Description

The Fenix BTR20 is a high power rechargeable bike light with both a handlebar and helmet mounting bracket – perfect for all cycling, including commuting, cross country and off road.

The mounting bracket allows left to right adjustment of the beam direction (it can rotate 360 degrees on its pivot) and the bracket uses rubber O-ring style straps to attach it to handlebars with a of diameter 20-35 mm. The O ring style handlebar attaching straps enable a simple quick release system for you to remove the lamp when the bike is left unattended.

The bike light runs off the included sealed rechargeable BA2B battery pack – the charging cable has adapters for both 3 pin UK & 2 pin Continental style wall sockets. The BA2B battery pack is equivalent to 2 x 18650 batteries and has a charging and power level indicator. The BA2B battery pack has protection against over-discharging, over-charging and over-heating.

The Fenix BTR20 has an aerodynamic design and cooling vents for heat dissipation. The bike light has a low power warning.

The digital control circuitry maintains a constant brightness for as long as possible.

The bike light comes with an integral remote pressure switch that can be mounted on the handle bars to give instant access to the Turbo mode (whether the light is already on or not).

The Fenix BTR20 features a Cree XM-L T6 Neutral White LED with a maximum output of 800 lumens. The neutral white tint provides excellent colour rendition and improved penetration of rain and fog. The wide beam aspherical reflector delivers a innovative dual distance illumination, covering a wide area both close in and at long range.

The single switch controls on/off and selection of brightness level.

Brightness Levels based on the included BA2B battery pack:
Turbo: 800 lumens – 2 hrs runtime
High: 400 lumens – 4 hrs 40 mins runtime
Mid: 200 lumens – 10 hrs runtime
Low: 80 lumens – 23 hrs runtime
Flashing Mode: 200 Lumens

Maximum beam distance 167 meters and weatherproof to IPX-6.

Includes: Fenix BA2B battery pack, o-ring mounting straps (2 for handlebars 20-24mm, 2 for handlebars 24-30mm, 2 for handlebars 30-35mm), extension cable, charger cable with both UK 3 pin & continental 2 pin adapters, helmet mounting strap.
