My company is looking for this board to retrofit laboratory workstation lighting. Must be NW. Please PM meNarrow and longer boards. 3-4 inches wide 24 inches long. Still In Design phase and will take 2 months.
@muleface suggested 3x3 boards.
Don't know what batman is using.

Feel free to throw any suggestions.
[QUOTE="robincnn, post: 13257145 Limited 4000K and 5000K will be available in 2-3 weeks.[/QUOTE]My homie who I made hip to these cool QB boards will be ordering some very soon. I will be ordering some in about 1 month. Anyone know when the vegging spectrum set up is coming? Thanks.
so much info buried in this thread.almost be nice to take all of stephen's and robin's posts and put them into a new thread on 1 page@Fastslappy
Boards can be wiredin parallel. That way the DC voltage is not too high.

These Molex connectors are rated 9Amps and max 300V

For series connection you can connect up to 2 boards in series. The voltage is higher than parallel, other than that this config works fine too.

However do not connect 3 boards in series. That exceeds connector voltage and i don't like playing with 300+ DC voltage unless I am building a time machine or particle accelerator.
he makes what ?i did but it was goofy as the board was physically in the sphere and absorbing photons and wasnt really relatable to the same data generated with a cob mounted outside the sphere
i was going to do a tent test with QB vs cobs run efficiently (say 1 QB vs 6 cheap cobs like 1212s at 10-15W each on a similar sized heatsink) but thats a whole different setup.
bigger picture is something like:
use sphere to run individual chips
build chips into fixtures
run fixtures in tent (say standard 3x3 gorilla)
develop par mapping of tent (average of 25 points?)
somehow be able to make a correlation between sphere par and umol/J and real world fixture data
thats like a year of work realistically
either that or build a 4-6' fiberglass sphere.
now that i have one i realize theres not much voodoo to it. a sphere is a sphere and you can buy the coating. beyond that its just calibrating your sphere/detector setup with a known nist light source, which is the same process regardless of sphere size.
makes me want to open a light lab its insane what those guys charge for what they do
hey @sixstring2112 when i was in town at the doctors yesterday i toured my friend of a friends shop he has 2 cnc mills a plasma table and a bunch of other toys. he makes these
Where is the driver bro?Good shot of my light, it really doesn't get much cleaner or simpler than this.
Remote.Where is the driver bro?
When is the new new thing coming out? Or QB Board 2.0?Remote.
My 2 cents...get a good LUX meter. That will be about $35. Measure at top of canopy. 25000 LUX to veg and 50000 to flower. 50k is about 750ish ppfd.The only thing I'm not certain on is light height from the top of the canopy. I'm about 12-14 inches but wonder if I should lift it to 18 or so ?
The only fire i can grow in this state are hot peppers lol...had some holiday fun with this quantum build...thanks @robincnn @Growmau5 @greengenes @SupraSPL for the innovation and inspirationView attachment 3868050 /QUOTE]
Yeah that red frame is really sweet and so is the super clean whole build. A really nice shade of red too.what is attached to the side of the driver? is that something for cooling? or is just to make it look symmetrical?
Also, it looks great! Love the red bars
i think could run 2 panels in parallel @ 125 watts each per driver or maybe more at a lower wattage@robincnn @Stephenj37826 what can i do ,if anything with a pair of these drivers (i actually have 4 of these) or do i need to use something different? I have 4 x qb and 4 x heatsinks i want to make something on the higher power side of things.the plan is a square frame build with 4 cobs on the corners and 1 in the center,all of them will be 2700k or 5000k but haven't decided yet which color i will use
