Topeak Headlux 100 USB Front Headlight Review - feat. Dual LED + 40 hr Runtime + Daytime Visible

To be safe while cycling it’s important to not only ride defensively but to also make sure other people see you. Compact and bright daytime visible lights are one essential way to ensure that. Today we’ll be looking at Topeak’s answer to daytime visibility which is the new Headlux 100 USB. At only $27.95 the Headlux 100 USB is one of the smallest front lights in Topeak’s Headlux lineup. The two 0.5W white LEDs can put out up to 100 lumen of output and are powered by an integrated 500mh Lithium Ion battery. Topeak has also incorporated the USB dongle directly on the rear of the Headlux 100 USB which means the light has a cable free design and can be directly plugged into USB Type-A ports for charging. With its compact size and simple rubber strap mount design, the Headlux 100 USB can also be mounted on aero bars, round bars, helmets or under center mounts.

With the small form factor of the Topeak Headlux 100 USB it’s not surprising that Topeak has chosen simple rubber strap mounts. It’s the same design as the Topeak Headlux 450 USB with two integrated plastic posts on the left and right side of the housing. Topeak refers to it as bi-directional tool free design as the two included straps allow the Headlux 100 USB to be mounted perpendicular to handlebars or parallel to out-front mounts. The handlebar mounting is a bit confusing as you have to wrap the strap around the mounts twice. It’s not nearly as convenient as Garmin style mounts found on lights such as the Magicshine Allty 400 but makes it compatible with a variety of handlebar shapes. Topeak also includes an extra rubber pad that fits over the curved rubber pad that helps angle the light downward when mounted under out-front mounts.

As a “be-seen” headlight it’s not surprising that the Topeak Headlux 100 USB is a small light. It’s not much larger than a USB thumbdrive which means it can be easily mounted in a variety of locations. Thanks to the plastic body and lens the Headlux 100 only weighs 52 grams which means you’ll hardly notice it if you mount the light on your helmet. The light design is very similar to the Topeak Headlux 450 USB with a two LED setup, rounded rectangle profile and symmetric body. The main difference between the Headlux 100 USB and the 450 USB is the plastic construction, smaller size and lower output. Branding is limited to Topeak and Headlux 450 printed on the sides of the housing.
