Just wondering if anyone is using them, and how they are working.

It will grow just fine as long as you are realistic on the amount of space you light up with it.
From what I can see its a 300w light so aim for 2x3ft

What other lights are in your tent? From the pics you out up in your first post, it sure looks like those COBs are white based. What's throwing off the blurple color?

They are white cobs. But look up hollandstar 1800 watt cob led. Amazon I got it. I can’t find out what type of cob the 2 in the centre are. That’s what gives off the other blurple colour? They only come on with the veg switch. But I keep veg and bloom on all the time. They are crazy lights for the price. Also I have 2 of the hollandstar in my tent along with 1 600 watt Ygrow led grow light but it’s gives the same colour as my hps did. Yellow.

A bit late to the party, but i also grabbed one of the 1800w from amazon when they were cheaper. Recommended from a friend.
Tough SOB to find data on, without testing myself. So far so good though. Obviously better choices the more knowledge gained as we go, but for the price, cant complain too much. We'll see how long it lasts.
Ive got 2 plants in a 4'x2'x5' with the one lamp. I find i can get away a but closer than manufacturer's suggestions, but they are pretty intense. Also using both switches for all stages.
Two and a half week into flower on one, about a week behind on the other.
Did you finish up your run? How did it go?
