Bridgelux EB-series on a 2' x 4' SCROG

Im using 8 of the 560mm strips and a hlg185c-1050b. This is how mine are wired. Yours look to be in parallel. These things are pretty damn bright! Pulls 217w without the potentiometer hooked up.
God Damnit, that photo is exactly what I'm looking for. Thanx!!!

So, anyone know if there is a secret method for removing wires from these EB connectors? (I found it. Just push down in the groove on top of the connector. Wires *usually* pull right out.

Now that's what I'm talking about! That is a serious blanket of photons raining down now...and it comes at a good time. You can finish the run strong with plenty of photons.

And I would definitely suggest getting some UV grow glasses. I have a very similar setup, and my eyes hurt if I do not wear them everytime I am near those lights.


And if that is just your second grow...well...it reminds me of a Will Rodgers quote:
“There are three kinds of men. The ones that learn by readin’. The few who learn by observation. The rest of them have to pee on the electric fence for themselves.”
You must be one of the few!:mrgreen:

That's awesome. Now that's a well lit grow space! This is exactly what these forums are for.
Awesome, for sure! Now I need to tune up the height above the canopy.

The temp on the angle aluminum picked up 10'C to 35'C, so good that I chose the aluminum angle.

I'm gonna be curious how my girls like all these photons.

No kiddin'. Looking forward to having these babies cranked up through the 12/12 bloom.

Yup. Shades are on my shopping list.

Thanx, Bud. That means a lot. I gotta add, though, that having access to you all as a resource is invaluable. Had no one said anything about my lights looking subdued, I'd have blindly carried on at 30% of potential. Thanx to all!

What would you guys say is the minimum amount of space to leave between strips? Just wondering if you can lay these things side by side on a sheet or if strips and gaps for air flow is the better option.

Honestly, I can't believe you were getting ANY light from them hooked up that way. I'm baffled as to why you saw 191V on the driver output. By all logic it should have undervolted/overcurrented and shut down as soon as it was hooked up.

Glad you got them going right!

Yeah, can't explain the reasoning for the wiring. I asked on another forum how to wire these EBs up in serial and was given a link to a diagram of the pattern I had. I'd thought that for serial the wires should go (+) --> (-), but it was easier to believe the post. Naivete on my part since it was (now clearly) wrong info.

I left ~0.75 inches between my mounted strips. When I redo my lights at some point I expect I'll spread them out a bit more to push the direct light out to the edge of the scrog. I do like leaving some space between so that I can lay my fans on top of the light frame and blowing down. That way the fans cool the frame and also blows through to keep the plants moving and aerated.

I am going to pull the trigger on one of these builds.
I am thinking:
10 x BXEB-L0560Z-30E2000-C-A3
5 x BXEB-L0560Z-57E2000-C-A3
Digikey has stock so about $120 USD
each with a separate dimmable driver (to be outside the grow area)
1400ma @ 23.3vf 32.6watts (according to spec sheet) I dont care about the efficiency at 700ma
I will have active cooling over the panel. If I have to I will build a hood.
I am thinking of spacing these with 10mm gaps (little less than half an inch)
That would give me
(24mm*15 strips)+(10mm*16 gaps)=520mm (20.5 inches) plus frame wide
and 560mm+13mm+13mm = 586mm long (23 inches)
I was thinking 1/8"x1"x8' aluminum flats with half inch angle for outer frame.
That would be about $50 USD at home depot

Add some misc costs and you are about $200 USD (without driver costs, TBD)
Seems like a ridiculous amount of power off a roughly 60cm / 24" panel. I am thinking that this could be used in a 2x2 to 3'x3' tent.

So my questions are:
Driver selections ?
I would like both dimming B models (ext dimmer) one to handle 5 strips the other to handle 10, or maybe I have to fudge the qty of strips a bit? Keeping under 24" square is the goal.
Is 1/8" aluminum thick enough?
Is a half inch gap enough between strips?
What would I be looking at min to max wattage?

HLG-320H-C1400B for 10 3k strips in series, 233v x 1,4A = ~326,2w net., 347w total(10 are maybe to much, 9 would work for sure, test it out)
HLG-185H-C1400B for 5 5k strips in series, 116,5v x 1,4A = ~163,1w net., 173,5w total
Yes
Yes
and both setups are dimmable, so....Lol!

Thanx, Twist. I'm not sure where you're getting the 24v from. Can you elucidate? I'm using the BXEB-L1120Z by the way. From the spec sheet the Fv at 1a should be ~50v, since the driver maxs out at 190v output, 190v / 4 strips should give me ~50v/strip. What's wrong with my calcs?



Yeah, depending on the yield on this grow, I think I'll probably add another 4 strips for a total of 12.
My bad - I had a quick scan through and mistakenly thought u were using the 560mm strips.
