Lighting Understanding for a More Efficient Nation

Growing up as LED lights come of age

Growing up as LED lights come of age

Two years ago we changed all the halogen ceiling lights in our home to light emitting diodes (LEDs). What joy! Our LEDs are brighter than the lights they replaced, they use less electricity, they mimic the colour of sunlight, they have not visibly aged since they were installed, they work with dimmers and they are safer in the ceiling cavity because they do not run nearly as hot as the halogens.

LED light bulbs keep improving in efficiency and quality

LED light bulbs keep improving in efficiency and quality

Improvements in lighting technology for light-emitting diode (LED) bulbs have increased lighting efficiency, or efficacy, as well as color quality. In September of this year, several manufacturers released ENERGY STAR®-qualified bulbs surpassing 100 lumens per watt.

Lightbulb efficiency improving under federal rules

Lightbulb efficiency improving under federal rules

The efficiency of light-emitting diode (LED) bulbs have improved greatly in recent years as federal mandates have tightened, the Energy Information Administration (EIA) reported. Under a 2007 law, the Energy Department has banned the sale of incandescent lightbulbs and some other inefficient technologies.

‘Lighting Season’ Has Begun: What Better Time to Buy an LED Bulb and Save Over $125?

‘Lighting Season’ Has Begun: What Better Time to Buy an LED Bulb and Save Over $125?

Now that we've completed the annual ritual of setting our clocks back an hour with the end of Daylight Savings Time, we're in "lighting season" where the days get shorter and our lights stay on more hours per day. But because roughly two out of every three bulbs in America's light sockets are still the inefficient ones, we're spending billions more than we need to light our homes.

Turn Out the Lights for CFLs

Turn Out the Lights for CFLs

If you’ve been shopping for light bulbs lately, you know that the old-fashioned tungsten light bulb is a thing of the past. In 2007, Congress, along with President Bush, effectively banned tungsten light bulbs by passing a law that required energy efficiency far in excess of what the old tungstens could deliver.

LEDs are good but can do better, inventor says

LEDs are good but can do better, inventor says

Using light-emitting diodes (LEDs) to illuminate homes, offices, roadways and parks saves energy compared with most conventional bulbs. An LED lamp uses one-quarter of the energy and can last 25 times as long as a traditional 60-watt incandescent bulb.

Everything you wanted to know about LEDs but were afraid to ask

Everything you wanted to know about LEDs but were afraid to ask

The Nobel Prize in Physics just awarded to Isamu Akasaki, Hiroshi Amano, and Shuji Nakamura for their work on blue light emitting diodes—LEDs—reveals the extent to which lighting technology has changed over the just the last four decades.

Sports stadiums embrace the advantages of LED lights

Sports stadiums embrace the advantages of LED lights

For years, sports stadiums have used metal halide lights to illuminate playing surfaces. But now, arenas are turning to LED lights, which have already made inroads in everything from city street lights to Christmas lights.

LED There Be Light: 3 Share Nobel For Blue Diode

LED There Be Light: 3 Share Nobel For Blue Diode

An invention that promises to revolutionize the way the world lights its homes and offices - and already helps create the glowing screens of mobile phones, computers and TVs- earned a Nobel Prize on Tuesday for two Japanese scientists and a Japanese-born American.

What’s In A Light Bulb?

What’s In A Light Bulb?

Governments around the world are gradually phasing out the energy-inefficient incandescent light bulb, but many homeowners have yet to make the switch. To help break down the differences between light bulbs and explain how buying more energy efficient alternatives is a sound economic and environmental investment, Angie’s List put together an infographic that covers everything from the definition of a lumen to the a cost comparison of electricity output.
