The DIY video?
The Chilled light used to yield 2 plates or whatever they got is like 660w Think. Could be wrong.

No need to apologize.
Check out their site, I think they come in different sizes.I think these Gen2's are gonna do real well too.

his new lights come in 90w and 175w panels

Thanks. My kit is actually supposed to arrive today!!! I'm so excited.

Got mine I just bought the 90w boards and made my own fixture assembly. I wanted side by side instead of end to end even coverage for my situation 2x4

Nice! I bought the 2-90w board kit for my veg space. I just started growing again after a three year hiatus. Veg lighting is in desperate need of an update. My bloom tent is a 4x4.....and I still have an hps in there. It will be updated this year, but I haven't decided if I will go with boards or COBs yet. I keep vacillating back and forth. I'm sure the design will change every other week until I pull out the charge card and buy the parts.

I am retiring cobs and going with chilled boards for bloom. For veg I am building a 200w 1050ma samsung lm561c s6 bin 3500k/5000k dimmable to 100wNice! I bought the 2-90w board kit for my veg space.

I am drawing just over 300w at the wall on max and 30w on min.

Personally, these boards are best used for flowering. I plan on making the upgrade to 3 like VW did, surrounded by cities or vero29s. full flower ass kicker

I found these fill out the tent with no cob's added. lower heat same light level. I don't have a par meter but I am sure at 300w of chilled gen2 I am more like 400w compared to cobs. For veg I am building a Samsung lm561c S6 bin strip about 250w with 3500K/5000K.

thats quite the statement (for not having a metric)

Yeah. I do it old school. no PAR meters, I just watch the girlz, plus Vitally did a video with GM and gave out the data 2.7umols/w That is all I needed to know as well as higher efficiency numbers than anything I have seen out there to date. :O But you can get a chilkled board and measure it along with some Samsung strips both Constant Voltage and Current. I think you may know the outcomes already. you can do the measuring, I just do what I do best, grow.
2 x 4 = 8SF X .476 = 3.8 boards I am going with 3 boards vs 4 boards.

Vitally numbers below
How Many Boards Do I Need For My Area?
The number of boards you need will depend on what photon flux (light intensity) you are looking to achieve per given area.
If you are not supplementing with CO2 and are growing a fruiting/flowering crop, then stay around 900-1,000 micromoles.
If you are supplementing with CO2 and are growing a fruiting/flowering crop, then you can go up to 1,200-1,400 micromoles.
Note: Adjust your room air temperature higher under LED lighting, about 85 degrees fahrenheit and 90 degrees under high light/CO2 conditions.
EXAMPLE: Your area is 4ft by 4ft and you want 1,000 micromoles PPFD, 4ft x 4ft = 16 square feet.
175W PCBs: 16 square feet x 0.238 PCBs per square foot = 3.808 PCBs, round to nearest whole number = 4 175w PCBs needed to get 1,000 micromoles PPFD average in 4 x 4ft (16sq ft) area.
90W PCBs: 16 square feet x 0.476 PCBs per square foot = 7.616 PCBs, round to nearest whole number = 8 90w PCBs needed to get 1,000 micromoles PPFD average in 4 x 4ft (16sq ft) area.
175W LED PCB (At 1050mA drive current) – System Level
Factored total losses of 18.5% (about 2.2um/j @ wall, to be conservative)

Looking at getting into DIY LED and was considering getting a few of these gen 2 boards. Has anyone gotten a chance to try these out in the real world yet? Curious about the footprint. I have a 4x4 space and the info on the site suggests 8 boards to cover that space. Seems excessive to me but I understand they are being conservative. Any real world recommendations about the coverage you get from a single board?

Six 90w boards would work fine and good even coverage I use 3 90w boards in a 2x4 and they are killing like HPS

I noticed the boards went up in price a lot. so I'm going to use wavy boards instead. layout as a Plus sin using 4,:with nothing in the center, and 4 veros in the corners all @75w for a 600w build.

well, again, thats not a metric. not any more than your conclusion that "cobs perform better at 700 mA than 1400 mA" based on uncontrolled anecdotal tests
i did finally get my chips and will be testing.
It is a completely different animal though, its not really apples to apples. Vitale's PAR numbers are somewhat inflated relative to other designs for a few reasons:
-spectrum uses blue monos and has more blue spectrum than QBs or COBs
-Vitale's PAR tests integrate 350-750 nm as opposed to the usual 400-700 industry standard. Im not saying plants dont absorb energy in those wavelengths but taking 380 nm energy and weighting its PAR energy equally with higher wavelengths will bias PAR readings higher than other people's tests. While UV *might* be useful for terp development its probably not equivalent to say that umols measured at 380 are as useful to the plant as even 500-600 nm wavelengths provided in abundance by white phosphor LEDs
i expect the white channels to test similar to QBs and cobs. based on # of chips, for the price i think COBs will have an advantage in efficiency/$. on a white-only basis the (more expensive) 90W chilled LED has less diodes than a QB and they are spaced a lot closer together. this combined with the small footprint of the chilleds i expect the samsungs on these boards to not do as well as on the QBs. the 175W board is the same small footprint and has the diodes even closer together so that will dent its efficiency a bit.
They are a great design and the spectrum looks solid. its very premature to say whether one design is heads above another, we simply dont have that data, and with spectras being tweaked, umol/J isnt the be all end all, otherwise wed all be growing with blue monos or 6500k cobs

Fucking cuck bud beefy dam what strange is under it I'm having a hard time right now with seeds the state I live in is selling cards for medical and if you have medical assistance or one pain management they give it to you to automatically your medical cannabis card but 2018 can't use them until what you f****** ridiculous but inside of my state and estate inside of a state which is b******* District of Columbia it's already legal medical purposes
