Ok once and for all, what would be best to use, Floresecent tubes (which I am now using) or MVB bulbs? This is what I have gathered from research: MVBs Pro - Higher UVB output, provides heat as well, spreads UVB over longer distance. Cons - Can easily overheat the cage, most bulbs don't show the percentage of UVB on their boxes and the same brand can have differing bulbs, overly bright glare, UVB output decays much faster than florescents and need to be replaced very often. Florescents Pro - Doesn't give off too much glaring light, will not overheat, UVB output decays slower than MVB and thus can be used for a few more months. Cons - does not give much heat if needed, UVB is generally less than MVB, and decreases faster over distance. Am I right? And in general, which one is better? Lastly, does a MVB bulb produce the same amount of heat as an incandescent bulb with the same wattage?
