Black Crater’s cord lock looks gimmicky but quickly becomes a must-have. It’s a tiny three function white Led aimed at anyone enjoying the great outdoors. Powered by two CR1220 batteries, it attaches to clothing, sleeping bags, tents or anything with a cord. It's a great safety backup and powerful enough for map reading or fixing flats. Just a pity it isn't a bit better put together.
Weighing a mere 8g and measuring 35mm x 24mm x 22mm it threads on to anything with a drawstring from casual hoodies through to training jackets and tents. In a pinch you can mount it to your handlebars using a zip tie. Illumination is surprisingly good - enough to get home in an emergency should your main lighting system fail.
Quoted run-times (50 hrs flashing, 20 hours low beam, 12 hrs high beam) won’t set anyone’s inserts ablaze but appear accurate and given that it’s intended as a contingency tool, direct comparison with bike-specific LED lamps is unfair.
It's supposed to be weather resistant but the battery cover definitely benefits from a slither of Vaseline. Ours failed after being dropped into shallow water but made a full recovery when dismantled and allowed to dry.
The Cord Lock light is a very clever idea that could prove invaluable for nocturnal riding but build quality and weather sealing need improvement.
