LED Lenser M3R
This rechargeable product is the latest in a line of great small torches from LED Lenser. At under 10cm long, it can be kept on a key ring or slipped into a pocket with the clip, but it still packs a punch. The bright LED can be adjusted with one hand, giving a long-distance beam or a wide spread for under the bonnet. It comes with a USB lead, but you’ll need adaptors for mains and in-car charging.
Light test: 3 hours
