UVB measuring

[AHBD]

Has anyone seen this ? I linked my own question from the general forum.

Interesting- and doesn't make me all that comfortable with my light choice considering I have a 100w Powersun. I've just been wondering how I would know what/ if any UV the Powersun is putting out considering it's an "all-in-one" light. I assume it has a dual bulb since, when I turn it on, it seems to have two stages.

Thought to post about renting a Solar Meter from someone here.
