If you are growing in a 5x5 tent i would strong advise against getting a panel light. The perimeter of your garden will suck. Bar style lights are much better at light distribution and coverage.
I have 2 of the BO-6500 8 bar. Fits wall to wall in a 4x4 and will be great in a 5x5. The second one i bought i couldn't resist the price. I got the last one on amazon for like 349.99 lol. Crazy. The first one i bought was over 500. I can vouch for them because i own 2 of them.
The bars have a 30 degree rotation ability as well so you can point them to specific targets without affecting the entire light structure. It is dimmable and works flawlessly with the AC Infinity controller 69.
The 8 bar has been sold out for awhile. I got the last one, HOWEVER.....they have smaller lights for pretty cheap. You could buy 2 and daisy chain them together for just as good coverage if not perhaps better. Thats what i would do.
