4500 lumens is a lot compared to the typical fluorescent, iirc my 6500 k comes in at 3750 lumens for the pair. The LED lights I bought this year are 4000 lumens. I did have some ?? scorchy leaves ?? on certain brassicas under the LED but don't know for sure if that was the cause.

If it was me, I think I'd set up at least 8 inches to a foot above the seedlings, and wait to see the effects. If they're stretching to get closer, bring it down. But I'm only guessing.
