2x AAA pen sized/shaped flashlight that able to puts out 500 lumens maybe?
Maybe these tech already exist... but not in our planet 
.
6X CREE Led’s in a small flashlight with great runtime. Oh, and the ability to have a second smaller beam out the back of the light.
do we have anything we can barter marvin the martian with?
Me too, or a 3AA.
there are some 3AA lights available, the XintdX3, ultrafire sh-3aa among others
I’m thinking more in the lines of the EA41 or the D40A.
they are 3AA?
No, but I would like a slimmer 3xAA D40A.
Round and flat lantern with 4 x XM-L2, with mixed tints for good color rendering on max and warm light on low, for 4x18650 and good diffuser on all of top, and magnet on front and back. Size similar to two powerbanks, but round diffuser and LEDs taking the place of one of the powerbanks. The magnet on front can be used, with another magnet or a metal washer, to hold a paper sheet, possibly colored, to reduce glare an make more of the light indirect if wanted. The magnet on back is strong enough to attach the light on ceiling or wall using included metal discs with adhesive. With automatic smooth ramping of the light using PIR or light sensor. Also a manual inductive sensor combined with top magnet to toggle max/min/off or ramping. Possible to run on moonlight, but if someone approach, it will slowly ramp up to preset max. After a few minutes from last movement it will ramp down slowly to preset minimum. Also possible to set to react on sudden light changes. If it suddenly becomes dark or the lantern is temporarily illuminated by some other light, the light immediately switch to max and ramp down smoothly after a few minutes. Programmable using bluetooth and Android or Apple app. Built in USB charger and can also work as a powerbank. Possible to mount in roof, on wall or stand on table.
Possible uses: Table light that automatically smoothly ramp up a little when someone pass the table or sit down at it. Corridor light that ramp up when someone approach and ramp down after. Closet light. Emergency light. Powerbank. Night light on table that ramp up a little if you rise, and no need to turn off. Tent light.
Accessories might be different shades, stands and cases, extra metal discs with adhesive, camera, chime or alarm controlled by the lantern using bluetooth. Also dimmer operating on mains, but controlled from the lantern.
I’d like to see another brilliant shape and numerical control lathe program, like the SK-58, the SS-5039 and maybe the Yezl t9.
1. Solid copper pills - I’d like them to become standard in premium lights and some higher end budget lights (like Convoy)
2. AR coated glass aspheric lenses in pocket-sized zoomies. The Jax Z1 is a nice start. Now lets see that kind of quality in smaller zoomies.
3. More electronic side switch pocket lights - I like electronic side-switches. Done right, they allow for a shorter pocket light. And they’re convenient for EDC use as long as they are stiff enough and recessed enough to prevent most accidental activation.
4. Lights with electronic switch in the tailcap - this feature if fairly rare, but it is convenient. Would be nice to see more like this.
5. Custom BLF tailcap driver allowing electronic tailcap switch - Done right it should allow use of an electronic tailcap switch as a direct replacement to a standard clicky. Preferably sold fully-assembled by RMM.
6. RMM’s new drool-worthy MTN17DD driver.
And onto some of the more exotic features….
1. Deformable aspheric lens. Saw a video demo’ing this a year ago somewhere. Lens was flat. But when a collar on it was rotated, it squeezed the lens and formed an aspheric. Could be used to make a zoom flashlight without the need for a moving bezel or pill.
2. Dynamically variable tint. One manufacturer came out with a light this year allowing changing the tint on the fly. Would be nice to see more lights with that feature.
1. Efficient and powerful 1*AA drivers built by the driver gurus!!
All current BLF drivers are for 3v +
2.Sunwayman V12A
not really flashlight but I’m hoping they would upgrade their leds to high powered cree/nichia on the video lights
Multi-emitter led chips with mixed tints and driver to give automatic control of the mix. Warm and cool. On lower intensity you would by default get a warm tint, on higher intensity you would get a neutral mix of both with good CRI.
Yes.
Changing flashlights:
Drivers for NiMH 1xAA, and for Lithium primary 1xAA.
(forgetabout the alkaleaks, of course)
Lower moonlight mode (grin)
A standard flashlight core — driver and emitter sockets — with interchangeable threads or bayonet mount on both the emitter side and the driver side.
Slip-on ample cooling fins all around that core, in many varieties.
To that, add:
Snap/screw on a battery tube on the driver side. Any available battery.
Snap/screw on a mule flat short bezel, or a zoomie lens mount, or a thrower deep reflector, or an elliptical bike light optic — anything at all — on the emitter side
Like these:
Some SLR cameras (Pentax and Miranda) had standard-enough bayonet/threaded lens adapters so they could use a wide range of other models’ lenses. Like that.
(Those are big diameter, but there are also standard screw/bayonet adapters that fit the standard old Canon and Leica thread. We could steal those, they’re ready made and very precise.
They let many other small-diameter camera lenses that came with bayonet mounts be mounted on any Canon or Leica thread type rangefinder film camera.
(Why, yes, I am an old fossil, I still use my Leica IIIc and IIIf sometimes …)

Changing the world we use them in:
Darker and clearer nighttime skies — and cleaner air — so people remember what flashlights are for, too, and what dark is for — to see stars and the Milky Way looking so beautiful in the dark
Yeah, and a virus causing disintegration of all those bright blue-white headlights.
I wish those people realized those lights make them a huge moving glaring white fogbank of dazzle wider than the road, with their car hidden in it somewhere.
They ought to feel a lot less safe when I’m coming the other way, blinded, and can’t tell where they or the road are in the electric blue fog.
mtg2 that can run off 1 li-ion
Moar lumen.
I want more 1xAA / 1x14500 hosts, drivers, and parts in general. 14mm flashable boost driver or at least a 14mm li-ion driver. Like the huge variety of 1x18650 hosts/parts we have (17mm drivers), but for a smaller cell.
I also want MCUs with more space for features, and e-switch hosts to better take advantage of those features.
High-CRI everywhere, without nasty AR lens coating to muck up the colors.
Good moon/low modes everywhere.
A wide selection of frosted lenses, since they look a lot better than DC-Fix.
More hosts which are as small as possible for their battery type. I mean, the Convoy S line is nice, but the CNQG brass lights are a lot smaller with the same battery. Also, flashable drivers which fit into those small hosts.
More bare metal hosts in general. Anodized aluminum may be practical, but it’s boring and generally scratches off from daily use.
More constant-current drivers instead of PWM.
Quieter clicky switches.
Fewer clip-on clips, more screw-on or full-ring clips.
Less mode memory, more UIs which provide instant access to multiple modes from off. Also, less on-time memory and more off-time memory.
Battery indicators or battery check modes on more lights.
Sorry, my list got kinda long.
That would be nice. Don’t even need a new MTG2… just need someone to come out with a nice 17mm boost driver.
So far, the only driver that I’ve heard of that works with MTG2 and single-cell is the driver from the DQG26650
Could be zoomed when wet.
The lens of the eye is like that. It works for about 40 years and then you get bifocals.
I don’t know how cell phone cameras focus, but one thing that was tried was a water drop in oil, with an electric field to change its shape. That wouldn’t work on a larger scale.
I have a pair of universal eye glasses. For each eye there is a pair of lenses, one is shaped so it is stronger on the left and one stronger on the right. They focus by sliding.
