Help choosing lighting type for my grow box

I am working on converting a gun cabinet into a stealth grow box. The section that I have divided off for flowering is 35" tall, 20" wide, and 15" deep. I am trying to decide on what lighting setup to use. I have considered a 100w HPS but realized that nobody makes them for growing. That would mean I'd have to create a DIY reflector and fixture, not something that I couldn't do but possibly more trouble than it's worth. My next option is CFL's. I figured if I put 200-250 watts of CFL's in it I could flower about 3-4 plants. I am also looking at T5 fixtures for side lighting or maybe even top lighting. I don't have any experience with LED's, but I am also considering them for supplemental side lighting. I don't plan on buying the cheap Chinese ones though, only high quality. Based on these options and dimensions, what would you recommend for top and side lighting? Total wattage isn't really an issue, I don't mind paying a couple bucks more a month in electricity for a better setup. Heat definitely is a factor, I plan on cooling with 1 or 2 computer fans so having the HPS kind of worries me. I heard that T5's are more efficient and cooler even than CFL's. Is that true? Any information or suggestions are appreciated.

Look up "PLL club" on Google. All I'm sayin'.

Tex: my cloning tent is 2' by 2' and 4' tall and all I'm using is a single 5000K CFL in a spun aluminum hood and socket I bought at The Home Depot. I don't remember how much I paid for it but I'm pretty sure it wasn't over ten or twelve dollars. The hood is about 10 1/2" in diameter and it doesn't get very hot. It works well. I hope that helps.
