Vevor took a page out of Samsung/HLG book. the 400w is a lot like the old HLG550. I'd even say they did a better job in some areas, like the remote dimming plus built in dimmer. My lights are the V1 QB288 using the same diodes as this board. I customized mine into Scorpions, before there were Scorpions, and run the driver's remote to save on HVAC for my room. I had no qualms taking a saw to my HLG's but the Vevor is a little too polished to DIY, so I'll be using this in it's own tent. It should be perfect for a 3' x 3'
