Check this out, it has tests on the particular bulb that you have, the 300 watt Osram UV (Ultra Vitalux) ReptileUV Mega-Ray Mercury Vapour Lamps for Reptiles - Test Report UV Guide 2006. It has a few graphs and tables explaining how much that bulb puts off and how much is normal(natural sunlight) etcBut surely no more than the sun would in a hot country? Isn't this stuff also good for us in mediocre doses? Vitamin D, all that shit?
I don't know, these are genuine questions. I'm yet to look into them properly.
lol when the bulb is new it emitts 2000 uw/cm2 at 12"(but it declines rapidly the first 90hrs), you don't really want to go higher than 500 uw/cm2. But read that link it will show it all...
