Will Mold Fluorescent under Leak Lamp

I was wondering if Mold would Fluorescent under the UV lamps you use with the Dye Leak detection systems.

Yes it will be brighter just like a lot of materials.

Thanks, I'll try to borrow one. I saw the safety person today in the parking on the way out to a call. Boss had taken pictures of an Air Handler, that is really bad. Couldn't see it on their Laptop, I'm like WTF, also I missed my invite to the meeting. Had time to think about it and things just don't add up. You can see the mold on my Cell Phone pictures, clear as day.
