Importance of light intensity

The intensity or brightness of a lighting system (a separate component from color) is equally important in in maximizing hen performance (ROZENBOLM ETAL ,1998) recent work byEL HAWALANI 2009 provided evidence that red LED lights (630nm wavelength lighting) at 30LUX (or 3 foot candle) enhances egg productions.

Statistics show that coupling the best LED lighting color with the best light intensity can have a major impact on egg production . Eggs/hen/week was maximized at 4.34 plus 0.18 by using the once innovations programmed lighting.
This showed a statistically significant increase of 38 eggs per hen over 27 eggs for a weekly production period. In a barn holding 10,000 laying hens this amounts to a substantial increase in production.
