DIY Passive cooling with PIN Heatsinks SST120 and SST140

[Big smo]

Are they for sale? I saw it and would love a few of them. My 80/20 builds are getting pricey.

I think the one cob_nut was talking about is the ones timber might be selling or eventually selling. Looks like 1/8" alum plate with 2 diag crosses and 4 rings in each corner to hold the heatsink. Center cutout for the driver. Looked pretty sweet imo and fairly inexpensive to manufacture.

I'm a noob in the DIY world. Very interested in it but have a lot to learn. 80/20 is pretty cheap considering, it's the hardware and accessories that are expensive. $19 for a corner block is nuts. You can build a decent frame for 50 bucks and spent 150 on bit and pieces to hold it together.

I think that's Northern Growlight frame..?

@Big smo They had the link up for the feebay auctions in their thread then took it down to lower the price. I think it was $65 + $16 ship, then read they lowered it to like $50(?) + ship. Plus it comes with hangers and hardware now.
You can tell they got some thought into it. Perfect for the guy who doesn't have time to configure/drill/tap 6 or 8 200W units but still wants to keep the components diy.

They took them off of eBay for now though, I guess.

Please do. Thanks for the input guys. It is a badass setup. I'll have to check in often cause I could use 2 or 10

And a maximizer is 2 thousand dollars for a $900 setup from timber and these frames. Man...

The frame I was speaking of was on @robincnn 's site. Northerngrowlights. I'm not sure they are for sale yet. I could be wrong though.

*edit mevermid. airwalker linked the frame . It is the same robincnn and bobby.

Robincnn will you list the specs on the citizen cobs you offer. Wattage with the suggested drivers or efficiency? Also I see the 35 mm heat sink is compatavle with the clu48 but driven at different wattages will they still cool enough?

The link to Citizen datasheets is there on website.
120mm pin heatsinks can handle 1050ma so 4x 52V Citizen cobs with HLG-240H-C1050
105mm pin heatsink for 700ma so 4x 52V Citizen cobs with HLG-120H-C700
Efficiency detail here

Another question, do you have it a dial on your pot for the different amperages? I have yet to figure that out, as I run my cxb 3590's and 3070's wide open. I have only dimmed twice maybe. It's good to know I could ramp up the pot if wanted to 1400.
BTW, i'm really diggin' that new frame design you and bobby worked out. Nicely done.

Thanks.
Not sure if i understand your question with pot. Yes you can adust the pot to control the current and the wattage. Dim +/- open is fine.

Yes. Currently 3 pcs of frames in stock. @Bobby from Mi sent a few more that will receive this weekend. Available on website here
It does not even fit in a standard 16" wide box. So am unable to get the shipping cost down.

USPS Flat Rate "game board" boxes might do the trick. They cost the same as a large Flat Rate as well.

What are the dimensions of a singular half for the Mod-420?

The original Mod 4 was 1 big piece. We split that into 2 to make it compatible with the flat rate gameboard box. $15.75 for as many frames as we can fit. weight no issue.

17.5" length
9.25" width
