200w dimmable also sound like a great match for the bridgelux v-series v22s for a value play.

They do have that configuration. I can't remember, but think you're international? If yes, then contacting them direct is probably the way to go.
toddtang@@lsdpower.com is my contact.
Here is the data sheet they have.

It is lacking compared to meanwells standards.
They have told me that the dimming specs are identical to meanwell. I have confirmed resistance and pwm.
They provide a very indepth data sheet with the order and I will upload that whole thing when the stock comes in.
They are very good matches with CXB's. That is why we are carry them,very cree focused. But the company has the ability to make many variations.
With that said, not everyone has been put through UL and everything. Some have it, and I know the rest can get it when put through. Meanwell could make a whole bunch of current/voltage combos too, but they would also not be certified, so they don't even bring up the thought.
These 200w in 1.4 and 1.8 will go through UL soon cause they will be in high demand.
Ya, should work well for a few other brands too.
Probably about 3 weeks for new stock of the 50w'ers and the new 200w'ers. We paid for air shipping to get them here as soon as possible because I know many are waiting for them.

Seems like the 2 best options under 1000ma.
I like the 900ma myself...not too much increased build cost, and the gain is there efficiency wise. And can offer low clearance.
Between 700ma or 900ma...what do other people like as a stock option?

Offering something Meanwell doesn't, like 900ma, would be nice.

Ran the numbers for a 3x3 and it's not a big difference in PPFD, 8x3590 @ 700 ma is 580 and 6x3590 @ 900 ma is around 625,both good for a scrog.

Might be good to have both options,you already have two options on the other end,1400 ma and 1800 ma.

150w at 2.1A. But that's because 50% ROI is faster than 56%+, and by the time the earliest ROI comes, we'll want to upgrade to presumably newer more efficient leds.
150w for a pair of cobs designs well also. Could use it in a 2'x2', stretch it to a 2'x3', put a pair in a 3'x3'. Plus over building and drimming is a fairly cheap addition to DIY, and what better way to fight lumen depreciation than with a little crank up of the knob?
When does the efficiency drop off for these drivers? I'm assuming ~50%?

700ma is compatible with a wider range of monos.
cree Royal blues and photo reds have at least a max current of 1000ma. But many of the monos max is 800 or 700 ma.
although I suppose most diy builders won't be supplementing, so maybe it doesn't matter, but I like to fill out the Vf on my light bars.
Other than that I prefer 900ma

I dont think weve seen any data on this yet150w at 2.1A. But that's because 50% ROI is faster than 56%+, and by the time the earliest ROI comes, we'll want to upgrade to presumably newer more efficient leds.

Data on ROI? I'm at $383 for 300w at 50% not counting miscellaneous(scavenged from junk), That's 150par watts, $1.27/wall watt build. Building a 200w at 56% came to $334, $1.67/w, 268w needed for the same 150 par watts, $448 build. $65 more for the same light, -32 watts. $.00384 extra per hour for 32 watts, 16,927 hours to see that extra $65.

That is if cooling cost are not a issue. I cant get heat out of my grow easily so cooling is a road block. Run cooler means more area lite for me.
