Hi everyone, I’m new to growing tomatoes from seed indoors. With that being said I was curious if anyone had any tips or suggestions on how far my light should be from seedlings to prevent damaging them? Thanks in advance, picture of light attached!

Two feet I’d say
I would download a free app called Photone and measure the PPFD (usable light for plants) hitting the canopy. I shoot for 300 PPFD and leave my lights on for 16 hours a day.
I sense those are older lights and hard to say the light quality and how much power it would consume vs newer far more efficient lights with more usable plant light.
