The lights I have are LED + UV/IR. But now that I think of it, UV/IR would fall outside the PAR spectrum anyways so I guess they are not included in PPFD? What exactly is the benefit of UV/IR - blooming?
But essentially anything to measure PAR is expensive is what I am hearing

Why are you interested in UV and IR?
