cant see why it wouldnt, its got 10-15% efficiency on the CXBs, even at low currents

But only compared to a lower bin 3000K CXB. I think the 3500K CXB CD bin could still outperform the 1825 at it's most efficient 3000K 80CRI model.

sure but why would you compare different CCTs? 3500K will almost always bin higher than 3000K in any series of chips. Malocan's tests had 2700k 90CRI equaling 3500K CXB CD bin. until anyone can demonstrate otherwise, we have to assume than an 1825 will outperform a CXB at any given color

Why not?
What matters is the umol/J and I don't care which CCT or even which brand gives me the best umol/J/$ ratio.

I would not consider myself a Cree zealot but i dont have to assume anything at all from one guy's test of one chip.
I appreciate the data but there is a lot of gun-jumping going on around here.
Im going to wait for a few more builds and a few more documented start to finish grows with the citizens before I believe anything anyone's saying about performance.
The burden of proof is not on Cree, its on Citizen and so far they look promising....nothing more.

Thanks for posting. I have the same question. What parts exactly are needed? Flowering for me too. I have a room but 4x4 works for me.

me neither. we have 3 out of 3 people independently verifying here though, with the same results. and nobody demonstrating the opposite
burden of proof is on nobody... its data for people to digest as they see fit. at this point what we know is that the data citi presents seems to be pretty accurate (if not understated, in fact)

How many clu0481818 would I need for a 9foot x 10 foot room I know what I would need if I were to go with cree just not sure what I would need for citizen cobs they confuse me lol

depends what current you are running them at
1.4-2.8A = about the same
less than 1.4A - a few more citis(5%?)
over 2.8A - a few less citis (5%?)
in practicality 1818 and 3590 are almost identical in efficiency from 50-100W

OK thank you . When will you be getting more of the 1818s?

not in the same color. thats his point. in jorge's eyes 2700 90 cri is a superior spectrum and the 1825 still matches the par output of the 3500k cree.A 2700 90 cri cree would not have the same output
1818s are a closer match for 3590s

most is in stock, rest due in ~4 weeks
i have no orders in for anything but 2700-4000K in 80 and 90 cri,
