Need the forums opinion on this Bridgelux 100w chip

[speyfly]

I'm in the process of designing a 600w LED array to go with another 600w that I currently have and wanted to get your feedback on the chips, power supplies heat sinks, fans and the rest of the peripherals that go along with the core items. This light will be used for flowering only.

This chip is built by Generic 100w and the par values look pretty good, whats your thoughts?

No good friend. Look into vero29 / cree cxa3070 cxb3070 or cxb3590

Hi Stephen, now that you have my attention and I'm a long time toker (40+ years) that appreciates quality of product but growing is very new to me.

With that being said, in your opinion what would be the perfect chip selection for a light that will be 4' X 2' to grow a stellar crop of 4 plants?

I really appreciate any insight you and other on the forum might be willing to share...

My garden is about 2x4. I use 4 cxb 3590, 3500k @ 48w each along with 4 Vero29 4k @ 80 w each. They are spread out on a frame that is 12 x 48. WORKS GREAT.

Your choices of gear will depend on your GROW style and plant height and most importantly your budget.

4 plants in that space will be crowded and requires good training to make the most of the lighting.

 

[Stephenj37826]

Yes depends on budget. Id go with cxb3590 3500k CD bin if I could 4 of those on the new meanwell hlg240hc1750 would be a good start in that space. Look up kingbrite on alibaba. Jerry is who you are looking for. He has the LEDs drivers holders and lenses. It depends on your ceiling height really. If it's under 6 feet go bare cob. Also look at thread about heatsinks. A nice passive heatsink USA is what you want.

 

[speyfly]

OK, I like what I've heard and read so far, now to the meat of it question. The light footprint that I want to cover is 3' X 5". What chip sets would I want to get the best yield. I would like to try to keep the cost down, say $500.

 

[Stephenj37826]

Vero29 or cxa3070 on hlg185h 36 . 4 per driver 3 drivers 12 cobs. For 500 you could start with 8 and 2 drivers. Work your way up from there. 2 will work fine in your area as long as you do proper training pruning.

 

[speyfly]

Stephen, I have to say thank you for the help with this build. I will go with your recommendation and use the Cree CXA3070 80CRI 3000K (I think that is the right chip), will this chip give me what I need for both veg and bloom or do I need to think about other chips to cover the necessary light spectrum to grow a healthy crop.

Also, do you have a recommendation to source parts like the chips, power supplies, lenses or reflectors, heat sinks, cooling fans and the like?

Once again, many thx...

Look up kingbrite on alibaba. You need Jerry ming. Tell him I sent you. He will get you fixed up with LEDs holders lenses. I'd go with heatsink USA on heatsinks. Look up heatsinks for diy thread on here to help you figure heatsink size. Post your choice before purchasing and tag me I'll check your math.

I checked out both Alibaba and HeatSinksUSA and both placed looks like they will have what I need.

If I were to build the light using the 12" X 36" heat sink as the platform what kind of light footprint should I expect using 8 CXA3050's w/90 deg reflector cups or lenses. Also, what kind of a diode arrangement would you suggest (symmetrical, offset, other) for the best coverage?

I'll be getting in touch with your contact Mr. Ming in the next couple of days and have you take a look at the numbers. Stephen, you've been so much help my friend, hope to return the favor or at the very least, pay it forward...

I would stick with cxa3070 Jerry's prices will surprise you. Also heatsink USA has discount code giveme10 I believe to save 10%.

What is your ceiling height? If it is under 5 feet I would probably use holders and no lenses or reflectors. Just curious if it is a tent or cabinet? As long as you have reflective material all the way you'll be good bare cob. For that space a perfect combo to me would be 6-8 cxa3070 on hlg320h-36a. That's the perfect amount of light in there. Also check with Jerry on that driver as well. 8 cxa3070 @ 22.50 + 100 for driver and 1 heatsink USA 12" x36" with shipping and discount should be 180 total . Holders are 2.50 a piece. So this setup should get you in there for 500 or so and be kick ass for your space. You'll be running @ 1.125 so pretty soft as well. You should be around 45% efficient and passive cooled. Nice. You may go over budget 20 bucks possibly after shipping from Jerry but that will be an awesome setup.

Of course you'll need screws wire and thermal paste. So actually you might be at 540. I'd save up the extra 40 and go this way. As far as cob spacing I'd get 2 dead center at the ends stager the other six 3 on each side of hs.

Hey Stephen, the ceiling in the grow room is 7' usable. Also would I gain any benefits if I increased the length of the heat sink from 36" to 40" or even 48"?

Regarding the dead center diode placement, would the midship diodes be all the way to the end of the heat sink centered or center the light between the 2 end outboard lights and the 2 outboard center lights? Hope this question makes sense...

I'll draw you up a picture when I get home later on.

With 7' you could use reflectors . you will need adapters as well. If go ahead and buy the adapters and install them but put the light up and see what you think before going with reflectors. Easily added later on.

Hey Stephen, I was able to talk with Jerry and thank you for the heads up on this supplier. I will be placing the order today but i do have 2 questions if I may ask. On the power supply that you recommended, from the research I did it looks like I will need 2 of the power supplies to run 8 of the CXA3070's, is this correct? Heat sink fans, 1 or 2? And Jerry has the power supplies and at a great price!

The power supply I gave you hlg320h-36a would be ideal for all 8 running in parallel. That would be a perfect fit your space. It would run them @ 1.125amps roughly. So only 1 of those.

 

[speyfly]

All good stuff Stephen, you're one of the good guys. Parts are on their way, this will be a fun and an educational build and a primer for future projects.

 

[speyfly]

Hi Stephen, while I'm waiting for the parts I been trying to come up with the cob spacing on the hs, this is what I've come up with but it pretty symmetrical.



You had mentioned an staggered offset spacing, Can you elaborate a little on that spacing and benefits.

Thx

I think the pic with 1 cob at each end will be the best honestly. You have the right idea there. You could maybe offset each of the two outer rows where the cobs would not be in line with each other if you get my drift.
