I am waiting for a SBT90.2 behind a TIR lens like the MC13 and L17 use. A single 21700 cell easy carry with high output and incredible rang like 2000 meters 
Could a flashlight like this be made or is the 90.2 just to much power to focus at a distance of 2000 meters in a smallish frame? I am really liking the small pocketable super flooders and throwers. I ordered the XT45 last week, which is my first 90.2 flashlight, and have plans to also get the MC13, L17, NI40, NSX4 and the X9L. I like the small hotrod lights. I have had my NSX3 for a while now using the 40T and Molicel which was great and then I got the 30T’s two days ago and the flashlight WOKE UP! It’s incredible how far flashlight technology has come since I joined BLF in 2017. How far can we push size power and range? I love this site but my wife hates it lol. The future looks bright
I mean, for brief periods of time, you can give it as much power as your cell will deliver. 30T probably does alright for short bursts. I’m not sure if the range would be better than CULNM1.TG/CULPM1.TG though, and those are at much more sustainable currents. It’s just pencil-beam vs. 5000 lumens.
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,
now known as sofirn q8. sweet light.
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…
-
3x21700 → 2.154 x 21mm → 45.2mm
-
4x18650 → 2.414 x 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 x 21700 made (maybe weird in parallel). Although couldn’t 3 x 21700 have more mah’s than 4 x 18650? Approx 15000mah vs 12000mah (considering amperage of both is similar meaning 4 x 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.
Here’s another technology I’ve been waiting for a long time! Flashlight with replaceable LED blocks! I hope this technology will become widespread!
I’m picturing that, with two separate e-switches, and two separate anduril drivers.
