What do you think flashlights will look like in the future?

Think back to the flashlights of your childhood, and compare them with today’s flashlights. You can see the flashlight’s technology has made several advances over the years.

Currently, some flashlights can reach tens of thousands of lumens in brightness output, beam distance range of several kilometers, and even were added with remote control. The spot beam angle also becomes much narrower.

In your opinion, what breaking changes will happen on flashlights in the future?

- New battery technologies, meaning more efficient, smaller and more accessible batteries with more standardized norms for size, connectors and the environment. the way we use batteries will most likely also change, wireless charging will be ubiquitous, charging it self will be easier, faster and more efficient.
- We use flashlights because we need light, not because we want to use a flashlight. So light itself will be enabled through other means, i.e. in clothing, everyday devices, or even furniture. We have this already, but we still have a long way to go to bring light everywhere we need it. This might be a new form of light product that can follow a user around, or something similar. Imagine walking through a home and only the areas you are in are illuminated in the areas where you need light the most.

The theoretical ideal white light source has a maximum luminous efficacy of 251 lm/W

A future technology that has high specific energy is Li-S, with a theoretical maximum 2510Wh/kg
A 21700-size cell makes a light that is a good handheld size.
Based on the 70g weight, we can expect a 21700 Li-S battery to be capable of 176Wh

If we power our ideal white light source with one of these batteries we could get 44176 lm for 1h runtime or 441lm for 100h

We can then implement a magical high efficiency driver with built-in wireless charging (so no exposed ports) to be able to ramp up or down to any brightness and runtime desired

IMO the light would be able to zoom between spot or flood, like a led lenser light.
This would give a perfectly uniform beam for close-up work or maximum throw that would hopefully do many km distance without spill, or anything in between.

A battery, a source of light, something to shape the beam, a switch, some electronics maybe, and something that holds all this together.

Integrated bottle opener.

Unless there is some massive breakthrough in reflectors making a tiny one throw like a big one etc – well, they’ll look just the same as they do now. You can shrink batteries, you can shrink led’s but it still stays pretty much the same size due to the reflector.

queue the “smart devices are the future” laugh track of adding bluetooth / wifi / an app to anything.
aside from generational LED improvements…
maybe compatibility with other devices? I mean flashlights these days have pretty potent batteries, might aswell make it a USB-C powerbank…
maybe better / more complex zoom optics for perfectly even lighting with only the angle changing?
Also, someone could figure out how to make contacts for a twisty that don’t wear quickly and stay flicker-free.

I just hope replaceable batteries (lithium and conventional nimh AA/AAA) and high CRI don’t go away!

Graphene.

Graphene batteries are going to change flashlights, and change everything else on the planet with batteries, immensely.

we will be able to run the UI (think anduril v10) without having a button on the light.

Pretty much, no matter what, buttons will go away.

Touch capabilities on devices improve every year, and are added to more and more hardware every year.

so i’m thinking in 5 years or more, there will be no need for a button at all. you just slide your index finger up or down on a specific part of the battery tube to increase/decrease brightness, change settings, etc.

Long runtimes (6 hours) on AA at atleast 190 lumens, USB-C charging.

Hopefully not.

I was excited about our new TV set with sensor keys. That was in the 70th Big Smile . Up to the present day, this touch technology has repeatedly proven to be unprecise and input is difficult to interpret. Its success is based on cost reduction in (for? to?) some part. Of course, something like a tablet PC needs touch input. But we all know we should be careful grabbing it since there’s no tactile feedback about where you touch something.

Real keys are expensive, but they will persist on any kind of keyboards and panels where you want to ensure proper operation.

Ok. Come on, say it: Unheard is just a luddite.

Smile, you cannot kill them all.

besides the lack of tactile feedback, capacitive buttons will always need a bit of energy to operate. I’m certain it would suck a battery dry in at most a few months. And how is it supposed to tell your leg from your finger when it’s in your pocket?
no, we need tactile, durable switches. and maybe even more than one for a flashlight.
Or a small touch-enabled surface for intuitive touch gestures while on, in addition to a button.
Placement would need to be well-considered in terms of practicality. And it would require quite sophisticated gesture identification. Also I would ensure you can feel the touch surface / handle the flashlight very well in the dark.

They will look as they always have, like Rockets, Dildos, or Clubs. Take your choice.

This is a very philosophical question.

In my opinion, I really cant see much change happening. I think flashlight technology has either peaked or is close to it. We have gotten to the point where we burn our hand from the heat. So what would be the next step? That we burn our entire arm?

I think we will have a greater variety of LED’s , I think batteries will improve. However these advancements are evolutionary and not revolutionary.

To conquer heat, we would have to have a metal that does not conduct heat at all. Does it exist?

The real areas of improvement would be in an interface. Operating the Andruil interface with one button is equivalent to trying to operate a computer without a monitor. So programming a light from a computer would be a huge step in the right direction.

I don’t know if anyone on this forum is familiar with Baofeng radios. These cost as little as $20 and are programable with a PC interface and a free program. Yes you can still program 500 channels by hand and it would take you a month but with the program it can happen in minutes. This is the technology our lights can use.

three things:

1. a power source (battery?) that charges itself by RF signals which reach everywhere.
2. a form factor resembling a paper clip or safety pin and weighs about the same.
3. a cost approaching “give-away” status for anything under 500LM.

My dystopian point of view...

  • lithium resources in Bolivia will soon be exhausted
  • stock market value of natural resources like aluminum will explode
  • war for resources has just begun, political destabilizing is imminent 
  • electrification of vehicles is not sustainable 
  • Soylent Green™ is people!

So, what will flashlights of the future look like?

He’ll, if aluminum becomes more expensive than copper, perhaps they will all ship in copper.

I’d like to see the shake light make a comeback with newer technology. Cash

More flashlight powered by body heat would be interesting if the planet is going to keep getting warmer anyways.

3 Space Needles and a Nazzi Magnetic pulsar ring?
What is that?

I see now, World’s Fair leftover stuff.
Cool for it’s day though.

Humans will evolve faster than the torch. Soon we will be able to see in complete darkness.

Batteries will be getting smaller and more energy dense, so I see a shift towards smaller form factors. Reflectors will gradually be phased out for optics of various kinds, and LEDs will get more efficient with better cd/mm² so you won’t need a big xhp70.2 to efficiently make 5000 lumens and throw far. Drivers are also improving. I think we will see more buck/boost drivers soon.

People of the future will not be able to see anything clearly farther than 70cm. So, all they need is a smartphone camera light. Big Smile
