Are there health or environmental concerns with LED lights?

April 15   3 Comments  

LED bulbs appear poised to displace compact fluorescents (CFLs) as the king-of-the-hill of green bulbs, but a study published in late 2010 in the journal Environmental Science and Technology found that LEDs contain lead, arsenic and a dozen other potentially dangerous substances. (Thinkstock)

Which light bulbs are the greenest?

Oct. 23, 2011   1 Comment  

As the future gets dimmer for traditional incandescent light bulbs, and compact fluorescents (CFLs) fall out of favor due to their toxic mercury component, light-emitting diodes, or LEDs, are beginning to come on strong. LEDs, which are clusters of small bulbs that come in many shapes and sizes, last five times longer than CFLs and 40 times longer than incandescents and use much less energy.

Improving light bulb energy efficiency

Sept. 5, 2011   Leave a Comment  

New efficiency requirements for light bulbs may sound the death knell for incandescents, which have not changed significantly since Thomas Edison invented them in 1879. Newer, more efficient styles cost more but could save consumers some $6 billion in annual energy costs by 2015 -- while also eliminating the equivalent of 30 large power plants' electrical output and 14 million cars worth of carbon emissions.

EarthTalk: LED bulbs? Motor oil?

Oct. 20, 2008   2 Comments  

Dear EarthTalk: What’s the story with LED light bulbs that are reputed to be even more energy-efficient than compact fluorescents? — Toby Eskridge, Little Rock, AR Perhaps the ultimate “alternative to the alternative,” the LED (light-emitting diode) light bulb may well dethrone the compact fluorescent (CFL) as king of the green lighting choices. But it [...]
