Hlg185H-48a

Gonna run 3 on this driver. Which is 75.3 watts each. Gonna run (1) 3000k and (2) 2700k for roughly 226 watts.

3 1818@ 75.3W each (226W max) or 4@ 55W ea (220W max), 5@ 43.4W ea (217W), or 6@ 35.9W ea (215W), etc.

Then I'm going to run the other (3) 3000k cobs on a HLG120H-48a driver.
(3) @50.7watts for a total of 152 watts

2 1818@ 78.5W each (157W max) or 3@ 50.7W ea (152W max), 4@ 37.4W ea (150W max), etc.

For total between the 6 cobs of roughly 378 watts.
Or run the two 2700k cobs on the hlg120 @78.5w for 157 total on the 2700k cobs. And then run the (4) 3000k cobs on the hlg185 driver at 55w for total of 220. For a total of 377 watts.

What do you guys think?

I haven't looked at all your drivers but isn't the HLG120h maxed out at 120w?
While I'm saying that, the HLG185 is maxed at 200w too.

I would like to point out though that I'm only really used to looking at CC drivers so I might be wrong.

Those are what they have listed. I didn't come up with those numbers myself. So I assumed they were right

Those numbers that I posted are from his website. But meanwell does say the 185 is maxed out at 200 watts. And it' listed on his website 4 1818s at 55w each for 220w total

Yeah I had a look just now. I would trust cobby over me any day and I'm me !:oops:

Take the lumens of high output how is 130-150,000 lumens. I think the strips put out like 24xx lumens so it would take quite a few

Lets say we just use them at Typical voltage and current.
For the FB24Bs I'm using if I were to drive my ten of them at 100W each to match your 1000W HID, they will be putting down about 170 000lumen.

Isn't driving them that hard defeating the purpose of being efficient? Idk what the max on those is?

Can you post a pic of them on here?

FB24 gen 3s are 4345-9300 lumen max according to digikey I believe. So you would need 13.9 of them driven to the max to make 130,000 lumens. So how are yours alot more. Bc that's awesome.

You are talking about LT-FB22B. FB24B has twice as many diodes.
theoretically, with enough heatsinking to keep them at 80C, the 10 strips could put out 262 030 lumens when driven to near max current at 3.6A

At that 3.6A setting, they will run at 152.3 lumens per Watt and with a 93% efficient driver that is an overall system performance of 141.7 lumens per Watt.

At Typical setting it is 168.7 l/W @ 93% = 156.5 lumens/Wat overall system performance.

And that's ten of them? Flowering a 2x2? Right??

Wheres the best place to get these? Arrow or digikey, mouse. Ect ect.

I have 10 of them but I would never use it on such a small space. You need about 100W on every 1x4. You get
4 types of these strips, 1.12meter and 0.56 meter in each of those you get units with one strip or 2 strips of LEDs....
It works out about $5 more per 100W strip to replace them with two half power strips, but you gain in better light coverage.
