light meter?

[sharkboy]

What kind of light meters are out there? Is this the same thing as a lux meter? Anyone have any experience with these? Also, where do you find par ratings on bulbs?

Lots of good info here...

Thanks Jim...where in those articles does it talk about the light meters?

[JimD]

Not sure it does, it was more for the par question.

"Also, where do you find par ratings on bulbs?"

What kind of information are you looking for on lux meters? I can tell you that 1 candlepower is equal to 10 lux....

First of all, I really can't find a big selection. The one I keep coming across is made by Milwaukee instruments. I would like to get one to monitor bulbs for replacement purposes.

Thanks so does Apogee make these quantum meters specifically for underwater applications?
