The XLC LED dynamo headlight CL-D01 features one white LED dynamo beamer with a luminosity of 35 lux. It’s easy to mount to the front of your bike with its stainless steel mounting, and it comes with a reflector and cable to make life as easy and safe as possible. Dynamo lights are a great investment, especially for anyone who would rather not deal with batteries that need replacing or recharging over time. A dynamo converts the energy created by forwarding motion into electrical energy that supplies the lights on your bike, providing always-on illumination. This makes them ideal for commuting or city riding and for long-distance trekking where power is in short supply.
