I hadn't thought of that. Thanks! I plan on using the gooseneck 27w 6500k fixture, the one with the quad pin CFL. Do you think that would warp the acrylic?
I don't think it would warp it.
I use a thin piece of acrylic under a similar quad pin CFL (the piece of acrylic is about 2 inches away from the bulb itself), and it has been OK so far. Granted, my light bulb is only 18W, but I don't imagine the extra heat from the 27W fixture would be too much of a problem.
