We use these to take the chill off our pet house. we enclosed an area with a metal awning, which our dogs get out of the cold during Winter. One of these bulbs will raise the temperature in the dog house by abou 20 degrees F. It is, for example, 32 degrees outside right now, though the dog room is at about 50 degrees, much better. Of course, we have one of these bulbs mounted in a large reflector lamp and mounted in the center of the room and about 6 feet off the ground, so the animals cannot reach it and injure itself.
