Cheap build help! QB vero29 EB strips Samsung M strips

PicklesRus · Apr 4, 2017

Any opinions on the best place to start for a 1000w replacement build on a budget?

Which is the cheapest option?

Quantum Boards
Samsung M strips
Samsung F strips
Bridgelux EB strips
Bridgelux Vero29

Running the q uantums at big wattage would be my choice at 1400ma....100+ watts and near 50% eff even with losses.....Vero 29c would be my 2nd choice because of nearly the same...yet with a bunch of voltage you would need to solder each vero to be safe imho...so even samsung strips might be a better 2nd place...

Bigger meanwells at least, are cheaper per watt as well...

How do quantum's rate better than M strips?

I linked yesterday to arrow who do 25x 4ft M strips for $390

I thought his question was he had to replace a 1000w on a budget and what was the cheapest to build, not what is cheapest to run. Nevermind that realistically you are recommending an unavailable product. There are people who have waited months and still only *might* be able to order some for early may. Miss that batch and they have 6 week lead time for more diodes which will sellout in a day. You'd be better off recommending him buying lm561c strips made by samsung themselves. They dont exist yet but likely will before you'd get a quantum board.

i stand by my statement it wasnt made willy nilly if that is what you are suggesting...

1qb ran at 1400 ma is 160 watts at 50% and to replace with strips would require 80 par watts.

Semantics is another discussion.......i didnt walk into this yesterday but thanks for looking out.

I think we are going with 6 eb strips at 1.4A - depending how that goes we will cover the whole 4x12 with ebs

Think about strips the more I think that cobs are really going to die out here - i know cobs obviously work but it just doesn't seem to make sense if there are strips on the market

You missed the point entirely. That wasnt the OPs question. His question was what was the cheapest to build a light that i can use to replace a 1000w in a garden.

I wasnt suggesting you said it willy nilly, i was suggesting you were answering a question different than what he asked.

He ended up answering it himself, the cheapest option is the eb strips. It wont be the best light, or the most efficient light, or produce the best crop of them, but it will cost him the least to get it running.

What do you mean it won't produce the best crop? What would make a better crop?

@haze010
They exist and they are available! Samsung H-Series, gen.3 use 561c ... But they cost twice as much as the EB-Series...

@PicklesRus
If you want it cheap, take the EB strips. If you want maximum efficiency, take the H-strip from Samsung. They are considerably cheaper if you buy more than 25 and they are at least as efficient as the QB/S5 bin!
Unfortunately, Samsung does not say which binnings they use in the H-Series Strips, but 179lm / w @ 80mA suggests it's S6

PicklesRus · Apr 8, 2017

I know there are LEDs that are more efficient, but why would more efficient = better crop?

You will get what you invest! Do not note such a stupid statements, only made to provoke ...
You can build great and efficient lights with only EB series strips, fact!

More efficient means more light from the same amount of power. 1000w H-Series produce more usable light as 1000w EB-Series. No better crop but more weight..
And the higher upfront costs are quickly restored with the extra income!
Or if you go the PPFD route, you need only 8-9 H-Series Strips to get the same footprint as 10 EB Strips.

I understand. I was just wondering if there was something I didn't know.

I think he just wanted to make you unsure.

Meh. That's OK. I am wondering though what I'm missing from the spectrum. It's 3000 and 4000K. I was thinking to add some Red monos. And a flower initiator something like that @Growmau5 or @brahbbyB have made. Awesome work from everyone.

What do you want to build, just an overhead light or some kind of suncloak copy?

Suncloak look just like what we want to do.

Randomblame · Apr 8, 2017

I like the idea of surrounding lights very much and plan a similar build but very much smaller (1.2 * 0.8m) using 30pcs. of 560mm H-Series(6S5P/70mA each 561c/420mA each strip) and a HLG-320H-2100B for a 300w cloak.

you left out chilledledgrowlights. They also use samsung chips and also color correction and produce commercial grow lights or DIY kits too. They have reports of comparison to HPS etc. They have a 600w light nthat replaces a 1000w HPS. check them out. he is taking pre-orders now and delivering in May/June QB competition. If building your own lights, I would consider cree cxb running at 50W/SF as my second option after ChilledLed Gen2 boards.
