The big little light on your keyring! The K4R is a keyring lamp that raises performance, technology and design up to a new level.
Not only does this lamp fit on your keyring and look great in a sleek aluminium case, but it also provides up to 120 lumens of light. All this from something this small is a true technological breakthrough.
Charging your K4R is as easy as plugging in the integrated USB into a charging port, no need for a charging cable.
