreWise, an intuitive lighting system for retailers, was used in combination with Philips’ LED lighting. Each light point in this lighting system could be independently controlled via the Philips StoreWise web app and be individually adjusted for color, brightness and saturation. This allowed store managers to fine-tune the lighting conditions at the tap of smartphone, tablet or computer whenever they wanted. Three lighting scenes were applied: (1) uniform lighting to mimic regular lighting (baseline for research), (2) spotlights to illuminate and make promotions stand out using light and shadow, (3) uplights with soft pastel colors to create a distinct atmosphere and to play to the moods of the shoppers.
Following the successful pilot, Globus supermarket has decided to leave the Philips StoreWise and LED lighting installation in place at its store in Saarbrücken.
Conclusion – experiment shows how LED can be used to boost your sales!
Either you work in fashion, furniture or home appliance showrooms, it’s high time you tell your manager to use colored LED Lighting to boost the sales. Maybe it would be the best idea of the year at your company and it will significantly boost the sales – are you ready for that?

At the upcoming Strategies in Light 2017 conference which will take place from February 28 to March 2 at Anaheim, CA in the track entitled “Technology Innovation to Support Market Growth,” a session will be devoted to the topic “Light Source Evolution and the Future of Lighting.” The lead speaker in this session will be Paul Rudy, PhD, co-founder and SVP of business development at SoraaLaser, whose presentation is entitled “Laser Light Sources for Specialty Illumination Applications.” Rudy has worked in the field of photonics for 20 years and has extensive general management, technical product marketing, and product management experience.
Recently, SIL co-chair Bob Steele interviewed Paul Rudy regarding the subject of laser-based light sources.
The interview, presented as you also can read in on its original source, Leadmagazine.com:
Bob Steele: InGaN [indium gallium nitride] diode lasers have been around for a long time, and are widely used in consumer electronics products such as Blu-ray players. Why are they only now being considered for lighting?
Paul Rudy: In recent years, a more advanced type of visible laser diode technology has been developed, largely at UC Santa Barbara, based on a material known as semipolar GaN. The use of semipolar GaN results in the elimination of internal electrostatic fields, and maximum overlap between electrons and holes. Diode lasers based on this material have a 3-5X higher gain compared to more conventional c-plane InGaN laser diodes. This high gain, along with design freedom such as aluminum-free structures, enables higher power and higher efficiency InGaN lasers. From the applications perspective, high-power blue lasers have seen increasing use in the area of projection displays, which has driven production volumes in the industry, along with advancements in efficiency and cost.
Steele: What kind of performance is achieved with this approach?
Rudy: Wall plug efficiencies of up to 40% have recently been reported, up from 15% in 2005. Optical power outputs of 6W have also been reported. The main thing to realize here is that, unlike InGaN LEDs, these diode lasers do not suffer from “droop” (the roll-off of efficiency at higher drive currents). Therefore, high wall plug efficiencies can be achieved at high power outputs, and additional advances are expected.
Steele: How is a blue-emitting InGaN diode laser used to create white light?
Rudy: Just as in the case with using a blue LED as a pump source for creating white light, a phosphor is required. There are several options for pumping the phosphor, including transmissive (the white light emission is in the same direction as the pump beam) and reflective (the white light emission is at an angle relative to the pump beam). Also remote pumping, in which optical fiber is used to direct the laser light to the phosphor, is possible. This is the approach used by European automobile manufacturers to develop laser-based headlamps. We at SoraaLaser have developed a white light module using a reflective approach in which the diode laser pumps a small phosphor chip, which emits up to 500 lm of white light from a 300-μm spot. This approach is shown in the figure.
White light being generated by laser light sources.
Steele: What are the advantages of laser sources compared to LEDs for producing white light?
Rudy: As noted above, these laser-pumped phosphor light sources do not suffer from droop, so high conversion efficiencies at high optical pump power are achieved. Laser-based white light sources have very high luminance values (1000 cd/mm2) relative to LEDs, so hundreds of lumens can be emitted within a small beam angle (1–2°), allowing for a high degree of optical control using very small optical elements. The laser-based sources can also enable a convergence of projection display with miniaturized luminaires for projection illumination applications.
Steele: What applications do you envision for laser-based sources?
Rudy: Clearly, laser-based sources are not suitable for all lighting applications, such as broad area illumination. However, we are exploring a number of applications in which such sources are highly advantageous. These include micro-spotlights and micro-luminaires for directional applications in architecture and entertainment, and fiber-delivered, high-lumen ultracompact outdoor lights for roadways and stadiums. We are also exploring applications such as Li-Fi systems with very high data rate capacity relative to Wi-Fi and LED Li-Fi.
Steele: When do you expect laser-based light sources to be commercialized for general lighting applications (as noted above, they are already being used in car headlamps)?
Rudy: In the past 3 years, laser-based displays have emerged to consume substantial volumes of laser-based light sources. Specialty lighting and automotive lighting are now adopting this exciting technology, and will drive a new additional wave of volumes in the coming three years. Beyond that, development is already ongoing to integrate dynamic laser light sources into advanced general lighting applications such as smart lighting, Li-Fi, and IoT [Internet of Things].
A conclusion – LED technology is evolving
Lighting Technology is a continuously evolving field. We are talking now about laser based sources and a few applications the specialists could find for them. In the near future, there is no doubt we’ll witness a development of the range of the applications using laser based lighting technology.
The mankind has still lots of innovations to be discovered and to be put into practice and the lighting technology couldn’t stay aside.
Till next time!
Now that you’ve read about the led lighting advantages in front of the classic ones, which use incandescence technology, and you’ve set your mind to buying LED bulbs, it’s time to move on a bit and explain all the data you’re about to see on the packages of LED Light Products.
Have you ever wondered what those figures and letters meant? Do you know what CRI stands for? What about WW? No, it’s not the World War or something, it’s all about the LED data you have to take into consideration when buying LED. And it’s not complicated at all…
Let’s take, for example, the data of one of our best selling products – LED Bulb B020. This is the description of this LED bulb:
In order for you to understand how to read the LED lamp data, we’ll take all the information and make it easy for you to compare it to other lighting fixtures characteristics.
Model No. – this is the model number of the specific product. Don’t try to interpret it – usually the producers use internal codes to name their products and we, at EXE Holding, do exactly the same. Instead of giving the LED bulbs fancy names, we prefer using internal codes which tell us at a glance all the characteristics of the product just by looking at the model no. itself. For example, the B020-4W-WW model tell us it’s about a LED Bulb from the B020 family of products, using 4W power and displaying a warm white light. Cool?
Power – the LED bulb efficiency is displayed in Watts. The less watts are used, the lesser the energy bill, right? Right! But still – DON’T CONFUSE LIGHTING EFFICIENCY WITH POWER!!!
In the era of incandescence lighting, it was easy to pick up a brighter classic bulb – of course, a 100 Watt incandescence bulb is brighter than a 60 Watt incandescence bulb. Now, comparing LED bulb Watts with incandescence bulb Watts would be a mistake – you simply won’t find anything like 100 Watt LED Lamp – it would be too strong to mount it in your home!
So, you simply take this table beautifully designed by the guys from CNet:
Now you’ve grasped it, right? Watt is the unit we use to measure the consumption of electricity and, during the incandescence era, when a LED bulb had 100 Watts, it used more electricity than another one of, let’s say, 60 Watts, but in the same time it displayed more light than the second one.
In the era of LED Lighting, though, things have changed – the LED bulbs are designed to be more efficient than their incadescence “ancestors” and therefore they use less energy from the very beginning. As you can see above, a 8-12 W LED bulb lights as bright as a 60 W incandescence bulb while the 16-20 W LED bulb lights as much as a 100 Watts incadescence one.
So, don’t be confused – Watts is about power consumption, not about lumens, ok? Next time when you see a 10 W LED bulb displayed on a shelf somewhere, you’ll know it is like a 60 W classic bulb only 5 times more efficient!
Color – white LED Light can basically have the next hues:
- White (W)
- Natural White (NW)
- Warm White (WW)
Of course, LED Light bulbs can have any color you might imagine, but the “whites” might be confusing to some of the clients – what is white, what is natural white and what is warm white?
First, you have to know that the color of the LEDs is measured in Kelvins. It means, the more Kelvins a certain LED bulb has, the “warmer” is the color (yellower).
As a comparison, when it comes to incandescence bulbs, their light has between 2700 and 3500 Kelvins. If you’re looking for this kind of “warmth”, buy LEDs that display this amount of Kelvins. If you’re looking for a warmer (yellower) or a colder (whiter) light, buy LEDs bellow those figures or above those figures. As simple as that.
For additional information check the next chart:
Lumen – this is the measurement unit for the luminous flux and it shows the level of light emitted by the lamp. As you can see in the characteristics chart of our LED bulb, it emits between 340 and 560 lumens. If you check in the other chart, you’ll notice that this kind of luminosity is acquired by an incandescence bulb of 40-60 Watts. Now you know where to look when you need this kind of comparison for deciding upon the best product to buy when it comes to LEDs.
Voltage – here it is very simple – if the normal socket voltage of your country is displayed (100-220), than the LED product is good to be used for the circuit from your home. As you can see in the chart of our B020 LED bulb, it uses both 100 and 220 Voltage systems – it means the product is good both for the American market (arguably the most important one that uses 100 Voltage system) and for the other markets which use 220 Voltage in their national electricity systems.
CRI – Color Rendering Index – this one is important and it shows the ability of that particular LED bulb to reproduce the colors of the various objects faithfully in comparison with “ideal” sources like natural sunlight or incandescence light. Basically, you’ll find numbers above 95 CRI for sources like incandescence or halogen lamps. LED bulbs tend to have 80 CRI or bellow, at this moment. It means they tend to approach “natural light” CRI but they’re still not there. In the near future they’ll solve this problem as well – have no doubt about that!
PF – Power Factor – on everybody’s language, Power Factor shows how much energy a certain LED Light bulb wastes. If the ideal is a PF 1, all those 0.9-0.8, for example, shows that 10%-20% of the energy is wasted on anything else than lighting. The above 0.9 of the LED Bulb B020 is a good number, by the way…
Beam Angle – this is important as well when it comes to comparing LED Light with Incandescence Light; LED bulbs are superior to classic bulbs – while first have the potentional of directional lighting, the last ones difuse the light around them. Thus, you can use LED bulbs of a certain type to direct the lighting to a certain spot, making it more efficient.
Now you know…
Have you ever imagined how it is to pay 80% more on electricity bills just because the incandescence light bulbs use 80% of the energy to heat your house? Yes, you read it well: to heat your house. In fact, you do it month after month – 80% of the cost of the electricity bills go to…heating your household! Of course, there is no such major improvement for the overall temperature inside your cozy home, but you still pay for it, don’t you?
This is just one of the weird facts and disadvantages of incandescence lighting compared to LED lighting…wanna see some of the benefits of LED over conventional technology?
5 LED light benefits over incandescence lighting
1. Longer Lifespan
We all know conventional or incandescence light bulb’s lifespan – it’s about 1,200 hrs. Pretty impressive, right? 1,200 hrs seems so much… But it’s not! It’s only 50 days. Of course, you won’t keep any light bulb lit for 50 days, but still – if you intend using it 24/7, it will last for only 50 days…if it does!
Imagine a more realistic scenario – you came home at 7 pm and turn on the incandescence bulbs in your house – you keep them on until 11 or 12 pm, when you turn them off. It means 4-5 hrs of artificial lighting every day. Well, at 5 hrs of lighting every day, an incandescence light bulb will last only…240 days, which means 8 months. Of course, if you’re a kind of person who needs a light bulb on all night, it will last only about three months or so.
Anyway, let’s get to serious stuff now – how would it be if that particular light bulb will last…50,000 hrs? Yes, you read it right – 50,000 hrs of continuous functioning! This is impressive and it can’t even be compared with 1,200 hrs.
Yes, the LED light bulb is guaranteed for 50,000 hrs! It means almost 6 years of functioning without any problems! 6 years! Compare it to 50 days…
By the way – the latest LED technology guarantees some of the products for 100,000 hrs! You do the math now…
2. Energy Efficiency – LED Light bulbs are much more energy efficient than conventional ones!
As we told you in the beginning of this article, incandescence bulbs use 80% of the energy just to heat the room! Of course, they are not intended to do that, but the reality is that 80% of the energy used by the conventional light bulbs is consumed on any other thing than lighting, including heat.
80% – pretty huge… Imagine your electricity bills with this percentage off! Get it?
Of course, if you’re concerned only about your household energy efficiency, than this percentage means a hundred or a few hundred dollars a month – a decent sum by most of the people’s standards. But what if you’re the manager of a warehouse and you spend a few thousand dollars each month on electricity bills – 80% off means a lot more, isn’t it?
This is in fact the main reason why people choose LED fixtures instead of incandescence ones – the energy efficiency of the LED technology, which finally have a strong impact on the electricity bills. As simple as that!
3. Durable Quality – LED Lighting fixtures are made to survive in any conditions
Unlike incandescence bulbs, LED Lighting is a technology which outstands the harshest environment conditions – heat or extreme cold exposure, rain, snow, strong winds, etc. LED Light fixtures don’t need a vacuum glass chamber, nor an incandescence filament of any sort. LED means Led Emitting Diode, as we showed you. Have you ever seen a diode? It’s a sturdy tiny component which…emits light! It doesn’t need any glass or any other breakable materials to do that.
This leads us to another advantage of LED Lighting fixtures over the incandescence ones…
4. Design flexibility – LED Lighting fixtures can take a variety of shape and sizes
Incandescence lighting means bulbs, vacuum chambers, filaments, etc. In other words, conventional light fixtures are supposed to be of certain shapes and dimensions to be able to “host” the incandescence light bulbs. So, this is the reason why the design of the conventional ceiling lamps hasn’t changed a bit since the beginning.
But what if your ceiling lamp fixtures would take any shape and size, without any “silly” questions from the designers like “where should we put the light bulbs if we draw the fixture like that”?
Now, due to the dimension of the diodes (a few millimeters), only the imagination is the limit for LED lighting fixtures designers…
5. Safety – LED bulbs are much safer than incandescent ones
Because it doesn’t produce heat, you can let a LED bulb functioning for no matter how many hours or days without the fear of overheating itself or something around it, let alone “put fire” to something, God forbids! You can touch a LED Light bulb while functioning without the fear of getting burned, you can drop the LED light fixture without the fear of causing short-circuits or breaking or even damaging it. It is simply much more reliable, more durable, much more safer than any other lighting technology on the planet.
