IMO go for the best one possible regardless of the price. The thing about lighting is even if the better ones only get you a few more grams, it adds up over 2 or 3 grows and makes it worth it. Plus if you get a low quality one, in the future you'll end up spending the money anyway.

Almoat all Led at 240w will grow great buds. The difference will be the heat, warranty and overall quality and life of the fixture. Probably a good idea to list budget to help ppl suggest a light.

The footprint also needs to be considered for light spread. It does no good to have a light that you can't max out because the middle is burning and the sides get to little. A 2x4 will do best with something designed for that footprint or 2 single lower wattage fixtures IMO.

Well you know what i run 2 spiderfarmer sf1000's. They do a great job for me in a white wallwd closet, no reflective surfaces. Im pretty sure these come close to doimg a 2×4 grow tent just 1 of them. I do wanna upgrade my lighting though to something more commercial grade

Carambola, white rose series. I think they do a fine job for the money and haven't had any issues other than having to snug a couple lil screws on the ballast when I recieved them. They come with 2 ratchet ropes for 1 light. Can order 1 3 or 6 and the 3 and 6 options have rails you can attach the lights to

If its a full grow time light i'd do 3500K if flower 3000K or if it's just for veg then 4000K. I personally got a 3500K with 660nm red for flower.
