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.

Not a bad guess. I'm thinking some minor scorching is what happened here. Not on
the thick rugosas micro toms, but some of my micro sunflowers jumped up a bit
beyond micro and have some burn. I'm keeping all starts at 5-7inch, not 2-4.
