The Brighter, Better Keyring Torch

There are dozens of keyring torches on the market these days. This, from American brand Coast, is one of the best. Despite being only 6cm in length, the G4 punches above its weight with an 18 lumen pure white beam, aircraft-grade aluminium barrel, and build quality that is just as robust as its larger brothers.

Uses 4xAG5 batteries (included).
