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.
, 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
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 .
