Great idea!

A new P60 style light. Not the same size or models - more the concept:
- interchangeable bodies and heads
- a “pill” concept that has better heat conduction than previously
- different pills with different drivers, LEDs and features
moon mode
no more than 4 modes
coppper led pcb
thick wires
usb charging
Additional reflector or spacer if want to change it to triple led. Will be great if can make it customized triple alumunium reflector otherwise triple carclo is fine.
4AA with 4S exchangeable with li-ion, e.g. Lumintop SD10.
Moonlight mode, max 5 modes, hidden strobe or using ToyKeeper Attiny 25 driver (using good components, it don’t cost too much).
Screw in mcpcb to pill, make it flat and using thermal paste, don’t solder/glue it for easier to change led later.
Neutral white led
Good anodize, like BLF Eagle Eye X6.
Good enough tail switch.
What about a motorised zoom that’s controlled by just pressing a button and holding it down to change from throw to flood?
Having that and the infinitely variable brightness would make a great light.
A full carbon fibre light would be nice but expensive, a carbon fibre finish would also look fantastic.
A small 14500 light that takes a 17mm driver, the head should be no more than 22mm in diameter.
I might be wrong and tell me if I am but it looks to me that Gearbest are after innovative idea’s and something that would really make a flashlight better and different to the thousands that are already out there so it stands out from the crowd for whatever reason.
It would appeal to everyone looking for a light and maybe just not just us lot that look for specific improvements like a copper mcpcb, certain tints, firmware etc. :-x
1. E-cig mods have display screens for navigating settings. Why not flashlights? Put it under the rubber protector that covers the usb charging port if necessary. On my ecig mod I can scroll through power with a rocker button. Why not do variable intensity that way on a flashlight? With a screen display it would be easy to customize many features. E-cig mods do this and are still low cost.
2. Provide safety venting by having vents under the rubber button covers. If the battery starts to vent the covers are pushed aside by the escaping gas.
May be these things are already being done and I don’t know about them. I’m newly interested in flashlights because I vape so using and maintaining 18650’s. So why not have a light since I’ll always have a good battery at hand.
Flashlight with led on copper mcpcb with direct thermal path and driver with good UI, battery capacity indicator.
I desire a flashlight with a large central reflector and three smaller reflectors, so as to have both the thrower and both the flood.
Then I want a USB port to charge the battery and to program the functions.
The head shape may be triangular (as in the drawing I made, just to give an idea) or even round; but triangular, surely does not roll away.
I add with the head of the flashlight round, easier to produce
Personally, I see the value in having a light that runs on both lithium batteries and regular AA batteries. This helps appeal to more than just the lithium battery user.
So, multi chemistry support.
Also, a user interface which allows instant access to the highest and lowest modes from both off and while on in any mode would be great. One way to achieve this would be to use an electronic switch where a double click or a press and hold would take you to a particular mode.
Two head choices - one regular and one “turbo head” which is larger for more throw. (Like the Solarforce turbo head…)
Use high quality anodizing.
Like many have already said, good heat management.
Don’t use “budget LEDs”. Stick with LEDs like genuine CREE or Nichia.
When making a decision during design, don’t pick looks over function.
Infinitely variable brightness system, last used brightness memorized
a triangle head for anti-roll and NO BLINKIES
I think it’d be cool to have a flashlight with a built in USBASP programmer. You could just plug a usb cable into the flashlight and flash a new firmware to the driver without having to mess about with SOIC clips and whatnot.
Olight S2 with high CRI neutral LED and without reverse battery inserting. Cu and SS variants would be great too.
18650
Instant access to moonlight and turbo.
Strong magnet in tailcap.
Reverse polarity protection.
Pocket clip.
Lanyard.
A flashlight that can be powered by any battery. It will need some kind of mechanical mechanism to allow for different physical size batteries. Also it will need some magical electronic circuitry to detect outputs of various battery. If the battery doesn’t fit into the flashlight housing, it will have a retractable cable that will let you connect to the positive and negative terminals (polarity protected) of the external battery.
