i have my new baby gu that i need to go out and buy him a uvb bulb, i dont think a mercury vapor will be good at this point in time as i think it throw off too much heat, hes in a 20 gallon (temporarily) and im using an under the tank heater and a che for heat atm i just have a feeling that a mv will throw off too much heat so really my question is do these small fluorescent bulbs that they say produce uvb actually do so? like this one?
