Hello All. I've been away for awhile but I am starting to dust off the workbench.

I bought some IMR 26650's for higher capacity in a 3c maglite. See link here

http://www.candlepowerforums.com/vb/showthread.php?t=283212

It looks like these batteries are better suit to a high power application. So I am going to sell them or build a high power light just for fun.

If I build a light just for fun I don't want to fall too far down the money hole (stop laughing).

So here are some of my parts - With todays emitters, etc what would you build utilizing currently owed parts.

Parts List

2c mag host
3c mag host (willing to cut/bore)
fivemega tail cap extention
c tower heat sink
litho camless mop reflector (willing to bore)
2xIMR 26650

I have aways made simple incan mods (rop, mag85, mag66) in the past. I think I want to go with a high out put LED mod this time.

Direct driving a LED seem to be an easy route, but an intelligent drop in with multi levels (including useless WOW level, and low voltage cut off) would be great.

I can handle modifying the host, but would prefer someone else to handle the electronics.

GIVE ME SOME IDEAS! THANKS! mansell2:grin2:
 
If I add a bi-pin adapter and phillips 5761 - I could have a quick incan build.

Would 2x26650 poof! a 5761?

What is the hottest pi pin I could drive with 2 x 26650?

check out my sst90 build with those batteries:
http://www.candlepowerforums.com/vb/showthread.php?t=259313

You will have to bore the 3 c to be able to fit the batteries. ldo10c driver is working now for months and the build has been stable. I am re making it with a new heatsink now...

2 x large capacity li-ion cells would be perfect for a Quad XPG setup :naughty:

Using a cheap multi level 8 x AMC7135 board, you can power each
emitter at 1.4A

Member Hill does a very good write up here

http://www.candlepowerforums.com/vb/showthread.php?t=274025


I followed on from Hill and build two of these suckers but I used
Regina reflectors (available from the Marketplace from member Brum)
and on the second build, member Downloads 20mm XPG reflectors


I used the Multi-sink for my builds but they are sadly sold out now
but Im sure one of the forums fine machinists will knock one up on their
lathes for you :D

Here are my current thoughts. Please comment.

Mag 2c cut down to 1x26650
Britelumens Deluxe Mag C heatsink / P7 DSWOI combo

What driver option for 3 or 4 mode multi level output? How about this one from shining beam?

I also need low voltage shut off protection.

Thanks for your input.

For Mag 1xC 26650, why stop at P7?
you could get more than 2x the throw of P7, perfect beam & more spill with SST-50+ Deep Rebel SMO: Example:
http://www.candlepowerforums.com/vb/showthread.php?t=275711

Get the Brightlumens C sink/sst-50 to make it easier.
If you want multi modes, then add a D2flex.

If you do Mag C 2x26650, then you can wire 3x MCE (2S2P) and direct drive with 2x26650 for Triple MCE. Use DX Triple Cree reflector.
Techjunkie has done one like this.
 
Still reading the forums and debating.

I want a platform that I can experiment with Reflectors and aspherics lens (or collimator plus ashperic). Surplus shed is located 20 minutes from where I live (easy to kill lots of time).

This leads me toward XRE or XPG. So I am leaning toward XPG being a flexible emmiter to experiment with.

This won't fit in a mag c, unless I'm missing something.

What should I consider about a 1x26650 mag c XPG? I also like the potential run time of 4000mah 26650 plus XRE or XPG.

Who said D2Flex doesn't Mag C?. It does fit.

However, If you aren't going for big power, then you don't need it.
For XPG, the Shining beam 7135 based driver, 3 mode/1.4A is ideal for 1x26650 driven XPG or XRE.
 
I was looking at the H6CC size (1.2" dia, not the d2flex .8" dia). My Mistake.

Any comments on XPG vs XRE? Where should I buy the emmiters?

Thanks.

This will entirely depend on what you need. If you care about re-sale value, then go with XPG. Also, XPG gives bigger & more useful spot, almost 2x the lumens at no extra cost. Focus extremely well in Mag OP reflectors.

If you only care about max throw, then XRE R2/Aspherical will have an edge over XPG. However, it can be over come:

The 100K lux @ 1meter XPG thrower:
http://www.candlepowerforums.com/vb/showthread.php?t=264722

As far as source of XPG, I've had XPG from 4 different sources:
4Sevens flashlights XPG R5: I have had quark, quark mini 123 TI, Quark mini Cr2 & mini CR2 Ti, all have green tint.
Even the Quark mini AA/XPG R4 Neutral had a slight green, not obvious thou, only obvious when next to XRE Q35A.
Cutter XPG R5: All have sort of green tint, some are worse than the rest, those I got on square 10mm board were the worst.
Nailbender XPG R4: Slight green tint, not as bad.
Kai XPG R5: Had about 5-6 of this, snow white tint, that's what I'd recommend.
I am a white wall hunter, extremely picky on tint, other's might not even notice some of those hint of green.

If you're still considering incans, the Osram 64275 works great w/ soft start. Also will work with Philips 5761 but you will have to play with the voltages even with soft start. Using a custom FM 2x26500IMRs host w/ soft-start I have put 8.34v through a Philips 5761. I'm sure the voltage under load is lower.

I have to say between the two, I like the color and brightness of the 5761 better but the 64275 is more :poof: proof.
 
I've used both of those drivers, and both work well.

D2flex is a direct drive solution with multiple output levels. Output will be very high on fresh charge, then drop a bit but remain steady until the battery ouput drops below the Vf of the emitter (you will definitely know when a charge is needed). The switch will need to be modded to momentary. I've read here that the magC switch is a bit finicky when it comes to that type of mod. Do a search to see how it can be done.

The SB driver is nice as it will provide a 3 speed constant current output. Again, the MagC switch has issues with that driver as well, but there is a simple solution provided by several here (do search).

I would also recommend a similar type of driver from user Download. Same type of 3 speed driver w/2.8A max output, however, it does not suffer form the "jumping" output since the electronics are slightly different.

Here is the latest evolution.

Mag C cutdown to 1x26650
1x IMR 26650
SSR-50 star (on order from AVNET)
Heatsink (by me)
Maglite rebel SMO reflector (salvaged from 4d led)

I still want multi levels and need help picking the driver. I am currently debating between.

Any thoughts on these or other drivers?

Thanks!

the Shiningbeam driver is great.
It also takes care of your other post re: no discharge protection, as that driver will notify you as charge decreases. I mean you'll be aware of it long before hand: "Hey, my arm is getting sore from walking around with this lumen thrower on high for an hour. I wonder how the battery is?" :)
For use with an ssr-50 you really should add a slave 4x7135 board (or even a 6x board) to up drive levels to 4.2A or 5.0A.
Best is that it's multi-level, so you're perfectly able to use 'medium' (+1A with the slave board).
Unless you sell me that extra battery :naughty:, you'll have a spare, so that's uber run time.

Edit : I just noticed your reflector and you may prefer a 2x or 3x 7135 slave: - you'll really have to watch output vs heat with the plastic m@g reflector. It's totally do-able, just be mindful of it.

I don't recall seeing a comparison of those two reflectors. Did you notice any difference in throw? I finally got the Download reflectors, but had to rip mine apart to mod the heatsink so it would fit (still have to update my build with beamshots). Not sure if the throw is any better than the LXP optics, but I like how it looks with reflectors.

I hate being indecisive. If I need to boost amperage, why not just go with 2x26650 and get the added runtime to boot.

I would like to be able to run the ssr-50 to full spec to show other the potential of modding, but I don't see myself walking around on full power. Low should be very usable for close work. Medium for walking around and high for the occasional how far can I see? I expect modding of reflector back side.

Anyway - I don't mind to 2x26650 form factor. Is this a better call for a useful build. If so which driver for 2x26650?

Thanks in advance.
