Can LED light bulbs harm your pets?

 A family pet seems to sleep without a care under a lamp with an LED light bulb

Anecdotal evidence suggests that LED light bulbs may have an adverse effect on the life of small animals. A recent post by René van Gemert, CEO at Salescraft, S.L., on the LinkedIn discussion group “Innovations in Light” recounts the tale of a customer who started using LED bulbs at his rabbit farm. The area where the rabbits were kept consisted of three rows of cages that originally had linear fluorescent light above each row. When the customer retrofitted one of the lighting rows with LED tubes, he found that over a three-month period, every 20 days 40% of the female rabbits miscarried. When he swapped the lighting to a different row, the same thing occurred. Rabbits under fluorescent lighting had normal offspring.
Contributors to the group also suggest that chickens may be affected. Causes for the problem proposed by the group include the ripple effect of LEDs and their reduced spectrum of light, particularly UV, from LEDs. It seems that further study will be needed to determine the cause and fix for the problem.
