about 1-2 inches away, if you can put your hand under the lights and not get burned, then they will be fine at that distance.

No. Lights should not be that close to to germinated seeds or young seedings. 10 inches gradually working to 6. Later you can get down to 2 inches.

yep, as illegalsmile said-keep them further when they are young weak seedlings, like 4-6 inches away, and then keep them an inch away.

Ah, thanks for correcting me guys. My bad.
Some of my young sprouts seem to be doing great at about 2 inches however.
Maybe I'm lucky? Haha.

My little guys do great and I keep the lights about 1 to 2 inches away. I dont want them getting too tall so thats why I go closer, I also keep a fan blowing on the plants while the lights are on to keep the heat away from the plants.
