For many buildings, switching to more efficient lighting is one of the “low hanging fruit” for improving energy efficiency. Facility managers are increasingly turning to LED lighting technology to meet their energy efficiency goals.
LED bulbs top the lighting charts in energy efficiency and longevity, and frequently represent a payback of three years or less. However, LEDs may not be the best choice for every application. When considering whether to implement LEDs in your facility, you’ll need to take many factors into account. Continue reading
Restaurants are the most energy intensive commercial buildings in the United States according to the Energy Information Administration. Restaurants, per square foot, consume nearly three times the energy of the average commercial building. Closets, storage rooms, break rooms and even walk-in refrigerators are great candidates for occupancy sensors. Exit signs using LEDs are a great alternative to incandescent-based signs.
Lighting accounts for nearly 13% of all the energy used in a restaurant. It is one of the easiest places to save money.
For many reasons, use of LEDs in both consumer and industrial applications looks bright. So believes Richard Evans, an engineer who has talked to environmental groups about consumer use of LEDs and has been specifying LEDs for a leading manufacturer of industrial automation equipment for over 10 years.
Consumer products to use more LEDs in the future
In the consumer sector, he is very optimistic about the growth of LED use, especially when it comes to LEDs replacing incandescent and fluorescent lighting and the use of LEDs in television sets. He predicts “the trend toward LED back lighting in TV sets will continue for several more years.” Continue reading
Wherever you go these days, you see businesses switching their lighting systems from old-fashioned incandescent or harsh fluorescent to bright and shiny new LEDs. The local supermarket, the office where you work, the train station, restaurant or department store—all of these businesses are seeing the benefits of this rapidly developing technology. The light produced by LED bulbs is brighter and warmer and more focused than ever before, and business owners love the savings to their energy bills. But what about consumers?
A Texas company that specializes in single-brew gourmet coffee machines and vending machines for offices has joined the ranks of companies all over the world that are seeing the benefits of switching to LED lighting. FreshBrew, of Houston, Texas, announced that it has replaced all the lighting in its 90,000-square-foot warehouse, manufacturing facility and offices, as well as all other interior and exterior lighting.
Some of us resist the switch to efficient lighting, even some who embraced the compact fluorescent, just can’t seem to accept LED lighting around the house.
A fundamental paradigm shift in lighting technologies toward more efficient lamps and bulbs will significantly reduce global electricity demand for general illumination in the next few years, according to IHS.
The energy usage of the installed base of lighting technologies for general illumination will fall to a projected 2.75 trillion kilowatt-hours (kWh) by 2020, down 24% from 3.61 trillion kWh in 2013. Overall, the installed base for general lighting-which covers homes, businesses and street lamps but not architectural or theatrical lighting-will account for 10.3% of the net electricity generated in 2020, down from 16.4% in 2013.

Most people have accepted that it’s all but over for old incandescent bulbs. But CFLs—compact fluorescent bulbs, the titular replacements for incandescents—may be rapidly becoming extinct as well.
It starts with an innocent string of incandescent holiday lights around a porch window, maybe a plastic caroler or two on the front lawn.
Then it escalates: Twinkling lights are in the shrubs, Santa’s on the roof, an inflatable Frosty the Snowman is on the lawn and next to him is one of those little white wire reindeer with a head that turns ever so slowly.
Nice work, holiday decorator. But do you have lights that can be controlled by tracing your finger over the face of a smartphone? Do you have 16 million colors available at the flick of a switch?
