If thats a 4 foot wide tent the light is at least 2 feet from the top of the plants if not more from looking at that picture unless you raised it for the picture. Have you actually measured it with a tape? I would run it around 12 inches unless I saw heat stress. You just have to make sure the light is covering the whole 4 x 4 area. Watch the shade line on side of your tent and lower it down until it gets close to the outside colas or your desired height.
I have marked your shade line and how far up your tent it is. The circled area is all wasted light for an example that could be going to the plant. Just some tips that may increase your yields.
You will know if its to close. You will start to see the ridges on the fan leaves curl up. I usually let this happen as long as its not bad and not burning the plant personally. Ive ran 600 watt cool tubes 6 inches from colas before with only mild bleaching on the very tip.
