SLAX 2023

The brightest bike lamp from Lupine

The new SL AX is safety, safety by day and safety by night. But it is also an extremely powerful lamp, perfect for fast rides and with up to 3800 lumen high beam it is currently the brightest StVZO-approved lupine for your bike.

The best of both worlds

You switch to high beam, the SL AX opens a daylight corridor far above the glare-free cut-off line and fires the 9 automotive LEDs of the main headlight to the maximum. Unique here: At the same time, the daytime running light function is switched on with significantly increased performance. Its 10 LEDs and the sophisticated Fresnel lens system increase the light output and create additional close-up illumination with which you can master fast descents and technical root passages in a playful way.

SL AX in a new light

The high beam of the predecessor was already really good, but the new one is significantly better: brighter, more even and close-up illumination that is second to none. Due to the massive light gain and the improved light image, discussions about the so-called opening angle are a thing of the past. From now on you can easily recognize every branch that flies towards you and drive through tight curves without loss of sight.

Brilliant view

For maximum range and close-up illumination, we combine the usual reflector with 10 brand new LEDs. A complex lens system of concave and Fresnel elements distributes the light evenly over the entire area of ​​your gaze.

low beam and high beam

The low beam gives you glare-free light and visibility in every situation. Away from the city you can switch to high beam with just a push of a button and fire your bike over country roads, bike paths and challenging trails.

daytime running light function

The daytime running light function of the SL AX shines particularly brightly and guarantees the full attention of all road users. The SL AX is currently the only StVZO-approved Lupine with a real daytime running light function, tested according to ECE R87.


The stereo sensor system, which can be adjusted in stages, scans your ambient light in real time and switches your SL AX from the daytime running light function to the low beam in good time. At the same time, the sensors release the high beam.

remote control

Who doesn’t know it: It’s night, the road is clear, you switch on the high beam and step on the gas. The SL AX brings this feeling to your bike. With the two buttons on the Bluetooth remote control, you can fade up and down in fractions of a second or switch through the light levels of the low beam.

For a little more power

The SL AX not only scans your ambient light but also your movement. After 5 minutes of standstill, the SL AX deactivates your remote control to save power and switches it on again immediately if you move.

Waterproof and impact resistant

Especially with lights mounted on the handlebars, it can happen that your bike with the light is standing in the rain or it gets hit when you fall. Therefore, the SL AX is waterproof and impact-resistant according to IP68.

Even more convenient thanks to the app

You can now also control your SL AX via the new APP using your smartphone or smartwatch. In particular, the settings for the light levels are even easier.

Milled with precision

The SL AX is not only smaller than any comparable lamp, but also uses every millimeter inside the housing. The housing is milled from a piece of aluminum with minimal tolerances.

Simply assembled

A CNC-milled aluminum quick release allows for easy mounting of the lamp on the handlebars.

Built to last

The SL AX is not a disposable product: As is typical for Lupine, permanent adhesive solutions are deliberately avoided during the development phase. Our lamps are designed to be easily disassembled, repaired and reassembled.

    Love the auto on/off setting. Never have to touch it when you ride through the dark spots. Big field of view is nice too!
