The Ledlenser K6R is a very small aluminium keyring torch with a built-in rechargeable lithium-ion battery. Instead of a separate charging cable it has a fold-out USB-A connector, so you simply plug the light into a laptop, wall charger or power bank to recharge it. Despite its size of roughly 62 mm, it gives up to 400 lumens in boost mode with a beam distance of about 80 m, and it has several light modes for everyday tasks such as finding keys at the front door, reading a meter box or walking to the car at night. The housing is made of aircraft-grade aluminium alloy and is splash resistant (IPX2). This version has a gold finish. Ledlenser has discontinued the K6R, so this is end-of-line stock.
