Awe yeah!

Nice to see you figured out how to get the 22" heatsink/channel to work out!

I might add a brace or two across the frame, depending on how sturdy the strips are.It'll give you something to mount your driver on as well. Frankly though, I just hotglued my driver to the back of the heatsinks because I couldnt really drill it into them.

What driver are you gonna power those with?
The sinks are glued to the angles with RTV. Probably not sturdy enough to support the power supply - that will go on a shelf in the top of the cabinet, like all my others.

If they come loose from their own weight I'll just pick up some JB weld.

They will be powered with a Meanwell LRS-150-24 CV power supply at a little under 150W. Gotta give it a little room because the power supply crowbars hard when it hits the current limit, instead of just racheting the voltage back like most.

Ah good point. Yeah, the silicone probably won't hold up a driver. And you wouldn't want to use that particular driver inside the grow anyways, so good on having it outside of the space.

The silicone should be plenty to hold up the strips, though only time will tell.

I used it with my other strip light as well, but gravity is not working against that one. We'll see how it goes.

That first build of mine is all pop riveted together including the strips to the channel. Not a single screw
One of the reasons I went with the 24" heatsinks was to be able to turn the angle flat on the bottoms to support the bars themself, that way I can drop in extra bars of strips or single diode strips of supplemental chips in a modular frame. Molex plugs on the ends and I have a custom unit I can use to experiment with.

Yeah that's how mine is set up. I can just drop on a strip+heatsink onto it and the L frame supports the weight. Obviously would want to secure it on there too though so it doesn't slide around haha

Do you need a special tool to drive in rivets?

Yes. a rivet tool available at any hardware store.
You just have holes drilled in the side of the angle and use pins through the holes to lock into the fins of the heatsinks.

Yeah, I meant to do that, but had a brain freeze when I ordered the heat sinks and put in 22 inches instead of 24.

So you have some hanging off the
Rivet guns are cheap. Every man should own one.

I'm anal, so I like drilling and tapping...
Not much meat in a 1/16" thick piece of Aluminum to hold any threads. The units running heatsinks are all tapped and screwed though.

Nice, I still have to start sawing up my frames for my next light.
Some speed weed grown in the light on the side of my Samsungs.
Cutting was rooted for two weeks and in the tube for 2 weeks so far.
The flower is about the size of my thumb.
 
What is the difference between your model samsung strips vs the model led gardener has for his 3x3 build? LED has
1510-2221-ND and you have
1510-2217-ND.. Thanks.

I used the exact same strips from the second 3x3 build LEDgardener has, not sure why the numbers are any different. The only thing I did different really is use a mix of 3000k and 3500k whereas LEDgardener has only 3000k for those builds.

Ah I see the difference now.. Its the forward voltage and flux.. What does this mean? One is higher than the other? Is higher better?

Well he has a 3x3 build that uses the double row strips, and one using the single row strips. Im using the single row strips. The double row strips have twice the forward voltage because they're twice the power (so therefore twice the flux as well). So if you went with the double row strips, you'd only need 5 strips instead of 10, and you'd use the HLG-320H-48 driver instead of the HLG-320H-24 driver.
