Triple xp-l 1x18650 with thermal control
if XP-L Hi or XM-L2
-moonlight mode
-hidden blinking mod or on
-side switch
if XHP
-temperature control
-hidden blinking mod or on
-hi output
More options for lights to have XP-L HI and more options for modes. For me this would be the option to eliminate next-mode memory.
A budget single AA/14500 “L shape” headlamp. Something like Skilhunt H15 but lighter and cheaper. There are not many lights like that.
Low mode of 1-lumen or less. Hidden Strobe and/or SOS modes. Genuine Cree LEDs on Direct Thermal Path boards. Temperature controlled Turbo.
Must have moonlight.
Something that can be used with AA’s or Li-ions.
Ability with a shortened tube (included) to be used with CR123a yet still look sexy, not just stumpy.
Tailstander.
Raw, rough, tarnishable finishes, be they steel, aluminium, copper, brass with metallic switches to suit (or even contrasting switches, for example steel body, copper switch)
Oversizing - at least in terms of large and mega deep canyon-like knurling, super-big lanyard hole that would take 550 paracord, oversized head and (removable) bezel with smooth and crenelated varieties included in the box.
Omni-use clips. Reverse mountable so they offer complete deep carry either head up or head down. Easy cap-peak fitting if that floats your boat. Make sure there is an equivalent clip (or the flashlight is so engineered) that the same Omni-use abilities are present when using a shortened tube.
- Magnet in tailcap
- Moonlight
- Can stand on the tail.
- Compatible AA
- Recessed switch so the flashlight doesn’t turn on in a pocket or a bag.
- Light (that would exclude things like copper, etc…)
- clip
Want/Need ToyKeeper's Bistro firmware.

A series of flashlights / hosts with interchangeable heads and bodies.
Bodies with different sized cells: 16340, 18350, 14500, 18650, 2xAA, usb recharge port, tail magnet.
Heads: single emitter, triple emitter, floody, thrower, zoomie, cool tints, warm tints, crenelated, reflector, TIR optic
Any head can be screwed on to any body. I would buy so many. Gotta catch ’em all!
I have read a lot of very good comments, so I just will pick up some:
Ah…no Moonlight for me. Nothing less than 5 lumens for me, please 
Improved srk style light with removable carry handle, moonlight and ramping, 2s2p 18650 with tail end battery replacement, square threads, thick integrated shelf, extended external cooling fins, longer head, deep op reflector, and xhp-70 emitter on a copper dtp mcpcb with options of warm, neutral, or cool white.
Strong magnet in tailcap.
18650
Warm to neutral led.
Instant access to moonlight and turbo.
Low voltage cut off
All important to me
configurable firmware through usb port, would be very useful. Especially if we would be able to flash our own code.
My dream…
-High output with one genuine CREE XP-L Hi or three genuine CREE XP-G2/Nichia placed on a DTP copper MCPCB.
-Neutral tint.
–4*AA in series with holders like Sunwayman D40A ot Lumintop SD10, compatible (with adapters) with 18650 to 32650 or 3*AA.
-Reverese polarity protection.
-One or two lateral switch.
-In turbo (supercharged) with ramping (down/up) temperature control by sensor. In lowest, minimun 5 lumens. May be ToyKeeper’s Bistro firmware.
-Instant access to turbo or lowest at any time.
-Momentary on
-With 4*AA… Extension tube set for extended runtimes like Fenix TK75.
-…
It needs moonlight mode and a copper DTP.
Real low moonlight mode, magnetic on tail
There’s been some good suggestions already.
An XHP35 HI (running off 1 18650/26650)
I’d also like a rotating head so that I could tailstand it and have it point at a 90% angel. Pair that with a magnetic tail and you can pretty much point the light in any direction. I’d also like a nice thrower with an interchangeable frosted lens (or one I can just cap on) to make it a flooder.
Battery indicators are nice as well.
BLF A6 type flashlight with 140 db alarm and 18350 extension tube.
Most alarms do not have a powerful flashlight.
On a light this size a small waterproof area. Like a pill box type screw plug chamber or something
keep emergency meds, band aids, fish gear, money, etc. could be clear lid and put a trit in there too.
could be built into a handle.
