Probably a simple answer/cold weather help!

Did you by any chance check the voltage on them when light died?

Do your flashlights have low voltage protection?

I have a malkoff collection, I use my lights specifically for winter weather. This year I bought a md3 and hound dog head for myself, wife uses one with AA lithiums… I used lion and it stopped working in the cold weather (probably about 8 degrees) like completely stopped not a dimming. Is this a trait of lions and if so what the hell is my solution for extreme temps, I'll use my torch for hours ice fishing and hiking in the winter I can't be stranded on a mountain with no light… is it a flash light defect or a trait or lions and again what is my solution ?

May I suggest that you get a headlight with a remote battery?
Where the battery/pack would normally be on the strap at the back of your head, lengthen the battery cable, and carry the battery in a pocket under your coat. Your body heat will keep the battery warm and functioning. Certainly carry spare batteries, and a back up light (just in case you pull the wires from the pack or light).

Thank you for all for the constructive comments, I am going to try several of the mentioned fixes

This thread has some specific recommendations regarding headlights with a remote battery.

Which Headlamps Have a Remote Battery Pack

Hi, I've been out of the lights/headlamp loop for a while and need a recommendation. My son needs a headlamp with a battery pack that can go inside his jacket to keep it warm. Preferably AAs, but 18650s would be OK. He's in the Brooks Range in Alaska running dog sleds and will get...

Stop using a metal body flashlight in cold weather.

Not understanding how a plastic body would make a significant difference solving klip88's issue. As far as hand comfort, not sure how much a difference there either. Wear gloves when it is cold. A powerful flashlight on a higher setting gets warm and can be utilized for hand warmth.

In the same way polymer lights don't allow built up heat to readily escape a warm polymer light will stay warm in the core longer.
Say you have light B inside your jacket keeping warm while using light A until the batteries complain, light B would stay warm inside its body if it were polymer and not metal.

I have several lights, so I can rotate while hiking, however the headlight with a remote battery case might be helpful as well for over night excursions outside. To the person who said they use a hound dog in single digits and no fussing i don't know what they do but I've used m60 head and hound dog head and high draw= battery fussing. I am outside in single digits and negatives for sometimes hours.. with a 4 year old daughter I'm trying to be safe I do keep extra cells on me all the time but still annoying to change out on trail bundled up with 2 dogs and a kid…. I think maybe the polymer body is worth a shot as well.

The magic is in the primary lithium batteries. You have to accomodate that somehow.

Quickest but not the cheapest answer is rotate lights OR if it's really cold (near0F) a hand warmer pack wrapped around the light will keep it working to -20F or so. That's as cold as I've ever had to use a light. (inventory in a food freezer for a grocery chain)

Here you go. Princeton Tec Apex Extreme. Uses 8 AAs. Will work with lithium primaries. Uses a battery pack that can be placed under your jacket for warmth.

Thanks man, I appreciate the effort, I have technically run lithium primaries with the metal md3 body I have, I just would need to buy or trade for a lower output drop i like that light even if it's for back up, the other night my md3 went out in -8 weather with my kid, luckily I know my land very well but if I was somewhere I wasn't unfamiliar with I'd be in a kerfuffle
