The light output and lamp life of compact fluorescent (CF) lamps placed in three commercial caged-layer poultry facilities were studied. Only 7- and 9-watt CF lamps were used. This study revealed that the 7-watt lamp maintained 82% of its original light output with 34% of the lamps still operating after 23,000 hr of on time. The 9-watt lamps maintained 71.84% of their original light output with 34% of the lamps still operating after more than 23,000 hr of on time. The mean failure rate for both 7- and 9-watt lamps was 21,480 hr with no ballast failures.

Key Words: Compact fluorescent lamps • lamp life • lumen maintenance • poultry
