Personnaly, i don't favor MV bulbs at all. I have heard many problems, wheter it be reproductive problems, and even eye problems associated with MV bulbs. Initially people were excited, buying the MV bulbs when it was released and was all the rage, but i hear there are less people using them these day. I've perosonally had problems using overly high UV lights. My chameleon went almost blind in one eye when i first tried a new bulb, but since changing it, she has regain her vision.



Now some people might had success with their high UV lamps, but the fact that its success rate is not even close to 80%, i'd personaly stay away from it. I use to wonder wheter they'd be any difference using an 8.0 and a 5.0 bulb. I thought to myself, "the sun is much stronger than an 8.0 or even an 11.0, so heck...it should be a problem." but then, why would the packaging on the lights say "dessert" or " tropical". Anyway, i changed all my lights to 8.0's, and some reproductinve problems have occured in the females that were under 8.0's, as opposed to the ones that are under 5.0's. I am not sure if there is any relation here, but this discovery iscertainly worth more looking into.



So, altough lots of people have had success using high Uv bulbs, there are quite a number of people who havn't, even well establish breeders. SO untill they make a better product, i shall refrain from using one unless i need to cure MBD.
