There are MVB bulbs which give heat, light and uvb, but these have been found to dry and damage tort shells so uvb tubes are mostly recommeneded now. Don't buy any coiled or cfl type bulbs as these can damage tort eyes.Ok. So the basking bulb and UV light are different? I would’ve thought that would be one light. Is there a place with recommendations for those types of setups, including UV bulbs? I ordered a double dome light for reptiles as recommended by the pet supply place and feel like that’s probably going to go back, based on this information. Many thanks!
