Sinkpad LED Circuit boards ??

I’m looking at buying some Sinkpad circuit boards. If you are aware of these new type of circuit boards, they have a direct thermal path and are superior to MCPCP, ALPCB boards, ect. You can go to their web site to find out all the info on the boards and the new technology. (I am not affiliated with them in any way.) I received some samples, they seem pretty awesome.

If there is a thread about this new PCB board on this forum somewhere, I’d like to go look at it.

I’m open to buy extra to sell, and/or, sell LEDs mounted on the new boards. (I have a flow solder station. Can mount LEDs to the boards, or dismount LEDs from other boards and remount.)

for his wonderful emitter test threads. His latest one (here) includes comparisons with regular stars and with SinkPAD Copper boards for XM-L2, XP-G2, and XP-E2. Really impressive stuff!

There are multiple threads about SinkPAD boards on BLF. There have been group buys and VestureofBlood sells them for XM-L and XP-G. nitro had a custom run of 16mm SinkPADS made for XM-L and XP-G using artwork that the community inspired and I designed.

SinkPAD modified them a bit (removed BLF), but here’s the basic design that was used.

Here’s a link to the Nitros thread mentioned above. ^

Wayne are u going to be using these in any of your lights?

Also, besides VOB and nitro, IOS will be selling SinkPAD equivalents by beginning of May, Hank says. They are currently listed on his site as out of stock.

Correct. Here is my review of said product. They’re very good - In some ways better than SinkPAD.

Of course I’ll use them. I can try them out in the EDC-XML-R. It does not have any overheating issues, the circuit regulates at maximum 2.8A. Might keep the LED at a cooler temp, though, might squeeze out a few more lumens.

The board for the MT-G will be interesting, since I do not have a flashlight designed as of yet for the LED, and it runs at max around 6v for approx 1500 lumens, probably it can be pushed a lot harder to a much higher level than expected. I do have a few MT-G, and I purchased some of the normal star boards for them, but I also have a few sample sinkpad boards for them, and will experiment when I have time, see what the highest power level I can run them at.

I wish I had these boards in the past, I could have really used them. Well, I guess I can use them now! :slight_smile: There has always been the limit of power to the XML, and with these new boards and the newer XM-L2 LED, should be interesting to explore the higher levels it can obtain.

I have a few sample MK-R boards too, so, might experiment with them as well.

I have had the idea in the past to make something similar to this board, but, kind of hard to do so, and no time. I’m really glad someone has finally done it. It seems to me eventually the entire industry will pick up this technology, it would be stupid not to.

For all the replies, thank you. I appreciate it.

Thanks,

MT-G2 will do way way way WAY more than you're thinking.

And that's just on the Cutter 20mm aluminum boards. Extrapolate from that what it will do on a copper pillar or similar and at 6 or more amps...

I thought so, was just curious as to what lights you were going to use these in.

My EL Briuser has already been updated with cut down cu sinkpads and dedomed hiCRI XM-L2s. Nice warm tint and much increased throw.

+1 - Nice mod!

Not sure at the moment. Still giving it some thought.

I have been considering doing this, with the new boards. In the first Big Bruisers before I had my own boards designed, I cut down 3 boards to make them fit together, and later used 16mm boards. I could do this with the Sinkpad boards, or, 16mm boards might work.

If Sinkpad comes out with a triple XML board wired parallel, I could use it. I do not have the resources to have them made at this time.

However, the flashlight would get hot and would need to be powered down before the 20 minutes are up. Presently I have been using a minute amount of resistance in Big Bruisers, and probably this could be illiminated, to pump it up quite a bit. Then the batteries will need to be up to the task, and the moli 26700a would come in to play to pass up the other ICR or INR or IMR batteries.

There has been the limit of heat transfer in Big Bruiser, the new boards would probably remove the limit.

Of course, I’m looking at the MTG LEDs right now, considering what I can do with them. This new board does open up new possibilities, removing the heat transfer problem from the equation. :slight_smile: What will be coming down the pike?

I just noticed that International Outdoor now has their copper boards listed for sale, with a ship date of May 15. I purchased 5each 16mm XML and XPG.

Looks like they have 16mm and 20mm boards for XPG and XML with around 300+ in-stock for each type.

I'd be in for a stack of the 3 XML boards in parallel if you get em later on Wayne.

+1, 3 XM-L boards in parallel would be amazing. Hank, if you want I could send you some gerber files (which were meant for use with FR so they would have to be modified by removing vias if you were making metal pcbs) that have everything properly placed for use with the standard 20mm triple optics.

Are there 20mm triple XML optics?

No, but if you dedome the XM-Ls the optics will work.
