infrared bulb uv output
 

I just got one of these to heat my ferm chamber. While it bills itself as an infrared lamp, it puts out a ton of visible light. Which of course makes me worry about UV output as well. Anyone have any clues as to how to find out the UV output of this puppy?

Thanks.

Ok, read a few other threads and just threw a black shirt on my carboy. I've got a few bottles in there as well, but they are of course all brown, so I think the consensus it they should be fine. The light seems to work great as a heater, now to just keep my eyes on it and make sure it doesn't burst into flames.

I used to use one of these which don't put out any light. I have since switched to a very small space heater. This works better for me because my ferm chamber is in a unheated garage.
