Compact and handy pen light.

The i4 is a slim, compact penlight that you can carry in your pocket or clip on to your notepad and have a dependable light source at your fingertips. With two micro-cells it delivers light up to 262 feet and a luminous flux of up to 120 lumens. Like all penlights in the Ledlenser i-Series, it is fitted with the our patented Advanced Focus System that allows you to transition light from a broad flood beam to a sharply focused long-distance beam. If used in the lowest light setting, the i4 will provide you with a source of light for up to 20 hours.

wonderfully useful and versitile

This new i4 is a significant upgrade, offering a really bright 4-hour 120 lumen mode or a modest 20 hour 10 lumen mode when needed. It is slim and easily fits in the pocket and works particularly well when held in the mouth for hands free use!
