I ran that as a veg light specifically back in KC. you can put a blurple light like that lower for sure and just expect a tighter node spacing btw. Those are the hardest lights to burn a plant ive ever used outside warm white t5. Id have vegging plants touch those things sometimes while being lazy, and the only tissue damage would be where it contacted the diode and the immediate area.
if you have a meter or the phone app (and a quality phone), You can read up to about 450 ppfd (maybe 550 with a good angle) from those things, and then as you get closer then 6-8 inches or so, itll actually start to go down as you come out of the footprint of the additional diodes because of their spacing unless youre right on axis with a lense. But even then, they have a diffusor, theyre arent naked like a full spec panel diode
Those are great veg lights and you can be pretty lax with them and play around with distance to control node spacing and stuff without fearing burn too much
