Im thinking a tint shifting multi emitter light like the Sofirn IF25.
Perhaps E21a based, the obvious firmware but most importantly, a proper efficient buck/boost driver or similar.

I really think if we were able to get 8 x E21a of say 4500k & 2700k with a decent 5A driver it would be something very special that EVERYONE would want at least one of. The rosy tint would be amazing, almost everyone could be happy with the CCT and the output would actually be decent. If we can get a highly efficient driver into it, it wouldnt need to be “THAT” big to sustain a couple of amps and turbo to 5, assuming we arent dumping the excess voltage out in heat like normal.

Ive reflowed different 219b 9080 emitters onto my IF25 and its an amazing concept i truly think people would enjoy having if they saw it in action. The driver is terrible though.

Yes. I love the novelty of tint ramping in IF25. Maybe a tint ramping KR1 mule? I would go with extremes like 6500k and 2000k though because combined it is super rosy and has extreme low duv of -0.0128 It’s Nichia sw45k lovers wet dream.

I love a rosy tint as much as the next guy, but -0.0128 is too much for me. I’ve played with minus green filters and it gets pretty yuk.
I also wouldn’t want two emitters that I wouldn’t be ok running on their own.
6500k is too cold. 2000k is also too warm, but it’d fun. I built one and I enjoy it, but not as much as a super rosy 2700k with a minus green.
Obviously there could be a couple of options anyway.

I think tint ramping done right is a goal Worth aiming for!

Double E-Switch would be fine for ramping up&down fast.
Pressed hold contemporary for enter on Anduril options cfg.
I think it would be more ergonomic than a single switch

At first I resented your comment, then i thought.. you are right. I really, really like the beam profile of the FW21 Pro, and I know part of that is because its high lumens. I also like the design of it too. But i use my lights, everyday, outside and what I would really like is something with the beam style of the FW21 Pro but that could sustain decent outputs for minutes, like 10+ minutes, I don’t know.. whatever is reasonable. Maybe 3000 lumens of usable performance? maybe between the size of the Amutorch XT45 and FT03 (First lights that come to mind)? So it’s easily usable/carry-able but also has some mass to be sustainable. Maybe it even has extra copper attached to the driver/mcpcb for heat sinking? Maybe it’s not even that inexpensive? And maybe 4500k-5000k. Who knows. Id pay $100+ for a solidly machined and designed, “smaller” light in a realm like described here. Definitely. And finally, maybe this light already exists and im a moron. So if it does, please guide me. Or you could tell me just run the FW21 or FT03 at 60% output and don’t be an idiot. fair enough, ill accept that too..

This thread was a good read. A number of solid ideas that I’d be willing to buy.

I especially like the double-barrel shotgun design with two emitters (one throw, one flood).

Can’t wait to see what else emerges.

You’re looking for the BLF Q8. Maybe something a bit smaller can sustain more lumens if you’re using 50.2s or 70.2s but that’s roughly the kind of size and mass you need.

Thank you, I’ve seen that light around but have never given it a serious look. I don’t know any specs. I’ll research it, must be a video of it online, thanks again,

I voted multi-head.

I'd like a simple & robust, single-cell tail clicky tube with:

1st choice - 18650

2nd choice - 26650

3rd choice - 21700

capabiliy.

 

Typical head selections of flood & throw, with high CRI availability and selection of color temps.

 

A 365 nm UV head with ZWB2 filter.

 

This next one might be too far out there but, as long as we're spitballin':

a green laser head

a red laser head

I created some simple designs:

Design 2 can be used as a headlamp and as a normal flashlight. I like the idea of having throw and flood in the same flashlight. USB Type-C port would be also nice to have.

Awesome, thanks! I checked it out, sounds pretty sweet. Of course I’m leaning toward the SP36 even though I’m sure it doesn’t dissipate heat as well as the Q8.

Side note- I voted for multi emitter thrower. Reason- I just received the Haikelite HK04 SST40 and it’s awesome. Spill and flood due to 4 nice strong emitters. I would love to see some more solid options like this especially from this forum. I know the q8 is similar but the throw on my hk04 due to the deep reflectors is amazing. Makes it’s a great all around light with great battery life.

Also – I vote for 3 18650’s not 4, seems nicer on the hand. Ideally though (2 or 3) 21700. I was really against 21700 at first bc it was just another size battery to buy but now that I’ve beeen using them theyve grown on me.

3×21700 is pretty much the same diameter as 4×18650 (eg, a Q8), so it’s not “smaller” like 3×18650 (eg, a SP36).

Don’t believe me? Using standard circle-packing formulae…

  • 3×21700 → 2.154 × 21mm → 45.2mm
  • 4×18650 → 2.414 × 18mm → 43.5mm

or a difference of 1.7mm, or about the thickness of 2 stacked dimes.

I’d go 3-21700 just to have something different.

Yea, I didn’t doubt you. It’s a good point, so I guess it’s all the same unless there is only a 2 × 21700 made (maybe weird in parallel). Although couldn’t 3 × 21700 have more mah’s than 4 × 18650? Approx 15000mah vs 12000mah (considering amperage of both is similar meaning 4 × 18650 could be 14400 mah but with lower amperage then the 21700 @ 15000mah). I don’t know, maybe that’s not ever true.

You could have an over’n‘under like the EC4GT, which is hella nice and shouldn’t be too obtrusive using 21s vs 18s.

But as I mentioned elsewhere, it’d likely have to be cast, just like the EC4GT, else you’d be milling away more’n half the block anyway.

EC4SW is still available atleast in AliExpress which hosts good old MT-G2. That is probably my favourite from EC4-series. Too bad I really dont need it anymore, but that led sure would be nice to have.

Here’s another technology I’ve been waiting for a long time! Flashlight with replaceable LED blocks! I hope this technology will become widespread!

Sorry for my poor english.

I’m picturing that, with two separate e-switches, and two separate anduril drivers.

My 2nd choice would be a Sofirn SP36 like flashlight, 3×18650, with 4xXHP 50.2, 10.000lm, usb charger and Anduril.

I feel like we still don’t have a truly excellent tailswitch clicky AA/14500 lights that are EDC focused and customization.

What about a baton light with 4 21700 cells in line like the 6 cell MAG lights back in the day? All the baton lights I find are cheap and unappealing.

For a headlamp, I’d love to see something almost tube-shaped. Battery inside, driver and e-switch on one end, tailcap on the other end… and 2 to 8 small LEDs in a straight line along the side in very shallow reflectors. Perhaps E17A or E21A emitters. Floody, high-CRI, and a driver regulated to a moderate power level.

It’d probably be 18650, though 14500 might be feasible if the parts can fit on a smaller driver. Ideally it’d be designed to be pretty lightweight, and would come with a head strap which uses loops to fit two grooves near the ends of the light.

If there’s room for 4 / 6 / 8 LEDs, it could use two color temperatures and do tint ramping between.

Possibly also a T-shaped model with a throwy LED and larger reflector in the center, between two floody LEDs in shallow reflectors. Ramp between flood and throw in a manner similar to tint ramping.

That’s what I’d make, if it was up to me.

I love everything about this idea!!

Personal preference would be 18650 over 14500 for increased runtimes.

I agree. Tail clicky is necessary for carrying clipped to inside pocket. Also deep carry clip is preferable. Not that many lights with these physical characteristics to choose from, then UI and LED offerings limit the choices even more.

I’m seeing a lot of suggestions for an edc. SC64 with ramping. As support with ramping. Agree, an current BLF version of an every day light.

There is the YLP Unicorn… I hear it’s pretty good. The main downsides are no moon mode, and the configuration can be pretty complex if you choose to edit the advanced settings. But the output adjustment is completely smooth, and from what I’ve heard, it has the best thermal regulation in the flashlight world.

I’ve been meaning to get one and make a FSM-based Unicorn UI, but I’ve been too busy with other things.

Thanks for this input. I’ve looked into that light and the absence of moonlight is a pretty big deal for me. Still, I didn’t know about the excellent thermal regulation and that’s also important to me. I followed your conversation with the owner in another thread last year and it was fascinating. This light is back on my list.

I would like something similar in size to an Astrolux MF02, with a combination of 2 or 3 throw led OSRAM (each one with their special lens) for a 1.5 or 2 km of throw and 3 or 4 xhp50.2 or xhp70.2 for many flood lumens. Powered by 3 or 4 21700, and fan-cooled, of course with Anduril 2 (when released), with lateral button (maybe 2 buttons, but only in lateral), auxiliary leds…

Basically it would be a flashlight that could illuminate near and far, and that could maintain a good level of light without overheating, being of a large size and weight, but not huge.

Now that I have an EDC05C, I am slightly closer to what it is I want (and I feel like this is probably a better idea than what I described before. I just REALLY wish the UI was better on this thing, but it’s not unusable.

I want to have the EDC05C taken up to the ultimate level.

I want this with a better ui (Anduril?) of course. W2.1 main emitter, basically copying whatever Vinh did to make the D3Cvn have crazy throw (374m of throw, 1000 lumens). Surely that could be done in this kind of light since that’s a 16340 light. I want it to be fully-regulated so it’s efficient, buck-boost if possible. And I would stick with the quad E17a emitters for the side.

I think the best solution to get two fully-functional lights (headlamp/lamp and mini-thrower) would be a mechanical switch that switches between the side emitters, and the front emitter. Basically an Anduril lamp/full-flood headlamp, switchable to a Anduril mini-thrower. I actually use mine as a full-flood headlamp and it does great. I would shift the emitters on the side a bit to allow better use of a headband for using it as a headlamp though.

So, efficient, high-cri full-flood headlamp/lamp, plus mini thrower, running Anduril. All in one.

Most things I see on the market are low quality, with plastic gears, plastic case, fake emitters etc.

I am wondering what would be possible with modern bearings, brushless dnyamos, good optics efficient LEDs, super-capacitors etc.

How many watts can a human produce with his hand? I don’t know.

Thanks varbos for that link!
I too would love to see a modern day high-quality re-issue of such a dynamo light.

Besides, after watching the HBO Chernobyl mini-series, perhaps one of us needs to wade through knee-deep water in a pitch black highly radioactive cellar to operate some drain valves … and our favorite EDC LED light’s battery / electronics has been rendered useless?

ultra high brightness 50000 lumens, have an oscillating phase shifting variable frequency pulsed output mode.

must be handheld and ip68 water resistant.

That would be impressive and well within the capabilities of this community.

If of course you wanted a challenge.

This goes beyond the boring old “new housing design” challenge.
