We don't recommend any of the compact bulbs. They aren't nearly as reliable as the tube bulbs are, some have been known to cause eye problems, and many have a high burn in rate so that they stop producing sufficient UVB for your dragon after a short time. Without a UVB monitor to measure the UVB being put out, I wouldn't risk it. Better to stick with the tried and true bulbs - either a MVB or a UVB flourescent tube bulb.
