I grow photos and have a 8x4 tent that i reduced to a 4x4 due to heat issues with the MH bulbs. So I plan to buy some quality LED’s and have this one in mind. What do you guys think If I just use the 4x4 setup I will just use one but when I go back to the 8x4 I will use 2.

HLG is having a 25% off sale for 4/20. I would choose an HLG 600 Rspec over the Vivosun. If Vivosun is truly built with LM301h diodes, then it is a good light too, but the 600 is 200 more watts which would be a better choice for a 4x4 (or 2 of them for an 8x4.) The HLG is more expensive, but with 25% off it is comparable on price, plus you get the 200 more watts for each lamp. It can make a difference in a big tent.

I think I would opt for the Spider Farmer SF4000  
Its a little cheaper and probably an overall better light. 450watt
