Hi!, it would be interesting, to list, also the PAR Watts!

or prob more useful is at wall watts per square foot and/or estimated PAR W when light and driver efficiency are combined, as were guessing in a lot of cases. i amended my first post you guys feel free to do the same. i used some guesstimate system efficiencies for DE HPS and LEC

so far

i must say thats mighty impressive numbers there tenthirty! and i love the clean install on that driver board!

Output watts is 350, Vero29v1 3000K 80 CRI at .7 amps I was assuming for some reason the efficiency is 42%, but after looking over the datasheet it looks like 39% is more accurate, so 136 par watts over 10 feet,13.6 par w/swft. It's the strain!, and an ideal (trouble free) cycle.

GPW: 1.48 (what low efficiency drivers does to yield figures)
GPoutputW: 1.68 (Old Vero's still kickin')
GPparW: 4.3 (All me)... and the plants.
hypothetical GPW: 1.57 (If I had been using HLG-185H-C700s)
hypothetical GPW: 1.83 (If I had been using HLG-240H-C2100s and CXB3590 CD at 2.1 amps)

Wow i wouldnt expect a thai to yield like that

light source: Osram zelion 3x2 (125w), 2nd run

strain: 3 sensi white label NL photo/fem, 12/12 from seed and still performed as usual(100-115day harvest window)

distance: tried to keep it at least 20 inches away due to heavy 660nm output(1180umol/s @ 24 " center point), ran out of height

yield: 251g +/- dry, no popcorn shit.......played a balancing act with the containers, #s jumping around 243-256g, took the pic when it was steady but still :wink:

https://www.rollitup.org/t/testing-osrams-150w-horticultural-led-fixture-v1-monochromatic-dream-or-nightmare.867782/

wanted to do a third run to see if repeatable, but my eyes couldn't take the spectra anymore, boxed up now and ready to go back to the US distributor, if they ever send me a return label......ha

BOBBY_G · Feb 28, 2016

are those really $900 for 125W? thats absurd

the california lightworks osram panels are like $400 for 170W and have a whiter spectrum

they use the osram "SSL", im not sure how that compares to the chips in yours

BOBBY_G · Feb 28, 2016

that is 2 gpw tho!

no veg? just 12/12 from seed... i mean u still had over 3 months till harvest.. but.. i guess w/ a panel designed specifically for flowering who needs veg?

It's built by O$ram, they think very highly of themselves, yeah pricing is stupid, BOM/R&D/Certs was high but still........distributors tried/pleaded to lower price, germans are stubborn and now their stockpiles of them not moving.

efficient "white" cobs can do these #s or better? in the same setup IMO (30 gal rols microbed /high co2/nl strain)

CLW never mentions their ssl 80 bins

BOBBY_G · Feb 28, 2016

they say 'top bin' in their advertising which of course is relative to the market at a given time and open to a lot of stretching of the story as well.

i think youre gonna top out at around 2 GPW like you did, but you can build a REALLY efficient 125W cob array for 1/3 of the cost of that fixture....

Will the osram split into three panels? Maybe run a bar of cobs in between or around the osram.

If you want to buy the supraspl cob setup just plug and play go to www.ihlite.com and check it out.

These are all hand made in California.
They have a few systems already built ready to go.

I'm really stoned......

is that affilaited with supra or is that just a ripoff of the popular 4x1400 ma setup

Well, I ripped it from here too- but I'm happy to give credit where it's due.

tenthirty · Feb 29, 2016

It's totally a ripoff/copy of supra's design with some improvements. These things are a lot of work to build.
