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
The rubber-armoured body shrugged off everything we threw at it, including full submersion (it's IPX7-rated) and repeated drops onto concrete. A removable globe diffuser, a sturdy D-ring, and a magnetic base make it genuinely versatile. It runs on three AA cells, which is a deliberate strength for long-term storage.
Performance
Output tops out at 340 lumens — modest, but more than enough for room lighting during an outage. The standout is endurance: 200 hours on the low setting, by far the longest in our test. A dedicated red-light mode preserves night vision, useful when checking on a sleeping household.
Verdict
Because quality AA alkalines hold charge for 5–10 years, the Siege AA is the lantern most likely to actually work when an emergency arrives — no flat lithium battery to discover at the worst moment. At £35 it's our pick for set-and-forget storage.
