Will do! Waiting on heat sinks and power supplies. Still need to order holders and reflectors. Haven't decided on framing yet; looking at 80/20 but that gets expensive when you are building 18 units. May see what I can dig up at Home Depot. ;-) Just started new grow; hope to have some new uints...

Sweet!

Lookie what the FedEx guy dropped off yesterday...

Where did you order your stuff from? I am having a hard time finding some place with a enough reflectors in stock to build ny setup.

Great to know! I'm about to drop $1K on heat sinks and I want know they can deliver. They definitely have good prices.

Which Mingfa heat sink is that? I am currently considering 2 of theirs for my 1212's? How long did it take to get them; I have been quoted 3 weeks?

Nice! Do you have any photos of what you are building that you are willing to share?

I looked into this a year ago, but shelved because time constraints. I think a combination of raspberry pi's and Arduino's will be the most cost effective. I like the cell phone app, but my first goal is a database and website so I can start gather data to make automated decisions. Gotta gather...

I have contemplating how to build in scalability into my lights so I don't have to do a major overhaul to control them later. In the end I will have 18 individual light units to cover the room, so I would need more than 16 channels, and that's a lot wire running around the room. Really like the...

This awesome @VegasWinner , this was gonna be my next project after getting my lights built! Hopefully you will have all the kinks worked out before I get there. Any plans to create a GitHub project to share all your code and schematics? I like version control and traceability.

What is the part number, I could use something similar? Are thry pre drilled? Thanks.

Cool! How much does that thing cost?

Correct. Mid July delivery.

CDI = led.cdiweb.com Rating? I am getting the 3500K and will run them between 1.3A and 800mA (~48W down to ~25W).

Brother that is why I am going with 1212's! The way I. Am designing the setup I can always upgrade to 3590's when I find some extra cash lying around.

I have started procuring the materials to build Citizen based flower room. This includes 75 1212C's. PLC was nice enough to order a set of 1.3A@156V units. I should be able to drive 4-1212's with those at just under 200W. When I get things assembled I will let you know how it works out. I am...

My idea for using the 1.3A was to be able produce a PPFD from 1200 down to 600 so I can dial-in the optimium light for my grow. It will give me flexability (or that's my thought anyway).

I was strictly going by the specs and didn't want to assume there was any extra to spare. Nothing worse than buying 20 power supplies that can't drive your cobs.

Still working out the details. I am working with a company to get a customer power supply (dimmable) that supplies a maximum of 1.3 amps and can run 200 Watts. The standard Mean Well's @1.4 amps do not have the voltage to support 4 1212C's; there off just a couple of volts. @1.3 I can nicely...

Finally got off the fence and ordered me some COBs. 75 CLU048-1212C4-353M2K1 @ $10.04 each. 6-8 week delivery. :weed: There's gonna be some bright light in my future.8)
