Yesterday we put in a 5.5 inch clamp lamp with a 150 watt infrared bulb in our 4 x 8 coop. It just now dawned on me to look up online what the clamp lamp was rated for and it is only rated for a 75 watt incandescent bulb !!!!!!! I know I need to go get a different lamp tomorrow but will it be safe till then ? ....another sleepless nite worrying about the chickens...
