Total U.S. greenhouse gas (GHG) emissions were 6,576 million metric tons carbon dioxide equivalent (MMTCO2e) in 2009, a decrease of 5.8% from the 2008 level, according to Emissions of Greenhouse Gases in the United States 2009, a report recently released by the U.S. Energy Information Administration (EIA). Since 1990, U.S. GHG emissions have grown at [...]
In collaboration with the California Lighting Technology Center (CLTC) at UC Davis, EverLast Induction Lighting, a product of Full Spectrum Solutions, introduces The BioLume Series. The new patent-pending lighting series is a collection of hybrid bi-level fixtures that utilize a 5000K induction lamp and amber LEDs, coupled with occupancy sensor controls. When the area is [...]
I’m pleased to announce that I have finally completed the long awaited (by my publisher) update to The Lighting Management Handbook, which came out in 1994, with this 300-page book about redesigning existing lighting systems: Lighting Redesign for Existing Buildings. Because light is used to see but cannot be seen, it is often overlooked by [...]
Today is Earth Day.

Part of the backlash against compact fluorescent lamps has been that they contain mercury. The argument doesn’t hold up on one level, which is that incandescent lamps require more power, which means power plants must burn more fossil fuels to satisfy that requirement, and thereby emit more mercury into the environment than CFLs. This type [...]
Litecontrol has earned the prestigious Cradle to Cradle Certification for the fourth year in a row. This third-party certification has to be renewed annually, assuring ongoing improvements in sustainability. The C2C process assesses every nuance in product design and manufacturing, examining details from fixture ingredients to manufacturing practices to renewable energy initiatives. As part of [...]
Christmas strand, traffic light and automobile LED lights marketed as safe, environmentally preferable alternatives to traditional light sources may reduce air emissions at power plants by using less energy, but nonetheless contain lead, arsenic and a dozen other potentially hazardous substances, according to newly published research. Scientists at UC Irvine and UC Davis crunched, leached [...]
