3,4 and 5........all beautiful bright setups
If heat is an issue I'd go option 5. I think you could also save some $ and use 6x39. The LED strips can act as bulbs 7&8.
5 or 6 for me.
I use a 6x39 over a 36x24 and I can easily say that a 8x39+strips would be overkill and borderline too wide. Agree with Ed that 6x39+strips is purrrrfect.
