I've heard that some of the UVB bulbs are being found to emit massive quantities of UVB and this is harmful to our reptiles. However, what do we use then? I can't use MVB bulbs in most of my tanks, as they are too small. Not to mention the price. What are everyone else' experiences with the fluorescent compact bulbs (Such as reptisun by zoomed or reptiglo by exo terra)? Which ones do you "trust"?
