Will manufacturers start making significantly more 26650 sized lights?

[staticx57]

I recently bought a Shadow JM 35 with an MT-G2. You can also get it with an XHP50 it I wanted to try an MT-G2. Really love the tint of that emitter.

I recently got a Fivemega 2x26650 C head light, and I am liking it. The diameter of the body is about the same as a Z44 bezel. It's definitely a little heavier than a Fivemega 2x18650 body, but it's not bad at all, and the body texturing gives one a good grip. Finding high-quality cells to augment my AW 26650 cells (4500 mAh) is a bit of a challenge. So, Panasonic has recently(?) come out with their CGR26650B cell but the capacity is only 3300 mAh. You can basically get that, or close to it, in an 18650 cell. Is there any advantage of a 3300 mAH 26650 cell over an AW 3200 mAh 18650 cell?

5055 mAh is roughly what a 3500 mAh 18650 would be if scaled up to 26650. There are 5000 mAh 26650s available, and they are high drain. Sure we don't have the selection like with 18650s, but what are we missing exactly?

The highest drain 18650s drain over 5A CDR more than the highest draining 26650s. The only real improvement 26650s have received is more mah. They are double in size, yet their energy in watt-hours is only 1.6 times as much. Companies continue to work on 18650s much more often than 26650s...where are the Sanyo/Panasonic, Sony, Samsung, LG 26650 cells?

Both are obsolete.

The future is 20700. Panasonic will manufacture billions of them for Tesla. LG and Samsung will then probably join the party.

What about the 21700? Last I read Tesla is going with these.

Go to http://lygte-info.dk/review/batteries2012/Common18650comparator.php

and compare a Sanyo NCR18650GA 3500mAh and a Shockli 26650 4200mAh and check 5, 7, and 10 amps and look at the results.

26650,26700 and even 32650 have a good future in the flashlight world. Over the years I have watched as 26650 tech advanced. If they were not selling they would not be developing them further.

The GA is a (poorly) cherry picked example, lol. Now compare the Shockli to the 30Q @ 20A. The 4200mah isn't that impressive anymore.

Now go find graphs for the LG HB6. 32A CDR. The mah capacity is missing, but my point is 18650s have way more R&D put into them by the biggest and best manufacturers. There isn't a cell currently that can match it in size/ah ratio. A comparable 26650 would need to be 6000-7000mah to compete.

Yes, the 18650 is a very advanced battery with much more R&D and specific markets than the 26650 battery. Still, my choice for a single battery flashlight is the 26650 because it out performs any single cell flashlight. I would like to see the same R&D for the 26650 battery, but the flashlight battery market is relatively small.

Fair enough, we all have our favorites!

Some don't mind the size of 26650s and while they do carry more mah, they still don't match the size/energy density of 18650s. Also, to be fair, I'm not sure it "outperforms" any other single-cell format light - longer runtimes maybe, but theoretically you'd be able to get more amperage pull (with help from the very low internal resistance of the 30A+ cells) out of a 18650 to drive bigger (or just more, ie triples, quads)/higher output emitters with higher CDR ratings.

Probabily will. It's a great cell and I have already been seeing it used more. I think the 32650 is next. Been seeing a few more lights made to except them lately.

 

[ven]

I only have the one 26650 light, the cooly


Fed on one of my fav 26650 food, the kinoko


iirc in the x3vn, it was the highest out of the cells tested at 9.6a............

Good for the CQvn 2500 OTF ish lumens from 4x 5000k xp-g2's anyway

Just love the size! in hand


and the huge hot spot!


Would like to see some beast 26650 lights to get in production, as they handle heat a lot better, 3000+lm is more managable for those crazy times you want to light up your world............and the neighbors

I am in the same camp about needing anything more than 3000lm. Until heat is controlled on 3000+lm battery handheld flashlights their heat is for me problematic

A lot of the time the high output for me is blasts/scans/fun/hell yeh! stuff, generally 30% of the output covers my uses for flood types. Less at night and general stuff, more in day to fight the evil of artificial lighting . As i say, its nice to have on tap if/when needed, and we all know its better to have and not need than to need and not have

3000lm does get toasty quick on 18650, even with the best cells its mins of that output anyway, more duration required, multi cell lights are the only way!. Having a light in the pocket that can light a field up. just never grows old:naughty:

I think we're already starting to see the beginnings of increased 26650 light production. Models I've been looking at (top 3 in desired order)
Klarus G20 (XHP70)
Fenix FD40 (XP-L)
FourSevens Maelstrom Regen (3x XM-L2)
EagleTac SX25L2 Turbo (XM-L2 or XP-L & uses two 26650's)
Olight R40 (XM-L2)
Olight R50 (XHP50)
Lumapower Strive (XM-L2)
Fenix PD40 (MT-G2)
Xtar D26 (XM-L U3 diving light)

Some have been around for a couple years, some have only been out a few months or less.

There are a few others as well, but mainly "Fire" brands. I imagine by this time next year, we'll see at least one model from most of the smaller manufacturers that tend to cater towards "flashaholics like the brands listed above + Nitecore, ThruNite, JetBeam, etc...

You're basically right... but show me a production model LED flashlight that runs at 20A...

Also, eFest has a 4200mAh 26650 rated for 35A continuous discharge / 50A pulse discharge. Orbtronic has a 5200mAh 26650 tested to 5010mAh @ 12A & you'll be hard pressed to find an LED flashlight that uses 44W (assuming one 3.7V cell), even the XHP70 is only rated for 4.8A @ 6V / 2.4A @ 12V

This is after-all a flashlight discussion, not a vape (or other very high discharge rate device) discussion...

 

[tops2]

From here and the other forum, I'm interested in the:
Klarus G20
Olight R50 (Pro)
Acebeam EC50

These all sound to be decently floody and can throw far enough. The main thing holding me back from the G20 is the throw sounds short compared to the other 2. To me, the R50 is missing a nice low level. Not sure what's holding me back from the EC50

Not the Manker U21 XHP 35 HI? I'd prefer neutral white and the only ones I can see so far is the Manker or the Fenix PD40.

Same here. I am just waiting for a neutral U21 to be offered by Banggood or Gearbest.

All of my three main lights are single cell 26650 and I have on order a convoy L6 (2 x 26650). My edc are two 18650 ZebraLights.
