1920w and 1280w monster strip builds

[whytewidow]

How many watts per sq/ft to get that much lux?

That was in an open room no reflective sides. I didnt build it for a certain area. Jus wanted to check out these strips bc I got a ton of them. But I only checked a 2x2 square. So 4sqft, at roughly 35w sqft The four 40 diode lm301b strips are being pushed at 24.5v @680mA each. Max is 1.2A 16.66w per strip. Total 66.64w for those. The Cree cobs are being pushed at 37.6v @900mA 1800mA max. 33.84w each for a total of 67.68w and the four bridgelux are at 21.6v @450mA 1400mA max. 9.72w each for a total 38.88w

So total the whole light is pushing 139.6w give or take. But I'm also not sure how accurate the lux reader is. Randomblame is the one who told me about it. He said it's close if I remember right. I used the same one with my H inFlux_L06 build, my 16 strip bridgelux build, and the 660w F series Gen 3 build.

Coming together. My work bench table in the garage is too small for these. So I gotta cut all my stuff out there. And put it together on the living room floor.

What drivers for this one? With so many strips, I'm curious to see the wiring.

What drivers for this one? With so many strips, I'm curious to see the wiring.

HLG-480-48A in parallel. Multiple drivers. They will be run low. Somewhere in the neighborhood of 480mA-525mA these strips dont even need heatsinks below 750mA. But for rigidity I'm using them. And if he ever decides to go bigger. They are run so low below max, he can add another driver later on down the road. And push up to 2880w and still be safe. 64-66 strips total spread over 5x10 area.

The other light will be probably 40ish strips spread over a 4x8 area. But its flower only.

what's the difference between running in parallel, and running in sync, or what ever it is?

 

[whytewidow]

Must be a difference in our meters.. I'm getting around 60k lux at 50 watts a foot with 253x lm561c diodes per foot

They're not lm561c. They are 4 strips of lm301b and 4 strips of bridgelux. Plus 2 cobs. And depending what strips you have having 253 diodes what strips have an odd number? To make 253 diodes? Or do you have different strips to make the odd diode? I have more than that jus in the bridgelux. I have 448 Bridgelux diodes without anything else. Plus 4 more strips and 2 cobs. Not sure what you're meaning. Lol. And like I said I'm not sure exactly how accurate it is. But if you're getting what your getting with 253. Then what I'm getting is low. I have 3 times the diodes. And cobs.

 

[whytewidow]

I see you mean 253 diode per ft. I thought you meant 253 diodes.

Sync isnt a type of wiring. Phone must've autocorrected. I think you meant series. But anyway you have parallel, series, and series parallel. Series you make a loop with one wire out + to + on strip then out the other end of the strip from - to + to the next strip. Then - out on the other end to + of the next strip. Then - back to the driver.

Parallel is both +- to each strip. Or both +- from end of a strip to the next. And not back to the driver.

Series parallel is strips wired in series then back to the driver in parallel. So like 3 groups of 3 strips 9 total. In series. Then both + and - from driver to each end of the groups.

In series you add up the voltage of each strip.
And the current is the same across all strips.

In Parallel the voltage is the same. And say 10amp driver. It would push 2A to each strip. Just an example.

cool thanks for that! and yeah that's what I meant, just couldn't remember the name of it, lmfao!

so what's the best? and why do ppl argue over which is better?

 

[tman42]

Looking good, can't wait to see one of these lights lit up!

 

[whytewidow]

Yeah I was just telling you how many diodes per square foot and the wattage per square foot just so you have an idea as to the efficiency.. My meter must be way the fuck off..

Oh gotcha. Honestly it might not be yours. Might be the shitter I got. But i can say it read 109,000 lux on a 120k lux bulb. So it must be sortve in the ballpark. But there is 2 little apps for android. Called lux light meter, and physics toolbox light. .they read within 500-750 the meter I have. But I'm not sure the sensor on the phones can actually read lux. But it's close to the 45 dollar meter a buddy gave me. Also may not be accurate. I'm sure to be accurate a decent meter needs calibrated and whatnot. And mine doesnt. The only thing it does have, is master reset. But I havent pressed it. Bc it hasnt been actin up or anything. And I'm not even 100% sure the diodes on the 40 diode strip are even lm301b. They are an Alibaba venture.

Finally got all the freakin parts for these lights. Time to get em together. And get em burning.

WooHoo!!!

WooHoo!!!

Dude it's been unreal with the parts for this light. Between the hold.up with the strips, and then tnutz sending the wrong parts. It's like the grow gods wanna stress me out some before hand.

Man I totally understand and am not stressing on anything. Just can't wait to get both of the lights into action soon!

I'll post some pics of it together tonight. Almost done with mounting the strips. To the tnutz bars. Dude this thing weighs less than the driver. It's super light.

 

[whytewidow]

Just this section is 480w. 16 strips run at 625mA each. Theres 4 of these that will connect together for 1920w once hung. Or two separate fixtures of 960w. Or four 480w fixtures. But will most likely be hung as two 920w fixtures. Super light weight, minus the driver.

dude TV Reception will be awesome

I'm hoping to get all the premium channels.

Hows the build going ?

im waiting to see the next batch of pics, see how you wire everything and clean it all up

Cant thank you enough for all the help man

Pretty good got 1 1/2 sections to finish up mounting. Then gonna wire it all up, heatshrink all the connections put the t slot cap in to hide everything. Light her up and snag a par map.

No problem man. Anytime.
