@anon58740919, here is a sneak preview of your SolStix from @Baudelaire . DIY lighting with the SolStix couldn’t be easier. The SolStix is a strip LED PCB, the SolStrip, with a pre-drilled and tapped matching heatsink, the SolSink. They are designed for 1" angle, in my case I went with 1/8" thick aluminum angle. For this build, I plan to run six SolStix 5" apart. They need about 1/2" on either side, so both pieces were cut to 26". I laid everything out and checked my measurements.
Next I measured and pre-punched my holes. A bit of hint here, measure from the inside edge, not the outside edge. The thickness of the material needs to be taken into account. Instead of 1/2" from the inner edge, I did 1/2" from the outer edge. Luckily I just flipped the piece over and re-drilled the holes. I think I forgot the old saying “measure twice and cut once”, my grandpa would be disappointed. 
The SolStix come with hardware for mounting the strips to the heatsinks, but do not come with hardware to connect the heatsinks to the frame. They are tapped for M3 5mm screws. I got some M3 6mm to accommodate the thickness of the angle iron. Each screw was first screwed in lightly, giving some play to get all the holes aligned. After that the screws were each tightened to stabilize the whole frame.
I cleaned each piece of aluminum with some alcohol to remove any oils or contaminants. Using the included hardware, each strip was screwed on to the heatsink with a nylon washer.
Next step was to wire up the SolStrips in parallel using 18/2 solid core wire. Three strips on each side are wired with a wago connector, then both sides connect to the driver with another wago connector.
I hooked up the driver and all systems check out! Next step will be to solder the dimmer to the driver and drill a few holes to hang the light. I’m debating if I want to ditch the CMH and ballast and replace it with this (remote ballast), or just stick it in there like I did with the veg light.
