Always wear protection 
but seriously even the reflection will mess up your eyes I’ve had headaches from it when I thought just using my hand was enough to block it.
Anywho, as long as u doesn’t go out and pay $150 for floros u good.
My 2x2 is osram mix efficient but only 60w and plants were burning, raised 16" and plants are still squat.
So at 100w raise it all way up to 200 par specs to be safe and watch the seedlings.

On yeah. I will definitely raise my lights if they stress out.
You know. What I think it is, is that these people who make these lights just started doing so in my opinion because they are really too cheap…

I just ordered 3 of these for a 2x4 150w ea figure all 3 dimmed to 80% or so should absolutely kill it.

Nice lights! I have some Qb96’s that I need to put together for my 4x4. I bet a qb96 or two would rock a 2x2.

Yeah! I got two of the QB96 when they were clearing them out recently and wired them up to an HLG-320H-54B spaced out about 18" on the fixture, to light up my 3x4’ veg tent for either transition or flowering

They are damn good lights! I’m very happy with them. Shit the drivers weigh a pound I bet. Out of aluminum too. I honestly don’t understand how they do it especially with Samsung leds. It’s called mass production I think lol

Well hell I wouldn’t exactly call something with Samsung Diodes and a meanwell driver a knockoff.
Those are top components and that’s what I’d want in an LED light anyway.
