I have read about the history of the compact bulbs and based on the design, I'm not sure they will ever be safe or effective. I have had a couple of rescue lizards come in with severe conjunctivitis that might have been caused by coil or compact bulbs, and it is not pretty. I wouldn't take a chance.

I would stick with either a Reptisun 10 fluorescent linear tube plus a bright basking bulb, or if your enclosure is a 40 breeder or larger, you can use a Mercury Vapor bulb, which is best of all like a Megaray, T Rex Active UV, or Solar Glo. You don't want to use MVBs on a small tank,though, because they produce more heat than their incandescent same wattage counterparts. They are great because they work as both the UVB and basking bulb.
