I've seen those. $370 for the 250w version. And it is a Veg light. 4000K or 5000K. And you still don't have a reflector. +$25.

I like the self contained aspect of these high bay lights, but, so expensive. And we don't need to pay for all that.

Well, 160W version has 18000lm. This could mean that they're 30-35% efficient. It's comparable to A51 efficiency and much cheaper...4000K is not exactly grower's choice for flowering but I think it'd do the work.

cxb<cxa<cxb v2...............always liked the design though, if they update the chips not a bad buy as alesh pointed out

I was wondering what cxb cobs they use?

I will say that so far 4000k is whooping 3k. Granted they are differnt wattage lights...the 4k being higher wattage. But their coverage reflects their wattage. The bud development is better and bigger on the 4k. Only half way so still lots to see towards the end. But is impressing/surprising me nicely so far. 3500k is on my mind next

Edit: I have 80CRI 4k's. That is the key I believe.

You know it. A few of us have been preaching it for years(AT guys practice it too ), and the cooler temps come in higher bins.
