The avian light thing came up in another post recently. My advice is to carefully read the instructions with the light. There is a "burn in" time (number of hours on) during which the light is needs to be about a foot further away. After the burn in time is over, you move it closer. I did that and didn't have any problems with the light hanging over Timber's cage. Another forum member (sorry, I read all the posts and forget who said what) said to watch the voltage or wattage. Hopefully whoever that was will chime in.
