On the matter of LED UV

[TOPIC AUTO-LOCKED DUE TO INACTIVITY]

Only ones I've seen are http://vi.raptor.ebaydesc.com/ws/eBayIS ... 7027539682
these DO NOT EMIT UVA or UVB.

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 https://www.ebay.com.au/itm/Snake-Turtl ... 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 / sq.cm across the entire UVA spectrum).

Note UVA 400 nm - 320 nm. UVB 320 nm - 290 nm.
I've seen these http://www.ledwv.com/uv/uv-high-power-l ... -1109.html , band of UVA produced = 390-420nm , I'd be concerned about the lack of emission > 390 nm.
and these
http://www.ledwv.com/uv/uv-led-365nm-3w-Φ20mm-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 / sq.cm 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 / sq.cm vs distance maps and microW UVB / sq.cm vs distance maps .
