Just received new custom 275 watt and 135 watt, 3500k COB, Direct plated Copper, these will have excellent thermal characteristics

We expect the 135 Watt(somewhere between CXB3590 and Vero29) to be around USD23 and the 275 Watt around USD42
Will post PPFD and other data once tested

I'm interested in the smaller ones. I would be down to test, but im planning on building a veg light so it wouldn't be used to flower. I Also see you want test equipment, which I don't have. I would only be able to test for actual grow application so you're probably better off with someone like supra , rahz or gg.

I am interested in getting some of the smaller ones though as soon as you have them available.

Do you know the Vf of the 135 watt ones @700mA
I think sets of 4 would work perfect with my Universal Everline 150 watt drivers

Same here with the drivers. I do have some 700 mA drivers though if these are efficient enough to work with that
