"Egg crate", if I recall, is used in lighting in buildings, so I don't think there is worry about heat. However, are the spaces at least 1/2" wide? If not, there will be a drastic decrease in UVB potency. I would imagine that some heat would be lost, but the only thing you can do is try it out and measure the temps and see what happens.
