Consider a slightly-less-pocketable light for distance instead of more lumens. A few hundred lumens in a more focused beam will do much better than brute force if you’re runtime / heat constrained. Convoy L21B (cslnm) is what I use. Around 90 mins runtime on 50% (I set 50% as max for longer runtime and no heat concerns when I loan it out) and spotlights out to several hundred meters.
Otherwise you’ll be fighting against physics with heat vs runtime vs pocketability.

A lot of compact lights that claim 1000lumens and massive distance are leaning pretty hard into marketing.
