If you have LED light, you definately should increase the light level to 400 ppfd! 150 is much to low.

150μmol/m².s is very low to me. You can start increasing gradually to reach 400μmol/m².s

Looking at your pics I'd say the light height is decent where your at.

What are you checking with? How does the plant look? What's the light manufacturers recommendation?

Light intensity? Should I dim?
I'm having a light-science question. I have 5 bulbs, 11w each, total 55w. I know this is not much but anyway. Should I dim the lights for seedlings even If I have this low setup? I mean, does light intensity affects seedlings' health? Or 55w can work on a maximum level?
