After new years I've been checking arrow like once a week looking for good deals here's what I've got to work with So far lots of strips cobs and 3535 diodes I already had the MCPCB, I reflow my own diodes when I can the boards are all Dtp, I bought over 500 xpg3 diodes for like $75 they arent the best but definitely worth what I paid. I also bought a few xpg4 and put em on copper 4 up 20mm round boards just for a lil fun

Jonesfamily7715 · Mar 23, 2024

I usually use these copper 4 up mcpcb from Mtnelectronics.com but they haven't been in stock for a while. They were like 2.35 each but like everything else gone up.

There are 36, h influx l06 strips 3000k. 88 lm301b diodes each, I have a bunch of aluminum angle bar 90° 1.5", I have 5, 8' long bars I can use and a bunch of random sized pieces. Plenty for these strips ran outta thermal tape and got some comin

Cobs are awesome! Id prefer cobs over strips personally. But we have cheap electricity. They have cxb3590 3200k 92+ CRI for under $3. This same exact cob is $73 on digikey or mouser. There are still 35 left if any of y'all interested.

Who knew a meanwell LRS 600 is up to %92 efficient for 36v and 48v power supplies? I've always used Lrs 350 and they are only like %87. That is a big difference

I cut 2 8' aluminum angle bar and screwed them together so I can fit 6 strips on them, so 528 lm301b diodes on each 4' "heatsink". I have an extra hlg-320h-48b driver that will run all 3 of these nicely.

Good deal I use these and they work well

They are so much quieter than the se-600s they were made to replace too.

Good to see someone making DIY at this day and age. What is your mounting method on those mpcbs and xpgs?

When I first started reflowing leds I used a clothing iron and a stop watch and tried to match the recommended times and temps on the data sheet, then I bought a toaster oven which works like a real reflow oven but there is no benefit, I have used the hot plates on my dab press 2 years ago, and I am still running them, it is surprisingly easy, I prefer a hot plate of some sort so I can clean up excess solder. Good quality solder paste is a must, I use mg chemicals low temp that's approved for copper and aluminum. Copper boards are easier as well.

Jonesfamily7715 · Mar 27, 2024

I can get 100 of these aluminum stars for $150 copper would be like $350., sucks I gotta buy so many but, they're also direct thermal path, and all three diodes can be on separate circuits. Id like to put red, photo red, and far red on each one. Reds are ridiculous in price though.

Checked back in to arrow after seeing this thread and came across these. Any thoughts on them would be appreciated.

Thinking about grabbing some as an all around red addition to some strips I'll be looking to build with finally. Thought the broad red would be useful, just wish it didn't come with such a 450 spike as well.

That is exactly why I bought those cxb 3590 they are 3200k 92+ CRI

Cheap old tech. Mixing cobs and strips work very well. I think one of my best plants I've ever grown was with citizen cobs.

Nothing wrong with 3200k 92+ CRI
