I am in the process of setting up a new canopy to support MH/VHO and moon lighting for my tank. I was looking at a HQI Doubleded Reflector and was seeing these warnings:
<Quote>
Do not mount "double ended" HQI type bulbs without a UV filtering glass shield!! This bulb will put out UV radiation which can damage your eyes and skin, as well as your animals in the tank. The bulb MUST BE burned behind a protective glass sheet.

That just struck me as odd. Am I right in thinking this is no different than the UV the sun gives out? If I am exposed to the bulb we are talking sunburn and in 20 years of constant exposure a little skin cancer?
Has anybody here used these kinds of bulbs/reflectors before? What did you think of them?
Oh, just for interest I have a 75G tank and am thinking of two reflectors for HM, two VHO bulbs and a moon light LED setup. Still haven't made up my mind if I want to do 250w or 150w. Thinking 250w as a tank upgrade has appeared in the fringes of my mind. Thinking the 250's would work for the bigger tank as well.
Thanks,
