presently getting 1130mm5621c s6 x 2mm aluminum x 22mm 54 v strips custom made for WHOLESALE by the 100
i think strips are the way to go "also"
Cheap build help! QB vero29 EB strips Samsung M strips

Wow just thinking in my head about a cloaked 1.2x0.8 using these strips makes me happy
iShit yeah nice one! That's what its all about right. How many lm561c per strip? How much is that setting you back? Probably cheaper AND ALU!

i think 144...1170mm .[too much going on today]i can sell them around 15 usd in 100 lots
yes plus they are on serious 2mm aluminum
also making 32 "..so with both i can make a Suncloak style light

Pretty much this, if you put 1000w into an eb strip build and 1000w into a lm561c samsung build, the samsung will have a better crop.
To me "a better crop" in this case i meant same quality bud just more of it (more efficient light means more light to the plants at same power draw).
We were basically saying the same thing.

Ah, that makes sense. I was thinking the other way.
I'm comparing output, not watts. I know already samsung is more efficient.

Here's comparing EB Strips and Samsung H strips.
Things you can learn from this:
Things you can learn from this:
- If you need absolute cheapest startup cost, EBs win but will operate at 134lm/w
- If you plan on running EBs soft at 700ma (156lm/w) $350,
you might be better to get Samsung H's and run them at max power 2.1A (163lm/w) $370 - Running Samsung H strips soft is f'ing expensive

If you want efficiency and Wattage, cobs are still cheaper 16x Vero29 C and run them at 700mA. 57% efficient. Active cooling on them with heatsink USA, should be around 480 for the cobs +400 for drivers(higher estimation) +200 for heatsink/fans other driver. = $1080 pushing 800W perfect for replacing a 1000W hps

The intent of these isn't for people who have $1000+ budget to build a light. For people with small spaces and small budgets for a personal grow closet its hard to beat. For the street cost of an ounce you can have light more than capable of flowering a 2.5x2.5 where there is minimal heat output and the light can be a foot away from the plant.
hey. do you have any link for that strips, what i need more, aprox. budget, it would really help me . i would like to buy them for my 1,8m x 1m x 2m grow room. but dont know how many

Bridgelux EB series, 156lm/w @700mA(165lm/w @350mA)
https://www.digikey.de/products/de?keywords=Bridgelux BXEB-L0560Z-30E2000-C-A3
Samsung H series, 179lm/w @480mA(same diodes as Quantumboards, probably other binnings)
https://www.digikey.de/products/en?FV=ffecd480
Samsung F series, 168lm/w @1120mA(same diodes as H-Series but driven higher)
https://www.digikey.de/product-detail/de/samsung-semiconductor-inc/SI-B8V261560WW/1510-2217-ND/6624001
These are only 2'ft. strips, 560mm. They are also available in 1'ft, 280mm and 4'ft. 1120mm and the F series also as double row strips. You can search on digikey's website by brand and series to find all strips of a series(Samsung H and F series, Bridgelux EB sereis).
BTW,
Longer strips are cheaper than shorter strips and double row is cheaper as single row. 700-800w should be enough for your 1,8m²/19,3sft. ~36-40w/sft. Take 3.000-3.500°k strips, they are good for both vegging and flowering.

The f series arent available yet, noone has had them for sale and if you hit check lead times it says they are already 6+ weeks overdue and for more info to contact digikey.
So you can scratch F series as an option unless you feel like waiting an undetermined amount of time till they are actually produced.

thx really appreciated!!! sry because i am such a noob this is my last question. how many o them ?

Choose how efficient the strips should run, then calculate how much electricity is consumed by one strip. Then divide the result by the desired total performance.
Example:
A 2'ft. EB series strip needs 22.1V @ 700mA and provides 2410lm (from datadsheet) at 15.5w. Suppose we want 700w total
15.5w) you need 45 strips, x 2410lm, making 108.450lm total. Distribute the strips evenly over the entire surface, eg. with a frame made of aluninum L-profiles or use two large 3-4mm thick aluminum sheets and screw the strips there.
You need the datasheets to each strips(download them from digikey) to calculate output, voltage and currents of the whole build!
