Anyone ever try one of the Exo-Terra UVB 200 CFL bulbs? Says it provides UVB up to 30 inches away. Right now I'm using the UVB 150 on my bearded dragon, and the UVB 100 on my chameleon. Was thinking about changing to the UVB 200 for my bearded dragon and the UVB 150 for my chameleon next time I have to do the 6 month change. Thanks.
