These might be a viable option: https://www.amazon.com/Trimless-Rec...rds=aluminum+c+channel&qid=1603130214&sr=8-34
I was thinking mount the strips on the back side of them.

I think you'll need something beefier than that. About the size of the sinks that cost more than the strips. Though anc does run his hot iirc

I DM'd him, we'll see. They don't show a wall thickness though, free returns is a plus.

I have a heatsink question, I have been researching builds on here: https://ledgardener.com/diy-led-strip-build-designs-samsung-bridgelux/
I searched the forums however I couldn't find an answer for my question. The heat sinks referenced on that site are about $60 for a 4' piece, $20 more than the strips themselves.I want to have enough cooling to not fry $160 worth of strips (doing the 4X4 build with Samsung F series). Any input would be appreciated.
Check out Tnutz

tnutz are great for builds! https://www.tnutz.com/product/ex-1010-d/ you can attach the strips with a thermal tape on the flat side and hang as you like...

I was contemplating spending some time with the drill press to aid airflow by making holes into the void behind the flat side. The design I was looking at only runs the strips @75%, so they say.

The tnutz look good, if I didn't get the other channels I'd be looking at those. Few beers in now idk, looks good though

full disclosure ive never used them. I just saw on the PCL site thats what he recommends now.
I found a slightly cheaper option out my way and if I go pickup from the warehouse I save shipping too. waiting to hear back what they are rated for ma wise. they are actual heatsinks but the tnutz looks a lot more substantial so im guessing t would be a better choice for someone who wants to run their strips really hard.

Link please? I've been looking into strips for awhile, just haven't been in a position to pull the trigger yet. I haven't done the math, but the build I'm looking at is only supposed to go to 75% current.

just saw this for first time myself other day, someone posted in another thread.
these are custom strips though so not sure its applicable to your specific strips but maybe something to learn from it.
also, i think the ledgardner builds are just recommending 75% as the sweet spot between efficiency and power. but i think their designs will work fine at more power heatsink wise, you would just use less strips and maybe will need some fans blowing across the top of the fixtures to help w cooling.

also if it's not been pointed out yet, this is from a few years ago and 75% was trying to balance efficiency with power for best value. when you can get strips for super cheap then you just buy 2x as many, we try to shoot for 50% current (or nominal value from datasheet) this gets the lm/w efficiency way higher. then you only need minimal heatsinks, or for some brave ones, none at all. if you run strips at max wattage you have such an intense light that you miss out of some of the best benefits of strips - spreading out your diodes as much as possible so that the intensity of each diode is not so bright as to bleach your leaves. this way you can run the fixture way closer to the canopy for much better penetration.

You can get basically the same thing minus the connectors for 1/4 the price

Yes , your going to need heatsinks. OR you can buy more strips and run them softer. 50% dont get hot enough to need any cooling. the ones posted in this thread for a buck each is the kinda deal you gotta find to keep the build cheap if thats the goal. (painted aluminum rails. 48" long)

this is a decent deal! the ones i was looking at were that price for a 22" section. 6x 6.6' for 87 bucks WITH a cover is a fuckin steal! The cover looks like shit as its not clear but its still a good deal. Thats 40' of heatsink WITH a cover for 90 bucks ....you really cannot beat that.

Th
The Tnutz are comparable in price for the 1" and are studier. I was thinking just use the aluminum part of the Amazon ones and attach the strip to the bottom side. Don't want the covers for our application, and I'm not sure if putting the strip in the trough would limit the light on the edges.

im seeing 5 bucks for a 22" piece. ? Thats not compareable but they are much sturdier.
