Here's a list (PDF).Dennis Alwon said:I contend that a CFL in a fixture that says 60 watt incandescent is a violation of the listing of the fixture. I also have never seen a cfl that can go in a fixture that is enclosed, not saying there isn't one- just never seen one.
Quoting from the PDF:
DOE solicited from manufacturers R-CFLs that are specifically designed for use in high heat applications, such as airtight, insulated ceiling-rated recessed cans. R-CFLs that meet the program?s minimum specifications and successfully complete Elevated Temperature Life Testing (ETLT) are declared competition winners.
ETLT involves a minimum of 6,000 hours of operation in a simulated insulated ceiling-rated airtight (ICAT) environment (laboratory testing). The minimum requirement for both this competition and the ENERGY STAR CFL Program is 6,000 hours. Models with rated life claims beyond 6,000 hours are required to continue testing until that claim is met. Ten lamps of each model are tested, and manufacturers are required to pay testing costs. The testing apparatus operates the lamps in an automated cycle of 3 hours ?on,? 20 minutes ?off,? for the test duration. Lamps are tested at an ambient temperature of 55?C. Light intensity for each lamp is measured every 2 weeks throughout the testing period to evaluate lumen maintenance over time. Manufacturers are provided with test results for their lamp(s) on a periodic basis.
