Hey Supra, I know you probably get umpteen led questions a day but I've got one I cannot seem to find an answer to. Can you tell me what the efficiency of a Vero 29 4000k COB running @ 1050 milliamps is? I am going to run 5 of them on a Meanwell HLG-185H-C1050 driver, and I am trying to figure out whether or not I can passively cool them. Thanks in advance.

hey. i just wanted to thank you for the work you've put into the diy. tbh i've joined this forum just to read your post and just say thanks.

Hey Supra

I saw a chart awhile back that you made for a guy that said how many of 3070 could be put on various drivers. How many CXB3590's can be powered from the HGL-185H-C1400? I thought it was decently strong driver but I am half retarded and thats the good half lol. I have 9sq' I wanted 4-5 CXB's. Any options that may be better for me? Thanks in advance.

I'm trying to find a xml2 diy veg light with 30 xml2 I have utfse and can not find one any help would be awesome!

Hey Sup's how can you navigate through all the Leds at Home Depot? I'm interested in the T8 LEDs for a 2x4x7'area for veg. They state the spectrums and wattage and there was one in the 3600k range at 44 watts. Is there a formula that you can do to figure out if the the light is sufficient or not for the area mentioned above? I'm currently using a 6 bulb T5 and looking to cut cost. Thank you

Hello Supra. I was thinking about turning a small cab into a micro grow with leds. I would have 2 chambers split between 55"h x 9"d x 21"w. I think i'd have about 1.3 sq ft per chamber depending on how i divide the chambers, not 100% on that though. So following 50w/sqft what would be the ideal lighting for each chamber? 10x10w @ 50% efficacy? Some 20s? A 50 or 100? All run at 50% to get close to 50w/sqft.

And thanks so much for all the data you have posted already! As many others before me have said, I couldn't have figured this out so easily without your help!

Hi Supra! I have layouts for 2 rooms I'd love your opinion on. I used the calculator made from your data to come up with the numbers mostly. I'll use the 32v 3590 3500kv CD cobs. The smaller room will only be 4 feet tall so girls will be short & screened densely. PDF's are avail here: http://www.psg420.com/data/3x7.pdf & http://www.psg420.com/data/4x8.pdf. Hopefully this is an acceptable way to reach you :)

Hi Supra, I saw you mentioned needing the SPD of the 4000k CXB3590, and i believe that cutter does indeed have the info posted at this link: http://www.cutter.com.au/proddetail.php?prod=cut2811
And one question, what is the par/w or efficiency difference between a 4000k and 3500k CXB 3590 (both top bin) driven at 1050 mA?

I'm kicking around the idea of using 2x2 aluminum tube cut 36" then wield both ends off. Then drill a 1/2 inch hole in both ends and thread attach a 1/2 inch line and water cool 4 chips. Has anyone to your knowledge done this or is it not going to work lol.

Thanks brotha was sweating it.

I am relatively new to diy but a friend had a mw se-350-36 that I'm running 4 vero 29 parallel with fuses. Will this driver be OK to power this string? Not in full time use yet. Any recommendations would be appreciated.

Thank you so much for all of the info you provide for us all over the forums man. It is much appreciated. You saved me from buying another low quality light. Nothing but DIY from here on out. Thanks again man, take care.

Hey Supra, I copied your receipt of 4 Vero 29's, 3500K, using the Meanwell hlg-185h-c1400b in a module times 4. All modules are running on 700ma and 143 dcv. What can I do to get full current out of the driver? All modules are the same using 1400ma drivers. I have the pots installed on the dimming leads. The pots range is 1.4 ohms to 100 kohms.

Hey, brotha, PM'd you, was wondering if you had a chance to read / your impression? Thanks!

Hi Supra,
What do you think of the CXB3590 4000K DB cutter have ? I'm not sure if I should favor them for flowering over 3500K CD :/

Trying to figure out how to calculate watts per sq cm for a passive heatsink. I know this of course all matters on what profile I get, but lets say for example sake I was looking to run a 50w cxb3590 CD on a 4.230'' or 5.88''. My idea was 40cmsq per watt? I have your spread sheets from heatsinkusa and the driver-cob sheet, but still not fully comprehending quite yet. Getting there! But still confused, thanks

Supra, I am thinking of starting small and doing a PC case grow, with a canopy of 54cm x 23 cm, height of space of 50cm. What LED config/setup would you recommend, I've been thinking of CBX3590 CD 36v @ 700a?

Hey Supra, trying to build a 10x cxb3590 veg light running at 1400ma, and was planning on using the arctic 64 plus cpu coolers.. Problem is, everyone seems to be out of stock on them. Do you have any other options to your knowledge that work with the 3590s? Right now I'm wondering if I need to put in another order with heatsinkusa.

I have a queston.
Can I use ideal solderless with kapton tape?
Seems like cob isnt touching HS, maybe bolting down is required to make it touch?
