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.
