Performance Enhancement For Residential Light Fixtures
September 10, 2008 11:51 am | by by Jason Lomberg, Technical Editor | Blogs | CommentsIn a recent beer commercial, a woman asks for a low-calorie beer, and the host proceeds to spill out half the bottle, and hand it to her. In similar fashion the EPA believes that, through the use of add-ons, one can improve the innate efficiency of legacy technologies. In reference to their new Energy Star “technical amendment,” the EPA’s Lightning Program Manager, Alex Baker, told me, “With this approach, the Program currently has nearly 12,000 qualified fixtures from more than 120 manufacturing Partners…even incandescent technologies (the latter only allowed when used with a motion sensor to minimize operating time)” (emphasis mine).
