680 Lumens | Only 131g | IPX4 | 350M


Ferei B series bicycle lights utilize state-of-the-art high intensity LEDs and lithium-ion battery technology for maximum brightness, extended runtime and superior portability.

The Ferei B5 is an ultra-compact and ultra-lightweight CREE MCE based LED bike light that combines a hefty 680 lumens of output from a very small body.

Featuring a lightweight li-ion battery pack that provides up to 4 hours of burntime in high mode (680 lumens) and many hours more or lower modes, the B5 is ideal for commuting, recreational riding and off-roading.

The B5 comes in a kit with a sturdy helmet mount bracket, a tough anodized aluminium handlebar bracket, battery pack, quick charger and other useful bits and pieces.

Three modes of output are accessed via a single glow-in-the-dark push button and the unit is rain / moisture proof.

The B5 utilizes a premium Cree MCE quad-due LED which produces a very strong flood beam and impressive hotspot, illuminating targets at over 100 meters and lighting up the foreground on either side of the track, path or roadway.

The Ferei B5 easily competes with cheaper inferior lights rated at up to 1000 lumens due to full utilization of the Cree MCE LED and for this reason is one of the best value high powered LED bikes lights on the Australian market.
