Abstract. The need for energy efficient, cost-effective, reliable light bulbs for broiler production is evident. This paper reports on a field test of three LED and two CFL bulbs in commercial broiler houses over an 18-month period. Differences in dimming curves, lighting efficiency, power/apparent power curves, light distribution, and lumen depreciation were noted for each bulb. Although initial lighting levels were noticeably different, all bulbs except the Life Lamp LED had depreciated within about 6 months to approximately 1.2 to 1.3 ft-candles and remained there for the next 12 months. Life Lamp LED only had 6 months in the test at time of last measurement and appeared to be still depreciating, but was still at 2.5 ft-candles. Some of the bulbs had low power factors, especially when dimmed which is a matter of concern for power companies. Different bulbs will require different programming of dimmers or at least recalibration to achieve desired lighting levels since each bulb tested responded differently to dimmers.
