Feedback on my new COB array hanger

I would agree - they don't create enough heat to cause any concern. If you do end up remote mounting, make sure to increase the wire gauge to make up for the added distance to drive the current.



And this would be the main reason to remote mount them, the weight. But if you're hanging all those passive heatsinks, you can't be all that worried about weight, what's an extra couple pounds from a driver when you have 10+ heatsinks suspended?

I did it for heat not weight and simplicity. It just worked better for what I wanted to accomplish as well which was two bars that are one light but each dim independent of each other.

I remote mounted my drivers and junction boxes and it makes for very light weight lights. I used angled aluminum to get up and running but will be going back later and going with 80/20 when the time allows.

Lots of good information here in this thread.

Another reason I'll have mine remote.

Here's what I did for the first light on 240:

Each junction box has a dimmer and dims each bar but both bars make one light (plug). My veg light is on 120 still so I could have the timer set separately.

You might be further ahead to make 2 separate light rails with 8 COBs each depending on how you plan on setting it up. At least would be easier to manage moving it around and setting it up IMO. Those potential issues might be of no concern to you, but just a thought.

Initially I was debating building 4 individual COB racks (one above each plant). The benefit is being able to grow different strains in the same space. I might still do that. Wiring would be a little tricky unless I got 4x185's, but that's throwing money away.

Thanks first time ever if I can do this anyone can. It just takes some good planning. @robincnn & @Rahz were both a great help.

Right on! The first point of failure in any project is having doubts in your abilities, so if you believe you can do it...

Few years back I converted my garage into a pretty serious home theater. I've built two large patios for my house, modified countless walls for running AV wiring from my media closet and hanging new doors, installed breakers (including 220v), done plumbing, etc...I never knew how to do any of this 10 years ago, but all the information is out there and it was easy to learn.

You just can't question whether or not you have the ability to do something. It's really whether you have the ability to learn to do something.

Sorry, I didn't mean to sound like I'm bragging :-)

Me watching the "Brady-gate" Superbowl on the really big screen. Jeez, looks like I'm hiding a football under my shirt! I've lost about 30 lbs since lol

The heat from the Meanwells is so negligible, imo... But plenty of ways to skin the cat, so whatever works for you!

I thought you knew what it was sorry. The photo you first posted looks identical to 80/20 extrusion. Amazon ships the bars up to 8 feet in length. The shipping is sort of high but doesn't increase with multiple items. Your best bet is to buy more than enough the first time. T-slot hardware for connecting them, corner brackets, end caps, t-slot covers are all available. The covers are perfect for hiding the wiring and making a chase way.

A few more photos.

Hi
Where did you get the plates that attach the heatsinks to the long 8020s?

You seem like such a nice guy. I think you need to draw less, and build more. You will probably end up building a new one as soon as youre done with the first one. I hope you share it all :) Building the light is just as fun as growing the plants. It's definitely part of the fun. Id go for 2 or 4 individual fixtures, depending on how many cobs you have per driver. If its a four-one ratio, then build them individually. If you should ever move, change space, adjust height, whatnot it will give many practical advantages.
