Validation of a new LED light bulb designed for the egg-laying industry Principal Investigator Grégoy Bédécarrats, University of Guelph Year the work was done 2013-2015 Overall objective To validate a new LED light bulb designed for the egg-laying industry. Outcomes Validation that the spectrum LED bulb (60% red light) was more efficient at stimulating the reproductive axis to promote reproduction (egg laying). AgriLuxTM PLR bulb (60% red light) reduces feed consumption without impacting egg number/quality or birds’ health and welfare. The developed 10W LED bulb consumed over 80% less electricity than an equivalent 60W incandescent and 25% less than a 15W CFL. Confirmation that red light is more effective at stimulating the reproductive axis, specifically the effect of red light in triggering the activation of the hypothalamo-pituitary gonadal axis. A new design for the socket piece was implemented to enhance the quality and reliability of the product specifically for industrial pressure wash procedures used commercially. Application The spectrum LED bulb is now commercialized under the AgriLux trademark name in Canada. This research applies to Layers
