The Dope Shed.

[Rootbound]

Some shots of the Purple Storm with individual scrogs on Day 24. A couple of these are growing strong enough to push the tomato cage out of the coco. Completely filled this 4x4, which only really has reflective walls on 2 sides. I would expect better yields in a tent. This run is a test of the HLG 550 clone that I put together. So far they are crushing. The canopy depth is about 18'' with plants a little over 3' tall. Keeping the light around 14-16'' off the top of the canopy, and getting good penetration.

Looking for 150g plants if things keep going well. Glad I've got these isolated for a test to see whats good with the quantum boards.

Veg ready to take the torch and run the race.

How much did your hlg 4x288 cost you to build? Looking to replace my cob set up in flower with 4 x 288.

I think it was right around $550, for the driver, boards, and heat sinks. I reused the angle aluminum from a previous build. Had a couple of good grows with it, produces quality for sure. Love the 3000k spectrum.

What cobs are you looking to replace? Have you seen these wavy boards?
I almost bought a few the other day, but I really need to buy a par meter before I invest in more lighting. The ones that interest me the most have a mix of 2700k and 4000k on the same boards.

I looked at them but they are 100 watt boards I believe. The 2 hlg qb 288 panel I have in veg runs at 285 watts. Would like to put 2 of these in flower for 570 watts. I currently am running a plc420 3590 cob fixture that runs at 420 watts in flower. I like it but I love the QB boards, especially in a tent.

instead of the boards
why dont you build Samsung strips F series 2' or 4'
keep adding strips till you get the wattage you want with a CV driver
they use the Samsung s6 chip

I dont have the time for a build from scratch using strips. Just was wondering how much he saved.

not gonna argue but....would take as long as hooking up a "Quantum Board"
unless you are getting pre-built boards with driver and all that already connected?
I guess time IS money

I put in 60+ hrs at work normally, yes time is $$$. The qb fixture I have now was prebuilt, but looking at it, it would only of took 10 minutes to slap together as the heatsink is the frame. Just weighing my options.

I like this idea Wisher. Been eying the strip builds lately and seems like its cheaper and better too. Do you know where to source the strips?

You'll have a better spread potential and power with the QBs. Seems like a winning combo.

22" strip

4' strip
https://www.digikey.com/product-det...uctor-inc/SI-B8VZ91B20WW/1510-2229-ND/6676693

with this 4' strip
1 strip ran @75% power
will run 128.8w with an HLG-150h-48 that strip will be putting out 21,312 lumens
now I know we dont count lumens but for output purposes

4 of those strips would produce 85,000 lumens at 500w that is on par with a 600w Eye Horti super HPS

with the 2' strips

8 strips @531w will equal lumen output of a 600w eye horti hps

That's pretty awesome info Wisher. Thanks for sharing. I want to build one now...

where are you getting those numbers bro ? looking at the data sheets they say the 4 ft strip is around 17340 lm at the test current of 2.25 amps.generally we under drive diy leds to gain eff and try to bump our lpw up around 180 to 190lm per watt.you would have to overdrive the strip to reach anything close to 20k lm and would then be down in the mid 150 lpw to 160 lpw maybe im missing something in there idk ? if they werent 48 bucks each i would grab the last 2 strips and do some tests with my par meter,got me curious on these till i saw the sheets.but like i said maybe im missing something lol

Nice point Six. Just looked at the data sheet, says 185 l/w at the max output 48.3v. So efficiency gets better whit higher current. Says 19075 lumens. I've noticed people are running them at 48 volts too, so they may be a bit different than what we're used too. Seems crazy that its producing higher efficacy at higher voltage, but thats what I'm reading.

correct
these are supposed to be driven on volts
much different than a cob setup where we underdrive
these should be drivin at there max voltage so a constantant voltage driver is used
not a constant current
@sixstring
I got my numbers from a site where they actually ran all the numbers on each strip and tested them
then input the data into a calculator so you can determin what you need
I do agree the data dosnt match the specs which also dont match the actual data sheet
odd

Yeah these have always kinda confused me, probably why I never tried a build with them

yeah me as well

but yeah once you understand it completely it is way easier than series
I also have seen these pushed hard
and they just keep going forward
same concept as quantom or chill led
I am gonna build one for a small space and see where it gets me
pretty cheap
$300.00 for about 55,000 lumens
last 3-5 years of constant blooming
cant beat that

 

[sixstring]

No I fully understand the parallel wiring part,it's the data sheets and people claiming they do better at higher wattage than they do driven soft.if it's anything like the Samsung lm561 the sweet spot is way down low at almost 200lpw but even at 1 amp they hit high 170 low 180lpw.only thing I have seen dominating at high power is the high volt vero29 69v cob.so if these data sheets are wrong can ya point me to some tests that show actual numbers

@CallmeTex sorry man,just realized we are going off on these bridglux strips in your thread,let me know if ya want it cleaned up maybe we can start a topic on it elsewhere

Lets keep it going. I'm interested in building with mid ranged strips both for cannabis and non-canna related plants. Looks like they would be killer for growing veggie starts on a rolling shelf. Any thing Dope or LED related is welcome here...

I agree
I might be getting tge 4' x2
see what it can do in a 2x4 space
