[split] uvb lights still emit UV ?

[jaketheskate]

I was wondering this, do UVB lights emit UVB as long as they turn on? Or do they run out eventually, even though they produce light?

Should be fine. And they don't all stop emitting UV. I recently got a UV light meter and tested a four year old MVB bulb that shouldn't even work anymore. I was shocked when it was producing UVB levels equal to the sun on a summer day, and I was measuring through a screen too.

With all the conjecture and opinions on UV bulbs for reptiles, the only way to know what you have is to get a light meter and measure YOUR bulb output in YOUR enclosure. I mostly use the sun to meet my reptiles UV needs, but if I lived in a frozen climate and was dependent upon indoor UV, I would not even attempt it without a good UV meter.

Which make of bulb would you recommend? I need an actual bulb rather than a tube and I know coil bulbs are a no no but I'm stuck on which make is best and would hate to choose wrong on such an important element!

I recommend the 6.5 model.
