magnum 357 led grow lights. how many do i need to cover a 4ft x 4ft grow room?

hi guys, i'm thinking of investing in some magnum 357 led grow lights. could anyone tell me if 2 lights would be enough to cover either a 3ft x 4ft (12sq ft) or 4ft x 4ft (16sq ft). i can only really afford 2 lights and i dont want to start a grow if i dont have enough light to finish. from what i have read 2 should do the job but if antone has ant experience with these lights it would give me peace of mind if i could see some actual results before i shell out $1500.

If you wait like a week, they're coming out with all new panels, and their larger one is said to cover 4 x 4. It costs $1000 and free shipping. I may be getting one also

sounds interesting. i'll definatly wait and take a look before i buy. thanks for the advice.

2 should cover that space. Make sure you have plenty of reflective properties surrounding the area
