Yes, I have seen this coming for awhile. Mostly, I will use broody hens so I will not need the bulbs. When I have chicks in the winter (as now), I too have been using the Brincea Eco-glo -- I have one 20 and one 50. One thing about them, the chicks jump on top of them and poop all over them & pain to clean every day. I thought of putting a pice of cardboard the size of the top. Any other ideas? I agree they are not cheap. The chicks love them (I call them an artificial hen) & I like the fact there is not a light on 24/7 & they are safe.Love my Brinsea Eco-glo's but they are not cheap either. I have a 20 and two 50's. I believe the manufacturer recommends not using them in temps under 50deg. but I use them all winter in my brooders in a horse stall outside.
