All Freshlight lighting systems closely copy the balanced light spectrum of sunlight. Sunlight is comprised of all the colors of the rainbow plus UV A, B, and C. Freshlight beautifully balances each wave length of light, to include UV B which is needed to activate the penal gland and produce vitamin D3. Vitamin D3 is used by chickens to improve their digestion, enhance their immune system and metabolize phosphor and calcium to make stronger bones and egg shells. We leave out the harmful UV C wave length.
Many companies claim they produce full spectrum lights but fail to balance the wavelengths or include UV A and B. You may not be able to see that a light has too much blue, red, yellow or green, but chickens can see all light wave lengths and chickens respond differently to each wave length of light. Improper lighting causes stress on chickens and other animals affecting their overall performance. Different wave lengths of light can affect how well a chicken eats, processes food, reproduction rates, makes them active or inactive, nervous or calm. Naturally balanced sunlight provides the best environment for healthy animals and Freshlight provides the best copy of natural sunlight.
