Height of my light

Hey guess. I’m curious about the distance my light should be from my seedlings. I have just 2 seedlings currently. Just under 3 weeks old.
I’ll post a pic of one of them below. It seems healthy. But I don’t know if I could benefit from lowering my lights or not yet.
I use a Viperspectra V900 Reflector light.

This exact one

The light is about 43” up right now. Do you think this is a good spot still? Or can I lower it.

Sure can. It’s a 390w light and you can run it at 24”. But they’re not stretching so you can leave it where it’s at. I would try and bump up the humidity though. Try and get it to around 65%
