HLG 260 XW or HLG 320 XW for a 3x3?

I was leaning more toward the 260 xw but then I found the 320 XW


Its not like any other 320 I have seen. It’s the same exact board and layout as the 260 but with a larger driver which I assume pushes the lights more to their limit? (Still learning). Will this extra 40-50 Watts (285 vs 320) make a difference or is it negligible? It’s an extra 50$ and I’m trying to decide if it would be worth it.

I assume these are growers lights kits by HLG?
Personally I think 260w is plenty but that's based on my experience with the regular 260w kits over 2x4 spaces.
For $50 extra its up to you and your reasons for purchasing a LED in the first place. If its GPW or saving power or less heat stick with 260, if maxing out your yield maybe shell out for the higher wattage.
Theres folks on here using these or similar efficiency lights running as low as 20w per square foot and having great results. Although they are the minority as most aim for 30w/psf
