I was at Petsmart buying hamster food and browsing the bird and reptile sections (what cute birdie toys!). With the red heat lamps, they had round ceramic heaters that screw in just like a light bulb. I thought that was pretty nifty, not emitting light and all. Has anyone used one? They are 150 watts. I thought they might be better than the 250 watter, which I heard is very hot for brooders in a regular house, and that it would be nice so the babies could have a natural night (though I'd still use a night light for the first couple days so they could find the food and water).
