SENSOR CONTROLLED

High-tech stereo-sensors scan the ambient light and automatically switch the SL from daytime running light to full beam. This function is especially handy at high speeds, when you may not have time to react.



LIGHT YEARS AHEAD

The heart of the SL is composed of 12 high intensity LEDs and the world's first dual Aspheric Lens System for bike lights. Their extremely robust and high quality aluminum body protects the SL from shock, dust, and water.

The SL is a special member of the Lupine family of lights. Not only is it compliant with strict e-bike light standards, but it also directs 100% of its 900 lumens directly on your path. The SL is designed like a car headlight and doesn't glare any other road users.




COMPATIBILITY

Mounting the SL A is very simple and compatible with Stem widths of 39-51mm. 



SLEEK DESIGN

The SL is incomparable. Its unique look is due not only to the distinctive "daytime running light" but above all to the development performance of our engineers. With the SL, they created the smallest and lightest lamp in its class.

   Amazing commuter light, June 17, 2018  By Robert Hollyer (Bainbridge Island, WA)
I use the SL-A head light on my daily 30-mile commute. Honestly, for myself this is the perfect light. The beam pattern is excellent. It's wide with a sharp cutoff and doesn't blind oncoming pedestrians and cyclists. The light output (lux) is excellent. The daytime running light seemed pointless but in fact it works great and is noticeably bright while not being blinding. The battery pack has a nice led state-of-charge indicator. However, the audible status is pretty quiet. You need to be indoors for the audible beep to be useful.

I bought the optional quick release mount and it works perfectly. Well engineered and easy on/off. Probably the only downside to the light is the power adapter and the power connector. They're both non-standard and the connector has a tight fit. Presumably for waterproofing. But with USB Type C experiencing wide spread adoption and at high power capabilities, it would make more sense than a non-standard power supply and connector.

Overall, this light is expensive but worth it.
   SL A4 Road Light, April 19, 2018  By Charlie Olmstwd (Hershey, PA)
The SL A4 is the perfect front head light for road cycling. I started using the SL A4 on my road bike this spring when I decided to maximize my visibility for safety reasons and desired long running batteries. So after using the light for over a month, I can say that the daytime running light LED technology is the real deal if you desire enhanced visibility to on coming traffic. Also the run time of this unit is far superior to an other front light I have ever tested. Simple operation, just two clicks to turn on and one long click to shut off. Once powered on the light automatically senses if it needs to be in daylight running mode or a full headlight....very cool!
