UVB lighting question

[Freddiw123]

So i made a diy wooden 4 ft x 2ft x 2ft cage and I was wondering what wattage of UVB powersun fixture I should get, or if there's a better brand? So like the 100 watt or 160 watt. The cage is built so there is a ramp going to a second level where he can get closer to the lamp

If you're going to stick with an MVB I'd get the 160w and set it about 12'' above the basking area for best results. I prefer to use a T5 tube for UVB so I can set that at 12'' and control heat separately. I use a PAR38 halogen flood light for heating and that is on a dimming thermostat (not necessary, changing height can adjust temps too). This is the UVB light I use http://www.lightyourreptiles.com/22-t-5-ho-fixture-high-output-with-arcadia-d3-12-ho-bulb/
