I just bought a 100w ceramic bulb for my 6x8 coop. Man they are EXPENSIVE! I plugged it in under my desk to make sure it works and I can barely feel the heat at all. Seriously - like AT ALL. Even the general air under my desk doesn't feel warmer. When I put my hand close to it, I can feel the heat, but once I back off 4-6 inches, it's all lost. In my MN coop it is going to be a complete waste of time (and money). I know there are zillions of you out there who don't believe in heating your coops, and believe me, if I can get away with it, then I won't.... but I only have 4 hens and they don't even begin to heat up their insulated coop with their body heat. And it's a l*o*n*g and bitter winter season here in MN... so be patient with me here, okay? How warm are these things supposed to get? Do they take a long time to reach peak heat potential or something? It's been going for 30 minutes and I'm not feeling impressed. In fact, I'm feeling kinda gypped. I envisioned heat like a red bulb, but with no light. This isn't even close. Did I get a bummer bulb or have I chosen the wrong tool for the job? I wanted to save it for when the temps start hitting single digits (and below) but I can clearly see that this particular bulb won't even matter. Can some folks with ceramic heat experience teach this young padwan learner? Thanks!
