Schmidt Son Edelux DC 150 bicycle light

The new Edelux DC 150 headlight from Son has been specially developed for pedelec systems up to 25 km/h with V2 or V5 batteries from Neodrive.

The particularly high power consumption of 5 watts, compared to the Edelux II DC, enables an illuminance of up to 150 lux. The DC power supply is provided by the pedelec’s battery. The Edelux DC 150 must not be connected to standard hub dynamos, as these generate AC current.
A new connection system allows for quick and easy installation of the power cable: simply unscrew the aluminium cover on the rear and clip the cable directly onto the headlight. No more tedious stripping of insulation! Solder pads are provided for the use of a standard Son rear light.

Schmidt Edelux DC 150 Optics:

The Edelux uses the IQ-Tec offset reflector from Busch & Müller. Unlike conventional headlamp optics, this captures a very high proportion of the light emitted by the LED and ensures a wide and evenly illuminated path. Thanks to a sharp cut-off at the front edge, glare for oncoming cyclists is avoided. Minimal upward light scatter means low indirect self-glare in foggy conditions. The black ring around the edge of the reflector prevents direct self-glare when the headlight is positioned within your own field of vision. Precise adjustment of each LED and bench testing of every headlight ensure consistent quality. The anti-reflective front lens is scratch-resistant and allows 6 per cent more light through than a plastic lens.

Schmidt Edelux DC 150 Heat dissipation, mechanics, electrics:

The efficiency and service life of the LED depend primarily on its cooling. The LED is therefore mounted directly on a solid copper heat sink, which in turn transfers the heat to the aluminium housing. In addition, an innovative ventilation membrane provides cooling whilst offering protection against moisture. This effective cooling ensures 20 per cent more luminous flux at high speeds compared to conventional LED headlights, where the LEDs can sometimes reach temperatures in excess of 100 degrees.
