You can get a MVB Power Sun or Mega Ray but they are spendy- place unobstructed per the wattage being used -- 80 120 or 160 I believe is what they come -- you need to watch surface basking temps w/ these bulbs as they are great for heat and can be used for a short time as they need to be changed out in 6 months -- the UVB wears out -- by then you can have your long tube fixture by then - we always recommend a back up long tube fixture when using the MVB's
