YES! I tried heat lamps, until I found out that they could shatter and be very dangerous. I knew about reptile heaters, and had used them over cages of birds, but didn't know that I could purchase a 250 watt heat emitter, and the clamp lamp to go with it. It has to be rated for the 250 watts. It throws just heat. No light. I clamp them up over the perches, so that it warms them. Not too close, just hold it up and put your hand under it. That will tell you how far away to hang it. I use a couple of them in my loft. If they are chilly, it gives them somewhere to go to get warm. You can put one up over a shelf or table too. I was just online ordering a backup heat emitter and clamp lamp, and they have wire shields to cover the front, to stop an animal from getting too close to it. I ordered that too. Of course, I like to spend a lot of time in the loft with my birds, so when it gets really cold,I do have one of those heaters that looks like a radiator, and is filled with oil. Electric. I keep it on low generally, and it keeps it very comfortable for the birds around 40 or 45 when it is really cold. When it isn't quite so cold, like during those January or February thaw, on low, it might go up to 50 or 60. You could always turn it off during those times. But if you just want to give them warm places to perch, the heat emitters are great. I've told others about them, and they have liked them. I'll go look for the web address.
