I gotta come back to this - the way those strips are hanging makes me feel uncomfortable. I think you should add two more cross beama they are sagging

Sorry I missed the part about not wanting diy.

Rock on! I am just so excited about building this stuff *flies away*

That light is Approx. 46,500 Lumens Recommended for 4x1 for $700 Replace 400+ Watt HPS If you build your own, this is what you can pay for led and driver including shipping. You can see you can build a fixture with over 10,000 MORE lumens for only 300$CDN plus aluminum and minor costs of...

If it wasn't for you I wouldn't be growing lettuce in my kitchen

I'm designing these for a 2x4 I'm guessing they will cost less than $500cdn to put together.

The other problem with channels is how do i mount the drivers on the fixture? Theres nothing on top of the channel to mount to. I would prefer to use channels but I cant figure out a clean solution to mount stuff ontop of them.

I cant put a bracket on the end of a channel. Im limited to 45" max width and the strips are just over 44"... unless i get a .25" l bracket

Should also add im getting the tube for 1$/foot

How do you mount to the top of an open C channel? My bars have airspace between them so not sure how I would fix them to a crossbar. Instead of using radial blowers inside the tubes ill connect all the tubes to a larger 2x4 tube and drill holes where they connect... so ill put a couple fans...

730nm put them to sleep right? The 630nm I thought were to wake them up. I was going to have both plus some high CRI monos like Growmau5 did on the quantum canopy.

So you think I dont need a fan blowing through the tubes. Its not going to cost much to do it, I think Ill go ahead and do it anyway. I just wonder what else I can do with this fixture. I feel like theres more i can add but Im not sure what. Would adding a bunch of reds make it better?

Doh! I should have gotten the B. All three of my meanwells are A - im afraid of dimming wires

Ya buddy! I think this might be a semi-permanent hookup.

Ha ha. Ok well I'm getting the tube for really, really cheap. The store lists it for $14 a piece but I'm getting it for $4 a piece, so I can't really say anything else would be cheaper at this point.

Aluminum is expensive! I like the look of flat panels better

Model APC-8-350 350mA 11~23VDC 8W

What I'm confused about is the statement that I've heard here more than once it with the constant voltage driver if one of your chips blows then all the extra Amps get sent to the remaining chips . So if your driver say for example is a constant voltage 40v driver with 4A and you have 10 40v...

Just for the record this driver will run a 4' strip at half recommended
