SON Ladelux Headlight, High/Low Beam, Charger

Price range: $465.00 through $495.00

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.

The SON Ladelux Switch for the light and high beam also includes the charging port. It is sold separately, so you can choose the length of the wire (which depends on where you mount your headlight).

The standing attachment is compatible with our Rene Herse racks and light mounts as well as other mounts.

Requires mount and SON Ladelux Switch (available separately)

Available with:

  • 120 cm wire; separate flat spade connectors
  • 120 cm wire; coaxial connector installed; includes Coaxial Hub Adapter

Pro Tips:

  • The included SON spade plugs 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 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.)
  • Standing attachment (do not mount upside-down)
  • Mount not included (available separately)
