UVB LED

[Kaizen]

Not that I’ll be using it for my chamily, but I picked up an LED, that purports to put out uvb. Whether or not this uvb is in the sweet spot (~295nm), I don’t know. It might even be putting out UVC. Anyways, here’s the pic:

Just answered one of my own questions, and raised another: here’s another pic showing the uvb range is 305-315. That’s a little outside the sweet spot, but might still be useful? Weird how my solar meter registered it though. I thought they were designed to be most sensitive to the uvb wavelengths responsible for d3 synthesis. Hmm

290-315 is the sweet spot(295-297 is peak production) for bones. So could be that its putting out some bone growth, and then bleeding up into the UVA zone. Thats alot better vs bleeding into UVC.

And for homework(and america online netscape flashbacks)....

Still can get a UVC test kit.
