Just got the Vivosun VSFL3000 4 bar grow light
It's actually made for a 3x3, but it also works in the 4x2 with a bit of creative rigging. I am happy with how searingly bright it gets (3000w), and I was able to keep the giant brick of a power supply on top of the tent.
If you have this light, I'd love to know your experience with it in the long term.
