Trailblazer420 Posted February 26, 2019 Share Posted February 26, 2019 Yeah, I'm doing a pilot run on some C99. Running 4 x 100W chips. Still vegging though. Sent from my EVA-L09 using Tapatalk Quote Link to comment Share on other sites More sharing options...

SkunkPharm Posted February 27, 2019 Share Posted February 27, 2019 I am running 2 Bridgelux Vero 29 3500k at 1.4amps. Got them at growopz. Good price if you don't have all the tools to do a DIY project. I am running then with a 150w MH and the plants seem to like the mix of light.Sent from my VTR-L09 using Tapatalk Quote Link to comment Share on other sites More sharing options...
McB Posted February 27, 2019 Share Posted February 27, 2019 aside from rs and digikey, any local cob suppliers im missing? i need supplemental light, and thinking a single vero cob may fit in budget and heat wise Quote Link to comment Share on other sites More sharing options...

Was really interested with the Vero 29s when i made my lights, just couldn't get them cheap enough and couldn't find them locally. I ended going with 4 CXA2530s @600mA on PC Fan heatsinks. I'm now looking at upgrading my COBs to either better Cree's or some Citizen CLUs if i can find them cheap enough. My most limiting factor is the heatsinks. Anyone know where i can get bar type finned heat sinks, similar to what GrowOpz has on his site but bigger? https://growopz.com/collections/grow-lights/products/large-aluminium-heatsink-for-3w-leds Quote Link to comment Share on other sites More sharing options...

CG420za Posted February 27, 2019 Share Posted February 27, 2019 Awe @Q9550, the okes are right with DIY's, growopz does well with his LED's but something so simple shouldn't have to cost you arms and legs. 1 Quote Link to comment Share on other sites More sharing options...

CG420za Posted February 27, 2019 Share Posted February 27, 2019 Personally, if you are able to construct it yourself, I would go with that option. 9 minutes ago, McB said: looking at his single vero29 cob fixture and component pricing retail works out pretty similar assembled 1 Quote Link to comment Share on other sites More sharing options...

CG420za Posted February 27, 2019 Share Posted February 27, 2019 Yoh bru, i see your frustration. I imported an LED panel a month or two back, it took 2 days to get to customs, another 5 to get to me, so that wasn't so bad. But yeah, shipping times is a fuck up sometimes. 1 Quote Link to comment Share on other sites More sharing options...

Would definitely prefer to do DIY, love that satisfaction of growing with something you built yourself, if only parts and components were a lot cheaper and easier available. 6 minutes ago, greenkush said: Digikey send direct to your door with UPS World Saver, I've never had issues bringing in components. Have never used DigiKey but have heard good things, i got my chips from Mouser the last time and i think i paid around R150 each for 4x CXA2530's, U2 bin, 4000k CCT, the drivers from AliExpress and slapped the chips onto some intel pc heatsinks which i got from work for free.

Trailblazer420 Posted February 27, 2019 Share Posted February 27, 2019 What chips are you running man? Pre-made or diy? Here is my setup, planning on joining two antminers and run 5 chips. Just be careful, LED burn is a real thing :) Sent from my EVA-L09 using Tapatalk Quote Link to comment Share on other sites More sharing options...
Q9550 Posted February 27, 2019 Author Share Posted February 27, 2019 (edited) @Trailblazer420 That looks like it could work for me, where did you get the antminer from? I'm running DIY Cree Cxa2530's on individual cpu heatsinks, would prefer to have all 4 on a single heatsink or maybe 2/2 split like yours above. lol yeah i have been burnt by mines a couple of times as well. On 2nd thought, just had a look on google and those miners are kak expensive, anyplace i can get just the heatsinks or is it just a full miner for sale?

trichomechaser Posted February 28, 2019 Share Posted February 28, 2019 I picked up a COB from Amazon a while back. It was one of the "Galaxy Hydro" lights. They have released a number of COB setups but most were not using any reputable chips. I picked up their 2018 Edition which came with 2x CREE CXA3070. Not quite as good as the CXB3590, but I've been impressed by what this little 110W draw light was able to achieve. I run it in an 80x80 tent. I don't know if you guys know of the autocobs, the dude has a huge following in the autoflower community in the US, since he's quite active over on autoflower.net - but he ships to S.A and the lights are of great quality. The chips are Citizen CLU 48. 1 Quote Link to comment Share on other sites More sharing options...
McB Posted February 28, 2019 Share Posted February 28, 2019 Not a cob. But I reckon I have Frankensteined a decent clone light together.2 cheap ass t8 1.2m 36w attachments.Gutted one and combined74w 15k lumens at 20cmForgot I have a 50w Chinese cob on an overkill heatsync. Will chuck that in tooSent from my ANE-LX2 using Tapatalk Quote Link to comment Share on other sites More sharing options...
