Ran7ger...that Olight perun 2 seems pretty intriguing!
I don’t think there is a light that can’t benefit from lithium batteries in cold weather…..
Sorry but lithium ions ARE rechargeable!!

O-light perun is what you're looking for, trust me.
I love my Fenix HM60R. I don't use the top strap and it stays put perfectly fine. Uses an 18650 battery so you can swap them and also has onboard USB-C charging. Has a frosted light for up close, an unfrosted LED for better throw, and a red LED. Also has a nice big button for use with gloves. It is a little pricey, but they have sales from time to time. https://www.fenixlighting.com/products/fenix-hm60r-rechargeable-headlamp
