UVb an experiment

[DreadedHermie]

Hi Apollonia.... I think the glass lens will block some of the UVB light but not much, maybe 5% at best....I think I read that somewhere before...:thumbsup:

That seems about right, at least for this one.

Here's my "UV transmission test chamber" (lol). :tin foil hat:

I put some eyeglasses (Transitions, UV photochromatic) inside the bucket. The glass over the top is the lens from an Easycool 6.

The eyeglasses darkened right up. They don't do this if you use automotive window glass (blocks UV) as your filter. So, the Easycool lens must be passing the UV.
