Ours was not. Long story short- their red light broke, it was going to be sub zero with a wind chill of -25 last night so my husband offered me a 250 watt bulb to borrow from his work truck until I could get back to the store. It was only meant to be temporary because it was clear and too bright for overnight. The bulb is meant for use in the wing bars they have at the grocery store. He said they put 8 of them over the chicken and onion rings etc. 8- over food even little kids might eat- who knew one 5 feet off the floor in the coop would be so dangerous? We had no idea. But no, these bulbs are for commercial food equipment- not something you'd buy at a regular store. But- they do sell coated bulbs at stores I believe. Just be safe- it never once crossed my mind that could be deadly- until it was too late.
