Bro, noone on this board with any real smarts will tell you that you can have too much light.
Too much heat from lights, yes.
Too much light? HELL NO!!!!!!!!!
The more light you can cram in that setup the better.......but remember it limits your growth potential with your smaller and smaller size of cabinet.
If you have tote boxes why dont you cut the bottom out of one and stack in on another one and hang lights everywhere in that? It would be the easiest thing in the world to be stealth and alot bigger than what youre doing.
Just get a carpet/utility knife and cut out some of the very bottom (carefully leaving the rounded or like 1" of the bottom perimeter for structure and to grap the false top)
Then do the same to the top of the bottom one..........glue together and you have a 3 foot tall 2 foot wide and 1 foot deep (Im guessing youre using little totes) "cabinet"
Line it with panda double thick (help keep it from glowing at night) and hang your lights.
Ive seen a cat do something similiar in a single big tote.......here and in person. It can be done with pleasant (mind you not mind boggling) results.
