I thought it might work but didn’t know about the threads. Figured if nothing else, the carrier is good. 
That’s why I suggested a contact plate. I’m making a new driver for another light and will not use springs in it like I did with the M6, I’m making a contact plate that can take twisting as it’s the only feasible way of opening this particular light. As long as you fix the pole specific contact plate on the battery side of the tube you can twist it however you like, as the contact plate on the head side will have round “leads”. Of coarse, fixing it to the battery side is the crux, but for me it’s worth solving that rather than running 8 x 18350s.
However, a dedicated battery carrier would be even better, but I’d hate to have to boar out the M6 body. I think I’d go with a different host to start with… but of coarse, if you can boar out the M6 and provide battery carrier for it, you’ll have at least one customer for the host and carrier 
So I’ve been going through many design iterations for this M6 battery carrier / floater plate thing-a-ma-jig for the last half of the day… The cheapest, least invasive, safe, and quick design I’ve come to is this…
First, with the factory board at the tail, cut all the traces like Mike C did in this pic.
Second, remove two of the springs from opposite (diagonal) corners and replace them with a solder blob or 6x2mm brass buttons that you find at FT or MTN. Connect each of these with a mate that is still sprung with a silicone insulated wire.
Then for the hard part…
Someone (I’m trying to learn how to do it myself finally) needs to draw out an oshpark board for the front end. I have it drawn in Google SketchUp, but there’s still work to be done obviously.
The front board will look like a ‘pizza saver’ once complete, and will sandwich between the body tube and the brass driver retaining ring for the negative current path. Springs will be used on the driver side of the plate for (+) positive contact to the driver. The key design element of this setup is the four 5/16” nylon legs that will locate/center the contacts and make it impossible to rotate and short cells as it’s tightened. I spec’d out 5/16” OD by 7/16” length #4 nylon standoffs (tubes) and some oversized (#6-19) plastite type screws to secure them to the board.
is it possible to get 4022 lm from this led?
Please refer to post #274 from djozz - Cree XHP70 up to 4022 Lumens and XHP50 up to 2546 lumens - Multi-die leds.
ok that seem possible, will try to do it with many 22650 battery, will like to use 9.
what driver do you use for for the eagle eye x6?
I managed to order one of the XHP70 emitters from DigiKey.
Now I’m trying to figure out where to get a sink pad. Ideally, since I’m in Canada, I’m looking for a “shipped free” pad - which generally takes me to eBay first.
I’m scratching my head trying to figure out what has the same pad footprint as the XHP70. It seems like XML is too small and MTG2 is too big.
Am I missing something obvious?
Wights A17DD-S08 with a Zener modification. 2 Efest Purple 18350’s. And most of the tricks the hat could hold.
It’s not obvious. What you’re missing is the MK-R. SinkPAD has an existing product for the MK-R which will enable 6v operation with the XHP70.
Very pretty
Why the Xs
The two marked with X appear damaged maybe. I can see some scratches that traverse the full pad that might be at issue, Im not sure what issue that creates, but its the only thing they both have i common that i did not notice on the unmarked ones. I think DB was willing to part with some for sale/trade or whatever (there was a minimum order quantity from the source IIRC) and maybe he just wants to make sure he doesnt send those ones by mistake?
SinkPAD determined that those 2 were not up to their specs, so they cut em with a box knife and marked the X on em. I tested em with my DMM and they’re fine. I was told they shouldn’t be, but continuity or lack thereof showed them to be just fine. Beats me.
I would probably have put one sheet of 15 in a small frame and hung em on the wall if they’d left the X off and not cut em up.
BLF15 code works for XHP50 w/ SinkPAD on LEDDNA now, bringing it to $13.60. oooooh soooo tempted!
Good find. Either they have a cart limit of 10 or they only have 10 in stock. It may be best to move quickly.
Get it without the sinkpad and get it for $12.32
Good thing I have nothing better to do than moniter these pages 24/7! I nabbed one for $12.32 total. Aluminum star and free shipping. I already have a Noctigon to use.
Why not purchase it bare then? Less reflows = less damage.
Personally I figure I don’t have a lot of use for less than 3 of them until they reach approximately $5-6 bare.
