Hey man I meant to pass this link on to you. Scroll down and you'll see a PPFD map for the HLG 320 watt kit. It doesn't say R-Spec so it's likely that the tested light was the previously
released V2 model (with LM301B diodes and no Osram Oslon SSL 660nm diodes).
Keep in mind that the 320 watt kit testing was done in open air and the Indoor Frost light testing was done in a tent.
