I got it working :clap:. The power cord connector was screwed up which was the problem :sleep:. Thanks all for the advice, I did verify that the driver is running at the correct voltage. and @hicpic as someone who also has little to no electric AND diy experience I give you the green light that...

So if I want to check the current at the first connection in the series do I disconnect the wire to the following cobs on both the positive and negative sides of the series so that I can touch the probe to those wires? I don't understand where to touch the probes to when I want to measure a cob...

Ok thanks, I'm hoping that's the problem. Never built anything with wires before so I didn't know if that would fuck it up or not. I have a multimeter, is that what you mean by DMM? edit: I cleaned up all the exposed wire and still nothing. any tips on how to use the multimeter to check for...

Thanks for checking it out. That's the way @Greengenes707 connected the dc side on his tutorial vid so I'm pretty sure it should work, as long as it's connected properly...

Hey @Growmau5 (or anybody else that has any input) can you help me figure out why my light won't turn on? I have (6) cxb3590 and an HLG-240-C1050a and as far as I can tell everything is connected correctly. I triple and quadruple checked the +/- alternation and each connection point. Here is a...

@hicpic I have most of the parts and plan on building it this coming week if all goes well. growmau5 and greengenes' youtube vids are my main resource right now for learning how to build this, so check that out if you haven't. No optics yet for the cobs but I probably will eventually when I...

I am building this exact light. According to the diy cob calculator done by @bggrass this light will produce 88 heat watts which requires about 1500 in^2 or 31" of 5.375" profile to cool passively. I believe supra recommended using the 5.88" profile rather than the 5.375", though I'm not sure. I...

I got a response every time I pm'd eraserhead on their forum at http://www.ledgrowlight.lighting/forum/forumdisplay.php?fid=3. I am running 6 a51 w90's right now as I wasn't ready to build my own lights a few months ago and am really happy with the quality of growth I am getting and the product...

six w90's starting to fill out a 4x4 a few days after 12/12 flip.

download the latest version of java. it did not open for me at first but then after I updated java it works.

if youre trying to find something for the longer term and you need to spread the light over a space of more than 6-8 square feet, I'd say the go green is a better option because its softer driven, more efficient and has more cobs to spread the coverage out a bit. But, I like the w90's for myself...

I would go with three of those builds for a 4x4, that sounds perfect. That is the exact setup that I want for my 4x4, should be great spacing and intensity and efficiency obviously. 21 PAR W/ft^2 and 3/4 of a cob per square foot. But thankfully 400w will do ok too so if you need to save up for...

that's funny because supra literally said the opposite in another thread. you really keep grasping at straws to try and demonstrate that this is a shitty product, but it's not

the 5k is slightly more efficient (less than 1%) than the 4k which is slightly more efficient than the 3k but the differences shouldn't be large enough to determine what spectrum you get. Go with 5k if its gonna be for a veg room only, 4k or 3k for both veg and flower.

there's a thread answering your question on the a51 forum: ledgrowlight.lighting/forum/forumdisplay.php?fid=3

great post. i still don't really understand the availability of the PLC lights, it seems they are always sold out. and i personally really like the modular aspect to the w90's.

SCROG under COB and some bomb ass dank ass purp scurp... getn reeel blaze baked du

BM9AGS is making me uncomfortable with all of his selling of that gogreen brand

I got a tracking number on tuesday 10/6 and my lights (two 3k and two 5k) are on track to be delivered on monday 10/12. didn't receive any communication from them except the email with the tracking number.

I love ur tent man it's inspiring
