The BT20 LED Bike Light from Fenix is a high performance bicycle light with four brightness levels and a maximum output of 750 lumens. It employs a Dual Distance Beam System with an aspherical reflector that enables floodlight illumination, close-in visibility and long-range illumination so all areas, immediately in front of your bike to 512' down the road, are illuminated. Furthermore, the upward beam of the BT20 is aimed toward the ground and will not shine in the eyes of pedestrians. The BT20 utilizes the Cree XM-L (T6) neutral white LED which improves safety as it allows the rider to better identify the color of objects which might cause road hazards. The BT20 runs on two 18650 or four CR123A batteries, and can also run on four AA batteries with the optional BA4A battery case. At full power, the maximum run time is 1.5 hours and at low power the maximum runtime is 19.5 hours. A 300-lumen flashing mode is also available.  

Supplied with three flexible yet strong O-rings, the BT20 will easily attach to any set of handlebars with a diameter between 20-35mm. The direction of the headlamp is easily adjustable and an included helmet mount allows use on bike helmets. Built from die-cast aluminum alloy and performance plastic components, the BT20 is aerodynamic, water-resistant at the IPX-6 standard and impact resistant up to 3.3' (1m). Brightness levels can be adjusted with a simple press of the top button which illuminates green, then red and then flashes red as battery capacity diminishes.
