LED and other technologies have revolutionized the lighting industry. We now have more options, more value, less energy use, and more synergy and integration in our lighting ranges than ever before. We all know LED lights use vastly less electricity and last a great deal longer than incandescent and CFL lights, but here are some interesting things you probably didn’t know about LED and other lighting technologies.
1. LEDs are all about visibility
There’s one main reason LEDs use approximately 80% less energy than incandescent/halogen lights: they use all the electricity to generate visible light. Well, that sounds pretty obvious, I hear you say, but the key word here is ‘visible’. All the light that comes from an LED is at a wavelength we can actually see; there is no wastage.
I’m sure you will have never seen this advertised on the box, but incandescent, halogen and CFL lights produce mostly light we can’t see. That is, only 15% of the energy becomes physical light, the rest is heat, infra-red, ultra-violet, and various other by-products that are not visible light. Therefore, the driving force in the LED revolution is the massive improvement in efficiency.
2. Insects don’t much like LEDs
Bugs love porch or verandah lights about as much as Kim Kardashian likes a camera. This is one of the consequences of the IR and UV light that is produced by fluorescent and incandescent lights. LED light, while not completely eliminating the attraction (bugs still like the normal light too), will greatly reduce your bug and moth problem. Probably also a better option than the bug zapper in the corner interrupting your peaceful dinner playlist. Ahh, the serenity!
3. LEDS go easy on their surroundings
Another advantage of LEDs not emitting IR and UV radiation is how gentle they are on paintings, manuscripts, and pretty much everything really old. Museums and art galleries around the world were early adopters of LED. The UV and IR of previous types of light fittings actually damage centuries-old paintings and materials, which is why they were never brightly lit and would remain in darkness when the art gallery or museum was closed. LED means they can not only light them brighter and for longer, they also have control over color temperature, and all while protecting and preserving these valuable artifacts.
Tip: In most cases, an experienced lighting designer will tick all the legal building code boxes, while also designing a home’s lighting to be efficient. They will generally have a wider range of fittings in their arsenal and will be able to better light a room without over-lighting it, while adding creatively to the decor or motif, and introducing to you the wonderful benefits of dimming, sensors, schedules, and lighting control.
4. Dimmable LEDs are getting smarter
Throughout the evolution of humans, sunlight has always been the clock that determines our sleep routines, or ‘circadian rhythms’. Science has proven many times over that artificial light can offset this internal clock and can actually prevent us from falling asleep. Experts recommend dimming lights leading up to bedtime, and using warm light rather than cool light, simulating a sunset.
Luckily LED lights can be dimmed, and new technology is emerging that lowers the colour temperature of the light as it is dimmed down. Imagine the light is on full and looks natural, then the further you dim it down towards off, it becomes warmer and warmer like a sunset. Install these appropriately named ‘Sunset Dimming’ lights in the bedroom and lounge room, and you’ll be a lot closer to a great night’s sleep and improved wellbeing.
5. LED Lighting sensors have evolved
Hard data is not readily available but many experts estimate that 40 per cent of our lighting bill comes from unoccupied rooms. The parents reading will certainly relate to the regular ritual of turning off all the lights in rooms not being used. The answer to this dilemma is to install lighting sensors. You’re probably familiar with them for outdoor floodlights, but sensors can be used inside as well.
For rooms like pantries, laundries, and utility rooms, sensors can be installed instead of a switch. In other rooms, you may not have the sensor turn on the light, but the greatest advantage of sensors is they can run a timer to turn off the light. Therefore when someone leaves a room, after a predetermined time of 5 or 10 minutes, the light is turned off. If you re-enter the room before the light goes off, then the timer is re-triggered and starts again. Essentially, empty rooms will automatically turn off the light after a set amount of time, saving energy, money, and your sanity.
6. LED Lights can adapt to the daylight
It’s very common in new office buildings to utilise ‘daylight harvesting’, and it’s quite an amazing technology. Essentially, a designer will nominate the light level required in an open space up front. Light level sensors are installed throughout, then when the daylight coming through the windows is less than the designated light level, lights are automatically turned on and are dimmed to a level that brings the ambient light up to that pre-determined level.
On a bright, sunny day the lights may be dimmed to 5 or 10 per cent; on a cloudy or rainy day the lights may need to run at 80 or 90 per cent, so overall we are using way less energy. The main benefit after energy saving is consistency of light level. The person occupying the room may not even be aware the lights are dynamically changing brightness to compensate for any loss of daylight. Daylight harvesting is now beginning to be used in homes, particularly in rooms where consistent lighting is useful, such as kitchens, laundries, studies, garages, and workshops.
7. LED Lighting systems are becoming pretty amazing
Technology can be a beautiful thing, and when it saves energy as well as significantly improving the functionality and liveability of your home, it’s well worth considering if you’re building a new house. Full lighting control systems such as BMS – Building Management Control (you decide which switches control which lights), more flexible (change your mind, change your programming), and more beautiful (dimming, mood lighting, architectural lighting).
Systems like these can also add convenience (one switch can set a global scene such as ‘All Off’ or ‘Welcome Home’), can be safer (sensor lighting and integration to alarm systems), thrifty (use less electricity and extend bulb life), and smarter (you can control all your lights from smartphones and iPads). Lighting can also be integrated with mechanical systems, irrigation systems, window treatments, air conditioning, ceiling fans and your audio/visual system.
8. LED Lights can be voice activated
Expanding on the technology and lighting control systems mentioned above, did you know you can control your lights by talking to them? Apple, Google, and Amazon all have systems with voice control that can respond to your verbal commands. This technology doesn’t just apply to homes with significant investment in full lighting control systems, but can also be implemented by just installing several compatible smart bulbs from partnered manufacturers. So get excited, saying ‘Lights on’ as you walk into your home and getting an instant result is here, right now.

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.

Original article on Houzz.com
Along with the evolution of the digital systems we entered the era of IoT (Internet of Things) and along the path we witnessed the birth of intelligent cities and intelligent buildings as a result of the need for energy efficiency while consuming more and more natural resources and electricity.
The rapid economic growth of certain urban areas leads to the need of a growing quantity of electricity. Hence the question – how should we diminish the costs with the electricity bill while asking for more and more electricity consumption? Of course, the answer is “energy efficiency”…
While in the previous articles we have talked and learned about the energy efficiency through LED technology, we have to mention that this is not the only solution you can use for significantly diminshing the costs with the electricity bills. Another way is by using BMS – the Building Management System.
What is BMS – Building Management System?
BMS, or Building Management System, is, as its name says, an integrated management system for buildings and it deals with the integrated and supervised control of the equipments installed in a building for reducing the consumption of the energy and optimizing, functioning and enhancing the confort and security of its inhabitants.
Building Management System (BMS) or “the brain of the building” allows the integrated management of a building, administrative and logistic, offering those who dwell or work here an enhanced degree of confort and security, along with reducing the costs with the maintanence and utilities.
Such a BMS system can monitor and control:
- HVAC system
- Exterior and interior lighting system
- Energy, gas and water supply system
- Other automatized activities – the opening and shutting of the windows or doors, etc.
Which are the other systems to be integrated with BMS?
You can integrate BMS with:
- Security and access control system
- Fire detection system
- Video surveillance and burglar alarm system
- Public address system
- Power supply and electric generator systems
What are the benefits of BMS?
By purchasing a BMS solution from EXE Green Holding, you can benefit from it as it follows:
- by reducing the overall costs following the reducing of the energetic consumption of the building
- by raising the confort degree of the dwellers
- by enhancing the security along with the enhancing of the control over the building
Reducing the costs with the energy
The reducing of the costs with the energy will be accomplished through controlling certain parameters such as temperature, humidity and illuminatio, depending on the day/night period, outside temperature and the way the activities are conducted in that particular building.
Increasing the confort degree
Increasing the confort degree is the first visible result of such a BMS System – an intelligent building will independently react to the environment changes without human intervention: the windows can automatically open for letting the air in and can be automatically shut when raining; also, the sun shades can be opened or shut depending on the position of the sun, the temperature inside can be automatically adjusted to the presence or the absence of the human presence inside the building and certain areas, the illumination can be automatically adjusted to maintain a certain degree of luminosity disregard of the daytime and so on. Another feature that can add value to a BMS system is mobile control through mobile apps.
Building security can be analyzed from two perspectives:
- security which protect you from vandalizing or burglary
- security which deals with water leakage, fire, gas leakage, etc.
The using of BMS technology for building lighting
The using of BMS technology for controlling the building lighting also manages the remote control and monitoring through IP VPN and LON of LED lighting devices.
The implementation of BMS lead to the reducing of energy consumption by 20% and along with that the increasing of the functioning life of the LED fixtures.
The interface for the user of BMS system allows the turn on/turn off and the dimming of the luminous flux of the LED fixtures, individually or for logic groups; the easy programming and reprogramming of the functioning profiles (on/off/dimming level) for different working hours; map visualisation and the status for each and single LED Lighting fixture and for electrical parameters automatically and local measured.
The BMS software is compatible with mobile platforms and devices (mobile phone, tablet), with desktop platforms (for Windows or iOS), with embedded systems (Raspbery PI) but also with WEB platforms. The graphic interface also allows the control and monitoring of the different apllications simultaneously.

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.
