Overview
Taking dynamo lighting to the next level, the Ladelux brims with innovative features. In addition to the layered low beam—similar to the Edelux II, but brighter—the Ladelux features a high beam that doesn’t just reach further, but also illuminates curving roads better. There is a power take-off to charge electronics. To avoid damaging the connected electronics with multiple on/off cycles, a built-in battery buffers the charging. The battery also powers the lights: As long as the battery is charged, you can run both low and high beam at all speeds—even when stopped.
A strong all-aluminum housing and scratch-resistant sapphire glass increase durability and reliability. Excellent cooling and careful location of the LED in the reflector ensure maximum light under all conditions. The electronics are specially designed to optimize the power output of the generator hub: With up to 14 watts, it allows charging even at moderate and low speeds.
Features
Standing attachment (do not mount upside-down)
Mount not included (available separately)
Requires SON Ladelux Switch (available separately)
Standlight (turns off automatically after 4 minutes)
120 cm wire; separate flat spade and coaxial connectors
120 cm wire; coaxial connector installed; includes Coaxial Hub Adapter
The SON spade connectors are field-serviceable, but they require careful installation so they are secure enough that they don’t come off if the wheel is removed accidentally without unplugging the connectors. The co-axial connector has been 100% reliable, and it pulls out of the hub even if you forget to unplug it before removing the wheel.
The Ladelux is also available with a SON Coaxial Connector already installed, ready to plug into your hub.
Or install your own coaxial connectors and customize the length of your wire. (In that case, choose the light with separate flat connectors and add a SON Coaxial Connector (available separately). Here’s a  how-to video showing the installation of SON coaxial connectors. (Make sure to use enough solder.)
Specs
Low beam: 150 lux (always available, green LED on)
High beam: 200 lux (when battery charge is sufficient; blue LED on; flashes 3x if not available)
Charging (when battery charge is sufficient; LED pulsates)
Built-in buffer battery (1200 mAh)
Battery does not charge/discharge in extreme temperatures for safety (<-4°F/-20°C or >140°F/60°C), high beam and charging may not be available then
Taillight connector (if not used, cover and seal with heat-shrink tubing)
Taillight must have 2-wire connection (do not use frame as return path for taillight current)
