Just an update girls are thriving and taking off super healthy , running 12 x 4ft eb strips gen1 on a hlg320a-1050 driver at max drive 10-12” from canopy tops recently flipped lights so we will see it budding shortly , hopefully my gen2 will b in the mail soon aswell to do a comparison

What kind of light did you used before? Do you experience more side branching?

I received some 3500k strips yesterday and am waiting on some 5000k's to finish the build.Has anyone who ordered the EB gen2's received a shipping notice on the 5000k strips?

Did they just raise the prices like 20-25% on Gen 2 on dk or am I crazy?

Was ordering everything for build, last thing I need is the strips, and now they look expensive. Damnnn.

They have become cheaper. I bought my first strips (gen1) 1 year ago and payed a few cents more. 2 months ago I bought some strips (gen1) again, and I had to get 1 more strip, to get over 50€. Now I bought some gen2, and they are even cheaper again. If you want to know the correct amount, I can check my digikey account. But as I said, I guess it’s less than 0,10€ overall for the 1ft strips.

When I pre-ordered my gen2 strips 2 months ago, I also had to pay more. They didn‘t delivered in time, and my money went into a credit, which I was able to use now, when I ordered again 2 days ago. Now I am getting 1 (41 instead of 40) more strips for the same amount I had to pay 2 months ago.

How do I get the wires out off the Wago port on the Gen 2s. I wanted to check that they work with my driver, but I'm stuck trying to pull a wire out. I see the small hole near where you insert the wire. I've tried pulling the wire as i pressed a small screw driver in it. Nevermind I was babying them to much, I got it out.

Hello, I'd like to make a DIY microgrow cab.


BXEB-L0280Z-35E1000-C-B3


And here five questions, hoping in a your answer.

1)i do not understand if i must use an heatsink like i did with my COBs or if it just depend from courrent amount i will adopt (in that project not more than 35W)
On bridgelux datasheet they say "No separate heat sinking required",but samsung say yes....

2)I'd like to run four or five(dimmable) strips, would it be the same wiring in series VS parallel?
in the second case what about MW HLG-60H-24A, seems right but i can't find one more efficient.

3)do you know, if any, the differences between MeanWell Taiwan and MeanWell USA?

4)which are the differences between samsung like that SI-B8U05128HUS and bridgelux? bridgelux stripes mount samsung smd, am I wrong?

5)does 3500K case lots of streach (space wpuld be tiny)or could it be fine as "all in one" cab? Or should be better to use 3000K for bloom and 5000 or 6500k for veg?

Sorry for my bad english and if my post could seem unpolite.

REGARDS AND HAPPY 2018!!

Below nominal current (350ma) you don‘t need a hestsink, if you go upwards (700ma), it could be useful to get some heatsinks (alu c-channel, or a thin alu sheet).

2)I'd like to run four or five(dimmable) strips, would it be the same wiring in series VS parallel?
in the second case what about MW HLG-60H-24A, seems right but i can't find one more efficient.

If you don‘t need more than 35w, the driver would be over rated. HLG-40H-20A is already more than enough for your project. And no, series and parallel wiring would be different, with this drivers you should go parallel. That‘s more work to wire, but it‘s more safe (20V instead of 120V). You can do a combination of series and parallel wiring, and use a more efficient driver: HLG-40H-42A (0,5% more efficient)

3)do you know, if any, the differences between MeanWell Taiwan and MeanWell USA?

I don‘t know.

4)which are the differences between samsung like that SI-B8U05128HUS and bridgelux? bridgelux stripes mount samsung smd, am I wrong?

Samsung uses more efficient diods than Bridgelux. Bridgelux is using their own diods. Samsung 180-200lm/w, Bridgelux (gen2) 170-190lm/w

5)does 3500K case lots of streach (space wpuld be tiny)or could it be fine as "all in one" cab? Or should be better to use 3000K for bloom and 5000 or 6500k for veg?

Gen2 just came out (https://www.digikey.at/product-detail/de/bridgelux/BXEB-L0280Z-35E1000-C-B3/976-1736-ND/7907665) but only as 3500K and 5000K. I am height restricted and I prefer to mix them 1:1, or 2:1.

Sorry for my bad english and if my post could seem unpolite.

REGARDS AND HAPPY 2018!!

Yeah happy constructing! And if you prefer the old strips, for example because of the spectrum, just change the voltage I suggested. Gen1 = 24v / 48v, Gen2 = 20v / 42v

Got my gen 2 light built and hung today.

10x 560mm 3500k strips wired in series, driven by a HLG-240H-C1050A meanwell. 10 strips is only about 200 forward volts, leaving me with about 40 to play with. (the driver maxes out at just under 240v.)

The Driver gets a lot warmer than I expected. Is there any way I can use those leftover forward volts on cooling fans? Are there fans that I can wire in series to use up the last 40v at 1050mA?

Most DC cooling fans I see only take about 300mA... so I imagine that running these in series will just burn them out. Are there higher current (1000mA-ish) DC fans out there?

Thanks

The price break for multiples is quite good on digikey.
I got 10 strips and basically paid for 9 if you use the singles price.

1. No heatsink required when driven with 350mA(1ft.EB-strip), if you drive them higher(525 or 700mA) you need at least an alu-sheet.

2. With a HLG-60H-20A you need to wire all the strips in parallel, with a HLG-60H-C350 you need to wire them in series.

3. Nope! Meanwell is Meanwell

4. Samsung use SMD5630 footprint while Bridgelux use SMD2835. Samsung use their own LM561c and Bridgelux use their own Bridgelux SMD 2835 0.2W 3V diodes.

5. Nope, no stretch with only 3500°k! But for a tiny space I would use 4000°k only or a mix of 5000°k and 3000°k. 4000°k is also a good all-in-one solution and delivers great results. Remember CMH bulbs have a 4250°k spectrum with deliver very good results.

Damn the 5000k gen2s just moved to March as an estimated shipping date!

EDIT: Just had them on the phone. 5000k arrived today and are shipping out!

Randomblame and Serva, thankyou so much for your kind answer.

So why do not adopt samsung instead of bridgelux habing a better efficiency?

I alreadh knew that with HLG-60H-20A I'd have to wire all the strips in parallel just asked you if there is any more efficient and if there are not any problems on parallel stripping like with COB without put resistor between COB...wire in parallel would be really nice and safier because the low voltage..any pro/cons?

So do you suggest me to use 4000k or 3000+5000K but Serva 3500K+5000k 1:1 or 2:1 ratio....


I'm a little bit confused expeciallybif gen2 come only in 3500k and 5000k and gen1 would be less efficient..

Maybe on the future i'l keep my citi 1212 3500K (really happybwith those)into my growtent and BXEB to keep moherplant...is 3500k so different from my 1212 3500k 90cri?


Thanx again, i really love this forum, really generous and educative!!

@rocho I believe the spectrum chosen is based off of personal preference. The mix of spectrum lights allows flexibility when you're able to dim multiple drivers to achieve desired results. I believe having seedlings and clones under the 5000k while there rooting or vegging and being able to add the 3500k when you getting ready to flower is an convenient option.
