The LED Lenser SEO B3 is a versatile lamp that functions as a bike light with the included universal mount, that could also be attached to tent poles for use while camping. Incorporating a LED Lenser SEO headband (sold separately) transforms this lamp into a a handy, lightweight head torch.

Whatever your application may be, the SEO B3 offers a maximum output of 100 lumens that can be dimmed between 100-15% using LED Lenser's Smart Light Technology. This is achieved simply by pressing the button once to turn the light on and then holding the button down to cycle from 100% down to 15%, and releasing the button when you reach your desired output. Low power can be accessed by pushing the power button twice to emit 15 lumens and three pushes of the button will activate strobe mode.

A red LED is also available to preserve night vision and had constant on or flashing mode to attract attention. Holding down the power button from off for three seconds will enter red light mode. Another useful feature is the Advanced Focus System. A twist of the bezel allows the beam to be focused from spot to flood with ease.

The SEO B3 comes supplied with three AAA alkaline batteries, however this head lamp can also use the SEO replacement battery (sold separately) making it cost effective and increasing run times. For extra safety, the LED Lenser B2R red bike light (9002) makes a perfect companion for the SEO B3 as a rear bike light.
