So I'm looking to do a little experiment where I supplement my COBs with a string of a few different colors of monos. The ones I'm interested in all seem to run at the same current of 700ma which makes things easy. The different monos have slightly varying foreword voltages @700ma ranging from...

@TurboTokes I have to tell you, this is AMAZING!! Such a clean and organized build. I have been really struggling with this and was at my wits end when I stumbled upon your post. The way I've been attempting to make a system was to use RainBird irrigation polyethylene semi-rigid tubing, and...

@Ares2389 You're 100% right. I found this out today when I spoke with the power company. They don't even manually read it anymore, they just drive through the neighborhood and ping it as you say. I looked at the meter and saw that lock ring with what looks to be a microchip encased in plastic...

Anyone have an idea for a quick type of lock or diy enclosure I can put around the meter so that it's readable by the meter reader guy, but not accessible? (Does the meter reader guy have to physically touch the meter when they come to take a reading e.g. to reset it for next month like a car...

The paranoia bug bit me hard today!

Yeah I'm gonna opt out for sure, and if they ask any questions I'll just tell them that I don't want anything on their grid that's hackable (I've read that these smart meters are vulnerable to hacks). Wow that's crazy, they just installed a meter without telling you or giving you any say in it...

What a timely thread. I just got a notice from my power company saying they are upgrading all meters in my county to smart meters. I honestly feel sick over it. They do give you the choice to opt out. You call a number and fill out a form and have to pay a $10/mo meter reading fee because they...

Oh wow haha, I guess I was way off about your preferences lol! Thanks for confirming! I'd definitely prefer more of the smaller voltage COBs! How do the cxm22 and 1212 stack up against each other PAR-wise? I believe you gave the edge to the cxm22 but their spectral chart isn't super clear so...

@CobKits I'm assembling a Citi COB light setup I have noticed that you tent to favor the 1818 52v COB over the 1212 36v version , just curious as to why? (maybe better efficiency) My thinking was that having more COBs with slightly less output would give more even coverage and a slightly wider...

Wouldn't you need a minimum of a 52v driver for the 1818 series? Does such a driver exist? Mean Well (CV) drivers seem to only go up to 48v Can you still wire in both series and parallel with constant voltage?

@89ers, I was wondering this myself and figured the answer would be what you thought. Thanks @CobKits for confirming!

I think I got it. So let's use the driver I currently have as an example: a Mean Well HLG-240H-C1050B Specs: Constant Current (CC) Output Current-Channel 1: 1.05 A Output Voltage-Channel 1: 238 V Output Power: 249.9 W Input Voltage: 90 VAC to 305 VAC, 127 VDC to 431 VDC Dimming: With Dimming...

Thanks @CobKits, I know you get a zillion posts a day. I think my original curiosity/confusion on the topic was sparked by something you posted on another thread advising someone to get an "A" version driver because you can adjust both voltage and current. That post can easily be taken out of...

Okay so the potentiometers on the "A" version driver have pretty much the same function as a dimmer knob that you attach separately in the "B" version is what I'm understanding from your responses. So next question: Does dimming actually lower the current from say 1.4a down to 700ma when you...

So for some reason I have only bought Mean Well "B" version drivers so far for my COB lights (maybe growmau5 recommends that somewhere in his videos...). These are constant current with dimming capability. I have a 1.4 amp one and a 1.05 amp one. Now that I am looking to add some COBs and...

@CobKits Hey, just wondering if you're going to carry the new Gen 6 Citizen CLU048 - 1818 (90CRI) in 3500K? I see both the 4000K and the 3000K versions (in both 80CRI and 90CRI) but not the 3500K? Just curious Thanks

Hey @CobKits, love your posts! This is the first I've heard of Luminous Devices, thanks for the heads up! There are so many good COBs coming on the market now, it's awesome to see. So the CXM is their flagship series I'm guessing, with the Gen 3 being the latest and greatest. You would say...

Edit: Okay, I figured it out. So the COBs are actually 52v COBs not 36, I meant to order the 36v ones and my mouse made a mistake ;) So the moral of the story is, don't order COBs at 4am! Interestingly, I now have a HLG-240H-C1050B 1.05 amp driver powering 3 of the 52v COBs and the ZPE 1.4 amp...

Okay so this isn't my first COB setup but it's not a kit this time, I assembled all the parts myself, and it's not working. Here are the basics: Driver: Mean Well HLG-240H-C1050B [output voltage 236v, constant current] COBs: Citizen CLU048-1212C4 36v (actually it the Fv is 34.6v but let's...

Do we know if Advanced is using the exact same NPK as GH and just adding aminos? Is it the same formula?
