On the matter of LED UV

Only ones I've seen are ... 7027539682

From what I've read, the Zoo Med ReptiSun LED UVB Terrarium Hood has a bank of LED's built in that add bright white light ONLY , and it's necessary to install a T5HO UVB tube in the hood to provide UVA & UVB.

I've seen these too ... 1083122666 which I wouldn't touch with a barge pole .... I suspect the UVA band emitted is very narrow and it will not be produce sufficient UVA flux (microW UVA / across the entire UVA spectrum).

Note UVA 400 nm - 320 nm. UVB 320 nm - 290 nm.
I've seen these ... -1109.html , band of UVA produced = 390-420nm , I'd be concerned about the lack of emission > 390 nm.
and theseΦ20mm-p-963.html
, emission band centred on 365nm , not sure the width of the power spectrum emitted, again likely only +/- 10 to 20 nm.
So you'd likely need a combination the two to get close to a full UVA power spectrum, and then there's the microW UVA / vs distance relationship , I've seen no information on this with these LEDs Apart from
Spot diameter ∮4, irradiation distance 10mm, peak (irradiation intensity) 8000mw / cm2

I am certain UVA and UVB LEDs for reptiles will eventually appear on the market.

Feel free to add to this as you test , in particular if you have Solarmeters and can measure UVI, or microW UVA / vs distance maps and microW UVB / vs distance maps .
