possible v loss from thin wires or too long of wire runs ? i had to rewire mine with 14g power runs and 16g to the strips with as short runs as possible, less voltage drop...i have the B drivers also and cant adjust voltage either just current, so you'll need to get as much v as possible

I am going to rewire everything tomorrow. It has something to do with the wiring since last run I had apparently no problems even if I never tested it: I harvested 200gr off it, I doubt that was 70-80watt.

i looked again and it is 19.5v but .7a. so 16x.7x19.5=218watts

BXEB-L0560Z-35E2000-C-B3

If we look at the datasheet, page 6 figure 3 we can see that at 400mA voltage is 19v
Since I have 450mA per strip, voltage should be a bit over 19v.

I got the wrong driver probably

i did the same. got the wrong driver......plenty of power, but cant adjust the voltage...we need to get the volts up just a little bit more then we can full crank out..... .....i cant max my 480`B driver out...got to get the 480A now....

good luck

OK I rewired my fixture, got about 50watts on a HLG-150h-42B

Today I desoldered the potentiometer and watt-a-meter shows 163watts.

Last run I harvasted 200g from less than 100watts. How da fuck?

So this will be my first full run under Led
What is the parameters for seedlings I've been running 23w/ft at 20in I feel like they might have too much light is this possible

Hi from Spain!
I'm thinking about build a lamp formed by 16 BXEB-L1120Z-40E4000 in a 5x5 grow tent.
I do not know what driver to use for this system, it's new for me. This leds needs heat sink?
Someone could help me?

If you run them at .7amps you need no heat sink. I use 18 strips in a 4x4.
16stripsx.7ax39v=439wats
16stripsx1.4ax39v=873wats
Now you have to deside how hard you want to run them, they are less efficient the harder you run plus you need heat sinks.
Hlg 600 would do the trick.

Thx Turpman!!
I think that, this HLG-600H-42A is OK for my light set. Its correct?
What type of heat sinks need for this strips?

Maybe someone here can answer this for me. I’m running 12 strips 1 foot. On hlg 240. How hard can I run these with this driver? Currently running at about 550ma per strips. Wired in parallel.

Depends if have cooling. I use a lazer temp gauge to double check.

hi guys.
I'm going to buy at HLG-60H-C350B to drive 6 (in the future 10?)bridgelux EB series (not the latest generation)560mm at 350mA (without heatsink)
Can you explain me why there are two difefrent version under the same producrt code ? one is the classic CC and the other one CC + CV(check on mouser and you'll see unfortunately only the second one)

Do i take any advantage choosing a CC + Cv driver instead of a CC, wiring the stripes in series?

I do not have idea how it works and how to set up but i could learn ..maybe ..;)

I do not need more Watt, but just in case of that what kind of(cheap/on a budget project) heatsink may i adopt as passive cooling to push them up to 700 mA, in that case please sugest me a link.
sorry for my shitty english, one love!

Hi again, I have another last question.

Do you think can I manage 10 (mixed)EB strips whit a 200v cc driver?

I already have six EBseries stripes, first generation.
22.1V at 700mA but i can not find any calculator, according to data sheet should be 21.7V run at 500 mA and 21.0V at 200mA.(I can not find how much Volts at 350mA)50°C

I' d like to add 4 EB second gen.
They drain less voltage, 19.5 drive at 700mA.(again I can not find how much at 350mA).25°C

Unfortunately i do not find any calculator like cree, citizen and samsung have.


I THINK that 6 gen1+4 gen2 bridgelux should be not more than 206-208V.

Hlg60h 350B drop 200V max, but I remember that some MW driver in the B version without potentiometer wire could give some extra volts(open circuit) i can not find this information on this driver datasheet.


Sorry for my shitty english and for wrong technical terms i eventualy adopted.
Regards

Anyone ever wire 2 in series?
I got two HLG-185h-36a off ebay for $30 and Iv got a bunch of 1’ strips laying around.

With heat sinks I think you can run them to 1.4a or more. Again check your temps though.

Hydro food yes you can run as many as you like in series. I have a couple small areas I run 4 in series. Higher volts means less line loss better efficiency but more danger on electrocution. If you wire and insulate properly no issues there though.

Running at 1.4 would double the max of 700ma.
