Overall objective

  • To validate a new LED light bulb designed for the egg-laying industry.


  • 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.


  • The spectrum LED bulb is now commercialized under the AgriLux trademark name in Canada.
