Serfas USM-350 E-Lume 350 Lumens Headlight

Description

New for 2021. Serfas E-Lume Series Headlights feature 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, so they 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 temperatures for optimal battery performance and consistent light output.

Light output of the E-Lume 350 is sent through a single optical lens creating a powerful beam with strong front illumination and excellent side visibility.
