I figured that would be the case, regarding heat and it looks like it generates hot spots with some pretty uneven light distribution. Brand new, still in the box units were/are being sold at $65 each direct from their headquarters in Portsmouth NH. I ended up just buying 24 of the Thinkgrow-Ws...

any issues with it? noticable flaws? I'm guessing it wasn't the "game changer" they were touting it as, considering their grow light division was recently liquidated, but were you able to pull any nice grows with it, comparative to what your using now?

So, anyone have any updated information on how these have performed for them? Anyone that had them from a few years ago still using them? I can get them at a ridiculously cheap price, so I'm very curious to know. I'm running a room using 256 luminous cxms @68 watts each and looking to upgrade...

They are actually a fair bit brighter... You can't see them from the pic, there are 4 rigs in the back right section. The ones you can see that have the heat sinks are my CXBs. I'm hoping in this new room, the chilled ones will provide better results, so the jury should still be considered out...

Not even remotely. I wish I had purchased their blue pucks for half of the rigs I have. I've used these chilled rigs over 3 grows now, and even my older CXB 3590s driven at similar wattages/sqft perform better than the pucks. The plants just don't see to like them nearly as much, and this is an...

Didn't end up bothering with remote dimming afterall... Found WiFi remote timers on Amazon for $8 each, (rated 16a and 110/220v) and they have been working flawlessly for the last 37 days running 2 light rigs each (each rig consists of 2 bars of 4 cxm22s @280w each, for 560w per plant). For...

Plenty of info using those keywords on running a couple drivers, but not 40 running off the same one. I'd assume one would have to use multiple contactors in conjunction, but I was hoping maybe someone already laid out some groundwork on the subject somewhere.

Hey, so, not sure this is the most appropriate place to ask this question, but I'm looking to automate 40 hlg-b series drivers to incorporate sunrise/sunset functions using the dim to off function to mitigate both inrush and humidity spikes, as well as easy and consolidated timer control. Has...

NM, figured it out. One of the holder contacts was ever so slightly the cob contact. Sheesh, forgot how precise those things need to be tightened down.

Well, I'm a little stumped here. I've wired up a module consisting of (4) 36v cobs to a b series hlg185 1400, in series, wired correctly, and nothing is happening when I plug it in. The dimming leads are currently taped off. I've tried all six of my new drivers to this module, all failing to...

Quick question... And I thought I had come across the answer sometime back when I didn't have the question, but now for the life of me can't find it.... If your using the B series drivers and are not currently using the dimming function, what do you do with the dim leads? Or do they have to be...

@wietefras, That's somewhat distressing about your friends sales experience...I tried to amend my order to include more dimmers before finalizing the final invoice, but Jerry actually told me that I wouldn't need additional ones, as the one I ordered was enough. What I'm referring to when I...

OK, so to clarify, I don't need to wire any resistors into anything, right? Would the easiest method of wiring the AC lines and dimming leads into the dimmer be something like a couple of terminal blocks?

Hey, I was hoping someone here has experience with it can weigh in on the capabilities of that dimmer that Kingbrite sells. It's called ZK-link and comes with a remote, and runs about $14. Jerry informs me that it can run multiple drivers, and assured me that it will run the 6 hlg-185h 1400b...

How favorably would this compare with the more standard approach of fan-on-heatsink? Say I were displacing 50w of cob (so at ~56% eff, that's what... 22w of heat?)... What sort of wattage draw are we talking to run that cob acceptably cool? Will condensation issues be a factor when running...
