Anybody ever used Florescent?

I just purchased a t5 florescent and of course it doesn't come with instructions for height recommendations. I have them about 12 inches above plants in a grow tent. Is that an okay distance? Some plants are a few inches taller then others, that's why i have it about 12 inches. I'm trying to find that nice spot for them to grow in to.

Any advise is much appreciated.

It's a 2ft 8 bulb light. Approx 400watts. Plants range from 8-12 inches. I have the light 16 inches above the tallest plant. Is that cool?
I really depends on the tolerance of the plants..sometimes I can put the T5 3 inches above the canopy without creating heat stress others prefer 6 inches. IMO 12 inches with T5 is much too far from canopy.20180313_125600[968].jpg I use T5 HO for supplemental lighting as you can see in pic they are about 4 to 6 inches from top of plant.
