Decision is made for SANlight.
It was between SANlight and australian Highlight 420, which one actualy performs better I dont know but I like compact design which alows more flexibility in the room and SANlight the same as Telos are both upgradeable which means in the future it will cost me much less to keep up to the latest led efficiency. I just ordered upgaded parts for Telos 0006 and cost is around £100 with 2.4μmol/j efficiency from previous 2 μmol/j.
For two 2×4 Gorilla grow tent I will get 4 SANlight Q3W 2nd Gen 120W each, two lights per tent. On recomendation by SANlight for expert mode, preferably dimmed at 80% under typical conditions. Or I may add CO2 and go 100%
One Q3W is ideal for 2×2 so I will have great flexibility, I can use them at optimum in 2×2, 2×4 as well in 4×4 grow space, realy great flexibility.
