Recessed can downlights are a very popular form of lighting with many new homes containing 20 or more can lights. This trade magazine article describes PNNL's work with DOE's Emerging Technologies Program to promote energy-efficient recessed can downlights. PNNL manages the Recessed Can Downlights Project, which encourages manufacturers to produce energy-efficient recessed cans and tests them to verify that they have the following features: use pin-based CFL bulbs rated for 10,000 hours of life; use airtight housing to prevent air leakage into attics; are IC-rated for direct contat with insulation; have electronic ballasts for quiet, flicker-free operation; and have a min. light output of 900 initial lumens. Can lights that qualify are promoted through a DOE website. This is under DOE's Office of Energy Efficiency and Renewable Energy Building Technologies Program.
