About 4-6" or they will stretch a lot more than you want

As close as possible, so long as they won’t grow into them while you’re away.

That's ok to start with I guess.
The main issue is too make sure the temps aren't too much at the top of the plants.
With day-old seedlings I like to start slow that's all.
As for myself, I have a Quad T-5 bulb fixture in which use a pair of Zoo Med 6,500K and 10,000K spectrum bulbs
at 54 watt each. I purchased them at a local Saltwater aquarium Fish store and like using this spectrum mixture.

I start off a little high with all lights and work my way closer over time.
I find this reduces their sunburn stress.

great looking seedlings Pinball wizard. in pic 1 what are the cups sitting on
it's just some plastic ceiling light fixture, ceiling scrape from work, makes for easy drainage
I use it on the bottom of the flower room, too

Always with these tubes try to keep em as close as the babies will tolerate! I use the back if my hand to discern heat temp of said t5.........in my experiance these bulbs aren't powerful enough to damage seedlings.....if you have twenty seedlings I can understand 300w of t5......but if your germinating from seeds you shouldn't need anything more than 2 54w 6400k tubes for them in my opinion. Wanna see brutalized seedlings? Give a newb a screw in LED that's got some decent lumens lmao! I wish u the best

2.5 probably for seedlings under 315w and reducing down to flower.. for flower its around 18-24" but measuring 315s with a par meter makes em look like a waste of money.
315s have a horrible spread unless mounted in a vertical fixture.
Nothing beats 5k samsung solstrips for me..
Yes, I agree with Rab since they are fluorescent tubes (cool or warm), you can get them close without burning the plant. I prefer not much stretch, but others, it works for them. When I had a cabinet it would range between 4"-12" in veg stage, closer (4"-6")and side fluoros during bloom.
