Serfas USM-1750 E-Lume 1750 Bike Headlight

The All New 2021 Serfas® USM-1750 E-Lume 1750 Headlight

New for 2021 the Serfas USM-1750 E-Lume 1750 Headlight features a redesigned extruded aluminum housing, new optical lens with excellent side visibility, and improved battery capacity and LED performance.

Serfas made not only increased performance a priority but also improved rider visibility. Serfas designed an all new optical lens and housing with front corner cutouts to allow drastically more light be visible when viewed from either side – and this all without any reduction in quality of forward illumination or beam pattern.

Constructed of aluminum the E-Lume housing is strong and lightweight as well as an efficient thermal conductor which effectively reduces heat buildup thus helping maintain cooler temperatures for optimal battery performance and consistent light output.

Light output of the Serfas E-Lume 1750 is sent through dual optical lenses creating a broad powerful beam with strong front illumination and excellent side visibility.
