I have an old "eprom eraser". Basically a bare 4W germicidal bulb. One of those blue-glowing UVB mercury fluorescent lights.

Do you have any idea what sort of intensity the frogs need? 4W is one of the smaller bulbs. is this something i could use maybe by affixing this tube to my hood? this is the sort of light you aren't really supposed to look at; It's 254nm uv. i worry it would erase them or smoething. But maybe using this thing would get me out of buying a light for my frogs.
