Score breakdown
Most emergency lanterns are purely utilitarian. The AlpenGlow 500 is the exception — it's pleasant enough to use every evening, which means it's charged and to hand when you actually need it.

How we tested emergency lighting
Emergency lights are scored for predictable output, long-storage readiness, charging options, and ease of use in the dark. We favour controls that can be found by touch, batteries that are simple to maintain, and runtimes that stay useful beyond the first bright hour.
Design & Build
A soft-touch silicone base and frosted globe give the AlpenGlow a lamp-like feel rather than a torch aesthetic. It's USB-C rechargeable and survived our 1m drop tests without damage, though it lacks the IPX rating of dedicated outdoor lanterns. A playful shake gesture cycles through colour and multi-colour modes.
Performance
We measured 480 lumens on high with an outstanding CRI of 95 — food and faces look natural, which genuinely matters during a long evening outage. Runtime is 5 hours on high and around 200 hours on the lowest amber setting. Full USB-C recharge took 2.5 hours.
Verdict
At £65 the AlpenGlow is a splurge for an emergency-only light, and the lack of a crank or USB output keeps it from our top emergency spot. But as a dual-use ambient-plus-backup lantern, nothing else we tested is as nice to live with. Buy it if you'll use it nightly.
Who should buy it?
