COB Manufacturers other than CREE or BRIDGELUX

the more i look at them the more i'm liking the clu046 1818 35k. I could run them at 1.7a and get nearly 80w or run them at 1050 for roughly 50w each, just not sure how efficient they are and if running them soft makes them more efficient or if i'd be better off running them at nominal would be best. I'm not big on running cobs hard and really don't like the idea of going over 100w a chip. I'd rather have a great spread than a few ultra-powerful cobs

I am interested in these cobs as well, hopefully someone has some experience with it

Supra tested them recently and they unfortunately didn't come in as efficient as any of the Cree cxb chips. I was hoping they were more efficient and was gonna try them out until I saw the numbers on them!
I'm not expecting them to be more efficient, I just want something decent. I currently have Vero 18, although i haven't assembled the light yet. If they were comparable to the veros then I would be happy.
Honestly not much is gonna compete with the cxb3590s, and if there was a cob more efficient I'm sure it would cost even more. I just want more options for cobs that AREN't as expensive as the cxb series to give more flexibility in builds.

I was looking at the vero18 also, and liked the fact that I can run up to 12 off of my current drivers. I like the idea of running more chips softly for maximizing efficiency and spread of light. In my opinion several different points of light ran soft vs one point ran hard will probably give you better results. Also they don't require huge and heavy, cumbersome heat sinks to get the job done which means a lighter finished product. I still can't decide on what heat sinks I want to use for my CXB3590s, I can save a bunch going with CPU sinks, but would then have 16 different fans to power! I guess it will at least look clean...I hope!

I go for this...16 individual panel with fan over a 4x4...I will have to build a "screen" to hold the 16 hs...it will be almost as large as the growbox...same for my 3.5x3.5...but 12 cob @1400mA and I will watch what happen and see if I go with 1050mA...or should I go for 1050mA now to save money on drivers...I will always find a way to use it or sell it!??!

I have some being delivered before Chinese new year(note to anyone buying from China, orders not in stock and not placed on China before the end of this week may not be delivered before end Feb, just saying, China closes basically for all of Feb) looking for some testers for this, Supra, anyone??

This is exactly why I think running the 100W CXB3590 at 50W is a really nice sweet spot. High efficiency and loads of spread is a great combination, to the point that higher wattage chips don't strike me as a better option. Any initial deficiency in intensity can easily be made up in numbers, which naturally enough leads to even better light distribution, aka spread.
I'm not seeing a downside here.
Moving on to second order implications, better efficiency means lower HVAC costs, both in terms of installed capacity and running cost over time. These two savings should not be overlooked when considering a large COB LED array for commercial facility use, as they'll play a direct role in reducing the expected ROI on a high efficiency COB LED installation.
By way of direct example, only 2 Tons of HVAC is calculated to be sufficient for 5kW of CXB3590, running at 56% efficiency.
Oh, snap.

I am open to testing thes, not able to be as as in depth as others can, I am testing other cobs right now from Luminus Devices..CXM-32 in 3000K and 3500K

@ttystikk - I am looking at both penetration and total build cost and how quickly I can put together. If I can take a 250w COB and run them @ 125w to get around 50% efficient, with 4 COBs I can build a 500 watt light. Much simpler than wiring up 20 COB@ 25w or 10 at 50w. I will build you a 700 watt light for $900, how does that sound. I have one if you want.

Interesting. I look forward to seeing what you do with them. Meanwhile, I don't believe my costs are much different than yours and I'm confident the light distribution from more COBs will be better, as well.@ttystikk - I am looking at both penetration and total build cost and how quickly I can put together.

That's the price if I build it for you.^

No news about MW hlg series?
Will you sell some or no? When?

Yes I am working in this. I think what you have here is a problem child. The shipping of COB's relative to their value is easy(Cheap), the reverse applies to drivers. A $50 driver weighs in around 1-2 Kilos so is expensive to ship relative to its base value, I suspect even Jerry finds this which is why he suggests you find a local supplier in your market to support you. Since I am not a MW Disti and cant buy direct I am looking at another supplier of similar products, who I can buy direct from. The range I am considering is
120 Watt, 1050mA, 69-114Vdc output, resistive dim option Price USD48.99 ea
120 Watt, 1400mA, 52-86Vdc output, resistive dim option Price USD48.99 ea
150 Watt, 1050mA, 86-143Vdc output, resistive dim option Price USD51.99 ea
150 Watt, 1400mA, 64-107Vdc output, resistive dim option Price USD51.99 ea
200 Watt, 1400ma, 86-143Vdc output, resistive dim option Price USD59.99 ea
250 Watt, 1400ma, 90-179Vdc output, resistive dim option Price USD63.95 ea
Are these competitive, is this the range. These come in 3 in 1 dim options, just chose resistive as that what you guys seem to use, they also have an IR dim model as well
Let me know

You do also sell heatsinks. 
Those prices are competitive with anyone stateside on octopart assuming the shipping is comparable (and the drivers are as nice as mw). Would love to see the DS for those drivers.
How much would you charge (if you offered it) for a led engine with a cxb3590 "cd" on a mechatronix lsb9980-b? With or without reflectors?
Why aren't you building engines with 3070/3590?

I have a discussion going on about 47-57vdc or 95-115vdc 2.2A led driver from Alibaba and my plan is to use 9x CLU056-1825C1-353M2G2 in 5x5 foot space. One 1000x165x35mm TME RAD-A4291 heat sink to three cobs so its like 60cm2/W and its active cooled by maybe two fans cos its 100cm long piece after all. Totalpower would be 1035-1050 watts.
