OK, so I trimmed the sides a wee bit I cut the side plates to where they are only 1.5 inches off the edge of the folded shroud. They look more like boomerangs now, but it runs a lot cooler. Doesn't matter anyway because the side pieces are just there to keep the shroud piece from slowly unfolding or bending out of shape... The good people at GE told me these bulbs ran so cool I could safely run as many of them as close together as I wanted. Yeah Right. Anyway, I'm going to add some 3 or 4 inch computer fans to blow air across the bulbs and across the topside, and post back. Will have more pictures soon too...
