THE COMPARISON OF ONCE® LED FIXTURES VS. CFL LIGHT BULBS2016

BACKGROUND

This study was conducted by ONCE® and one of the largest egg producers in the world (company name is con�dential). It compared ONCE® layer-speci�c Dim-to-Red® LED lighting technology with regular CFL light bulbs.

STUDY DETAILS

Teams followed 250,000 hens in 5-tier, caged housing through a 70-week laying period. • Two treatments with 125,000 hens per treatment compared ONCE® LEDs with CFL light bulbs. • Egg count and weight were taken by the house data collection system to produce mortality rates, body weight and uniformity in �ock. TIMELINE • 2015 March 17 - Chicks hatched • 2015 July 19 - Data collection and recording begins • 2015 July 24 - First eggs laid • 2016 March 26 - The CFL egg weight dropped below that of the LED egg weight (25 vs 27 egg lbs/hh)

RESULTS

Birds housed under ONCE® LED lighting systems produced an average of 28.6 more eggs per hen housed during the 70-week lay period, resulting in about 8% more eggs produced overall. Both treatments had similar mortality (~5%) and uniformity.

CONCLUSION

Better light distribution and species-speci�c spectrum are possible reasons for the improved results. The ONCE®

LED distributed ~22 lux on tier 1, ~20 lux on tier 3 and ~20 lux on tier 5, while the CFL distributed ~20 lux on tier 1, ~10 lux on tier 3 and ~6 lux on tier 5.

The results imply that over a 70-week period, a 300,000 bird house using light by ONCE® AgriShift® MLM-R lighting �xtures could produce an additional 1.1 million pounds of eggs when compared to birds under light from CFLs. In addition, birds have the potential to produce an additional 8.5 million eggs in 70-weeks under light by ONCE® AgriShift® MLM-R vs CFLs. This is an extra 24,000 eggs per day on a 300,000 bird house.
