So I've got 16 COBs in a 10 ft x 10 ft room. Canopy is roughly 7 x 7. What I've got running is 2 rails of 4 trusty dusty clu048 1818 in mixed spec of 3000k and 4000k running off the bad bitch hlg 320c 1400a. 4 on a rail, 2 rails, 4 ft each. Cobs spaced evenly apart about 10 in. on center. Then I...

Hey guys I was wondering if what I had in mind would be a good idea for a 3.3'x3.3' tent (1m2 tent). I would like to run 2 HLG-185H-C1050B (runs at 190V) with 5 CLU048-1212C4-353H5M3-F1 (Fv≃34V) cobs each. That would be, if I'm not mistaken, that each cob would be runnig at 38V giving...

Hey all, I plan on running 6 citi 1812 90 cri and last minute decided to add 2 citi 1212 90 cri to the mix for added spectrum from a 6500k led. My drivers are Mean well (2) HLG-240H-C1050's. If i was to run 3 1812's and 1 1212 off each driver would that be acceptable? Also how much would the...

E27 citizen cob led bulb. Just came across this on amazon. Any thoughts...

That's right I said it. I know, I know, Cree are slightly better, but try a Citi and you will not be disappointed. $399 retail price for 6 COB's of gooey goodness. RIU20 code scores 20% off brings price down to $319 that's $1/watt for Citi COB's. Best regards, Mike Brady

hi guys, i'm from Chile (South America) and i'm planning on building a 300W COB system, these are the list of products i have at the moment but i don't know if there is anything better/cheaper that you would recommend! 6pcs - CLU048 1212 cob 6pcs - thermal tape 6sets - Ideal 50-2204CT + Ideal...

Hey everyone, I am needing some help here.I have 3 working marshydro led fixtures but would like too convert too cob style lights.I took a couple pics of my marshydro reflector48,and pro II 80 and need help choosing which cobs i can use too convert these lights.I did a search and couldnt find...

What's up RIU. Haven't been on in a while, I've been working on a little project. :cool: The cabinet is great, but I need more space. So I've added a 4x4 tent to the lineup! I put together this setup on as tight of a budget as I could manage while still using decent quality products, and I'm...

What's up everyone! It's that time again! The next round in the cabinet has begun and I'm happy to say I'll be running some Malibu Pie by Ocean Grown Seeds. I'm really looking forward to the terps in these! After 24hrs in a glass of water, and 24hrs in a paper towel, all 4 have popped nice...

It arrived. A geyapex lm-b4 with 4 citizen cobs and meanwell driver. I popped the top off and took pics of the inside. The only issue I have is the heat sink needed to be full length and not pieces. I don't k ow how well it would cool if one or both fans went out.

Heya Rollitup. I received my test unit from Geyapex today and wanted to show off a bit, especially "under the hood". So, here's how it came, less the top foam: http://imgur.com/Q8bx1Z7 Nicely packed, there was even a small hole in the box and it didn't even come close to the unit. Now...

Hello to everyone! greetings from Argentina, i decided to make some investment and buy some cobs , here in Argentina there is no reseller of cree or bridgelux, so i have to buy them in the US, the only driver that i can get here , is the Mean Well HLG-240h-c700A, voltage output max is 357 v. The...

Hello, I have 5 citizen 1212 in my 2,29x2,29x5,25 tent, 245W ish at full power(260W from wall measure by a kill a watt) Vegetative stage just finished at 100W, now it's time to switch and an expert COB grower told me to do not exceed 200W in blooming stage because over this power amount I'd...

I posted some pics of this light in the Microgrow forum, but I figured I would share here as well. I built this light to suit my small cabinet with interior dimensions of about 18" x 38". Using an HLG240H-C700B to power all 10 in series. 100% driver utilization! I went with the 7.984" heat...

Alright fine fellows. I have just been to tend to my ladies and noticed one part of my light was out. Its a 9x clu058 1825 jobby. 3 drivers running 3 cobs each at 1400mA. So on closer inspection I noticed a wire hanging down, they are soldered as the BJB holders were very slightly out of...

In my 2x2 I want to build the best I can for as small budget as possible. Would 2 Citizen 1818's at 1400ma yield anything worthy. On calculations at full capacity they hit 800ppfd and they're like 1 parr watt short of hitting 15 per square foot. When looking at all that it seems like it'll...

Hey RIU, Lots of firsts here; first thread, first grow, and first DIY light build. Okay, I've got a two level armoire that we never use and takes up a bunch of space, so I'm going to convert it to a nice little grow cabinet so I can learn the trade and hone my skills before dropping the cash...

Hey fellow potheads. I am seeking reliable knowledge regarding LED lighting. With Cree I know the CXB3590 chips are the best to go with due to Higher efficiency than cxa chips. as for vero and citizen i dont know much and any info and experience with them you can share will be appreciated. I...

Starting a new thread for my most recent of beans that popped up. She is about week n half old. But the lights are working awesome on her. Hardly any stretch, and it looks like the nodes are going to be almost right on top of eachother. I need a bit of height on this girl but i dont want to...
