Supernova V521s

The SUPERNOVA V521s HBM, with its side mount, is designed for handlebar mounting. The wide beam pattern of the TERRAFLUX 4 lens illuminates the path ahead superbly. Operating at 5–21 volts, the headlight can be fitted to almost all e-bike drives.

Please note: The side HBM mount (ø 31.8 mm) for this headlight is included in the scope of delivery. The HBM lamp housing is only compatible with this supplied mount and cannot be fitted to the Universal HBM.

Terralux 4 lens

The TERRAFLUX lens was a milestone in Supernova’s development and is now in its 4th generation. Hardly any other lens of this size produces such bright and even illumination. Thanks to sophisticated light guidance, the TERRAFLUX lens directs 90 per cent of the light to where it is most urgently needed: onto the road. There, it creates a wide and even carpet of light that extends from the front wheel far into the horizon. The permanent daytime running light integrated into the lens ensures excellent visibility of the rider in traffic during the day. At night, this light is used to provide superb ambient illumination, making road signs and low-hanging branches clearly visible.

Aluminium housing

For our housings, we use aerospace-grade aluminium because it is not only extremely sturdy but also has excellent thermal conductivity. The better the cooling, the brighter the LED. Cooling fins on the housings increase the surface area, allowing heat to be dissipated more effectively. Furthermore, the housings are salt-water-resistant anodised and withstand the harshest conditions. Extreme tests carried out in all seasons and climate zones by ultracycling athletes using Supernova lighting demonstrate its outstanding reliability and durability.

LED Cooling

Maximum performance with the best possible efficiency is our credo. The enormous brightness levels of our headlight systems can only be achieved through sophisticated cooling of the high-performance LEDs. Because: the better an LED is cooled, the brighter it shines. Good cooling also significantly extends the service life. Careful material selection and sophisticated design are among the most important prerequisites for ideal heat dissipation. Completely uninterrupted heat dissipation can, for example, only be achieved through a housing seamlessly manufactured from a single piece of aluminium. In extreme situations, an integrated heat sensor also ensures the spotlight always remains within the optimum temperature range. Through computationally intensive computer simulations, our engineers identify the most suitable method for dissipating heat from the LEDs at an early stage.
