Is this light too close? Too far?

I’m running an auto in my 2x2 on a 100 watt AC Infinity LED light with Samsung diodes, I’ll drop a pic:

My question is, is this too close to the plant? Too far from the plant? I just turned it up to 60% power and raised it a tiny bit, what do you guys think?

18-24 inches should be good. Your plant is looking real good under that light
