- I use Megaray MVBs (Mercury Vapor Bulbs). I'm a big fan of MVBs. If you use one keep in mind it can't be dimmed, should be allowed to cool off before turning it back on, and it needs to be in a fitting that provides lots of airflow (wire dome, not closed ceramic dome).
- I don't use UVB for most of my skinks, but I have 2 'play tanks' with MVB bulbs for the skinks to spend some time in, and my Monkey Tails have a MVB to themselves.
- - - I supplement my food with calcium + D3 to make up for the lack of UVB.
- Zoo Med and Exo-Terra make fine UVB bulbs. Remember that UVB bulbs tend to stop producing UVB after about 6 months, but still produce normal light. MVB bulbs produce UVB until they burn out.
- By screen top do you mean flyscreen-like or hardware-mesh-like? Screens like flyscreen block almost all UVB, making the bulb pointless. Hardware mesh (1/4+ inch holes) lets the UVB in
