All these are great suggestions, I don’t know your budget but I have a 3x3 and am shopping for a new LED as well, because I already own a Crecer Lighting panthrx ii mini that is a 320 watt bar style light, but it’s penetration wasn’t quite as deep as say a CMH was in the same space.
But after long hours of research and comparing many lights from Mars Hydro to Growers Choice to HLG and many others now I want to go with an HLG 300L Rspec or possibly an HLG 350R and will use my current LED for my veg area once I get my HLG for flower.
The 300L is a 2.5 x 2.5 to 3 x 3 footprint according to HLG
The 350R is a 3x5 footprint so a bit more rectangle according to HLG
I’d probably rather go a bit overkill with the 350R being 330 watts that’s 36 watts/sq ft in a 3x3 and dim her at first then turn her up as plants adjust than have my corners not lit up enough or not quite enough canopy penetration with the 300L at only 250 watts that puts you at only 27 watts/sq ft in a 3x3
But does that justify an extra $100 price tag? To me I think it does, but if your on a tighter budget consider the mars hydro and maxisun and other options, but if you can afford it I’ve only heard amazing things about HLG, from the lights themselves to the customer service.
Here are the specs of a 300L and 350R in that order from HLGs website :
