Hey @dbrn32
How are you doing? I have a fast question on our last project.
We decided to use:
9 x BXEB-L0560Z-35E2000-C-B3 on hlg-185h-c1050a
7 x BXEB-L0560Z-50E2000-C-B3 on lpc-100-700
I saw that Digikey has in stock the eb 3 now, precisely:
BXEB-L0590U-35E1500-C-C3
BXEB-L0590U-50E1500-C-C3
Should I use the same number of strips on the same drivers? Will I get a higher efficiency with the eb 3 (1500 lm) or should I use the eb 2 and save some money?
The eb gen3 is more efficient than gen 2. Same driver and configuration should work as long as you getting same part in newer generation. The brought out a bunch of new products for gen3 lineup.
Cool! I will go for the latest generation then. Thanks dude.
No problem my friend
@dbrn32 I need to light the other half of my 8x4 tent. How would I do it using the kit @GoodMafia has just posted
You would need about three of these to flower a 4x4 @Davyg. May make more sense to use larger drivers and longer strips.
@dbrn32 I take it these are mounted on a heatsink of sorts. When you say longer strips I take it you mean joining two together or are they manufactured in various lengths
They aren’t mounted to heatsinks, you would have to source them separately and assemble. You could assemble strips back to back or end to end so to speak. The part number you listed is for 560mm strips, same strip is available in 1120mm version.
Ah ha, I’m on it now. Just need to do a bit of shopping. 3 @ 1120 plus heatsinks to suit then an HLG dimmable driver to match the current draw and a frame to hold it all together 
For a 4x4 flowering, I would do two hlg-240h-c1050a with 5 1120mm eb gen3 on each driver, that is kind of a bare minimum setup.
Imo these strips not the most convenient if you have measurements any less that 48" either. They are 44" long, and usually need another inch or two to frame them out. If you put in tent and walls suck in they can be damaged.
I have 5 feet to play with as I would run them down the length of my tent. If that would be a bare minimum setup, how would you beef it up @dbrn32
Going with a third driver if using those. I would have to sit down and compare pricing closely on other setups.
It would be interesting to see how it compares to other builds. I can get three QB260’s for £700 or $920.
Hello again my friend @dbrn32
I need your opinion to make a decision between 3 options of the eb gen3 that I found for a flowering space of 2x6; the idea is to build 2 fixtures.
Using BXEB-L0590U-35E1500-C-C3 strips
https://www.digikey.it/product-detail/en/BXEB-L0590U-35E1500-C-C3/976-BXEB-L0590U-35E1500-C-C3-ND/10279848/?itemSeq=347192285
This version is the Slim one having a 12.7mm width. To get a better coverage, maybe I should use:
14 x L0590U-35E1500-C-C3 on hlg-185h-c700a
instead of
9 x BXEB-L0590U-35E1500-C-C3 on hlg-185h-c1050a
The above are 2 options.
Using BXEB-L0560Z-35E4000-C-D3
https://www.digikey.it/product-detail/en/bridgelux/BXEB-L0560Z-35E4000-C-D3/976-BXEB-L0560Z-35E4000-C-D3-ND/13181795
This version is the High Output having a standard 24mm width and tested on 1.4A
As you taught me, here I should use:
7 x BXEB-L0560Z-35E4000-C-D3 on hlg-185h-c1400a
Can you help me to choose between these options taking in consideration Efficiency, Heat and Coverage please?
In this scenario running 14 strips will be more efficient and provide more coverage. When something is efficient that means less heat waste. So the 700ma build would be superior, the cost of the additional strips would also be more expensive if cost is an issue.
Now when you compare 14 strips at 700ma vs 7 of the high output strips, the efficiency and total amount of light is about the same. But still easier to get more balanced coverage with having twice as many strips using the 700ma build.
Good to know this new info.
Cost will be 50 bucks more. It will be affordable for a higher end product. Thanks my friend for your help.
Happy I could help, keep me posted!
Sure my friend! I will post pics when I start building them.
