This is so cheap and generates alot of heat!  Learned this from my sailing days...we used to put a clay pot over the stove burner to heat the boat on cold nights.  This one uses a 100w light bulb that I have wired into a clay plant pot, taped the bottom of the pot onto the top of the pot, and voila, completely sealed, no light output.  I just put it on top of two small patio stones so it doesn't touch the shavings.  My brooder is a pen out in the shed and it is well below zero here right now.
