At the moment, LEDs on PCB aka Quantum Boards gives you the best efficiency aka more lights per watts. For your 5ft height, they are perfect as they are flat and around a few cm thick with heatsink. Spread will be great. They require a small amount of DIY work. Most boards are squarish and should work well in your tent. You can dim them however you wish too. Best bang for the buck imo. Just do some reading and head over to Alibaba if you wanna save $. Otherwise, I'm already seeing rebranded QB vendors on AFN. Go to them for advice!
