Edelux II are designed to be powered by hub dynamos with 6 Volt AC output. Even a t low speed you will have uniform and flickering-free light. Illumination increases up to 100 Lux at high speed.
The light beam is very wide, focusses well in the distance and distributes evenly in front of the bike. This kind of light distribution is ideal on dark roads as well as in road traffic. Standlight is very bright, and so is of more use than just to be seen. It switches off automatically after 4 minutes.
