DQG 26650 Triple Generation II Pocket Light coming Soon

Same with others, I prefer 1/2 second, but 1 second still better than version 1.
180 seconds on turbo vs 30 seconds. Now waiting for the final price and may be additional discount for promotion :wink:

Gen 1 is one of my favs…

Gen 1 Gen 2
On Momentary Push 2 Second Push
Off 2 Second Push 1 Second Push
H2O No no no! Water-proof (glowing) switch

Does that sum up the difference? Did Gen 1 have copper?

I’m prob not going to make the jump. As much as I despise the 2 second ‘off,’ a 2 second ‘on’ might be even more frustrating (How do I turn this thing on? versus How do I turn this thing off? from my wife).

What is the configuration of the LEDs in there? If in parallel, doesn’t the Vf of the G2 level out around 3.25? So why the boost driver? I honestly don’t know, not trying to be snarky.

Oopss… +100

I have the original, and the only problem with it — a significant one in my experience — is that it gets turned on easily whether in pocket or pack or hanging on a belt hook. I’ve been trying to come up with a rotating shield for the button. Maybe mine’s just unusually twitchy.

Is there a retrofit to put an O-ring under the switch to water proof the Gen1?

Nevertheless, it’s my first choice to grab at this point, to take out any time I need light outdoors.

Ditto.
I turn the tail to lock it out, but this means 2 actions to turn it back on.

Hmm there must be some way to hack the on off durations ?

Ric is behind development, so he probably could get that changed, but there's no reason to do that if you guys are going to buy it anyway.

The Gen1 has LEDs in series. This is the only single cell boost driver I know of that will do that (it will also run a single MTG2 from a single 4.2v cell, of course, but there's no way to fit that combo into the Gen1 host unless you just make it a mule).

I won’t be buying this one, i can’t see any major improvements besides turbo. Have I missed something?

Hey comfy, what about this At only 14.3mm in height, I’m pretty sure you can find a way to cram it all in there… Seriously giving it thought myself. The triple optics are what, 11mm? Not sure which optics this light uses in stock form, might be even taller.

Things getting a bit more interesting?

My bad, the 10507 is only 6mm tall…

Copper MCPCB, shorter long-press times, new outside design. If you can't see any difference you aren't looking.

Yes overlooked the copper bit.

THe press times have been extended. Old - instant on 2 sec off. New - 2 sec on 1 off. +1 sec overall.

I'll be getting one, for sure.

which price are you planning to call?

I’d prefer instant on/off and hold to change modes.

I don’t really understand the design choices behind this light. Maybe its just me but if you’re going to have 3 min of ~ 1200 lumens as a max output and 500 lumen high, why wouldn’t you use a single XM-L2? Then either make the light even smaller OR keep it the same size and have a nice reflector in there.

Or if you wanted to keep the 3 emitters use 3 Nichia 219s. Just my ideas. Maybe others prefer the XP-G2.

holding the switch for on is to prevent the accident on in your pocket… DQG 26650 is designed to be a pocket flashlight with the compact size… Shorter off makes it much better to operate now.

We also tried 5XPG2 and 7XPG2, but the beam is not as good as triple xpg lens.

Why not use an XML2 emitter with a reflector? I think DQG Triple is a floody light with a not-bad throw, it’s different with normal T6 flashlight of a narrow hotspot…

Triple XMLs is a good idea, but we have no luck to source back suitable triple XML lens.

Ric

We will shorten the on for 1 second… Hold 1 second for on…

Thanks for the advice! :slight_smile:

Ric

WILL BUY ONE NOW :D!!!

Groupbuy discount etc etc!

I think/thought ryanferg realized that and was asking why it was done that way. I suppose one good reason to do it this way is that High and Turbo should remain just as bright all the way through to the end of the battery’s discharge. If a parallel setup was used with a DD or linear driver the Turbo brightness would be markedly reduced when the battery was partially discharged, due to the battery’s voltage sag under load. In fact this is very likely to be true with a buck driver as well, even if it had low dropout - voltage sag under load on a partially discharged battery would keep Turbo from measuring up.

In addition to what Ric-CN said there are driver considerations here too. Since the Vf of a single XM-L2 is so close to the battery voltage it can be difficult to provide the same output levels throughout a discharge. Specifically the Turbo. There is simply not an appropriate buck/boost driver available that can generate a bright Turbo for an XM-L2 using a partially depleted 18650 or 26650 battery. A standard buck driver will lose brightness on Turbo fairly early in the discharge - for an XM-L2 running on a KK cell I’d expect the turbo to get less bright after you’ve discharged only 25% of the battery (eg you have 75% remaining but you can no longer get maximum brightness)! [That’s assuming a required 3.5V forward voltage for 1200lumen output and a pretty conservative/generous 0.2v dropout from the buck driver.]
