There's brightness and then there's how'd-that-car-get-on-the-trail brightness. And the CatEye Sumo 3 Headlight certainly leans towards the latter.

To start, CatEye incorporated three LED bulbs that exude up to 5500 candlepower. If you're used to reading output levels in terms of lumens, let us explain how this varies from candlepower. While lumens is the calculated measure of how much light a bulb produces in all directions, candlepower is the measure of light intensity at the center of a spotlight beam in one direction. How does this translate? Messily, but our contacts at CatEye assure us that the Sumo 3 has a 1600 lumen output. So, whether you're illuminating the road or trail ahead of you, this light will provide more light than a car's high-beams. We're being completely serious, the average headlight's high beams illuminate around 1200 lumens.

For durability, the Sumo 3's LEDs rest in a sturdy all aluminum housing. Additionally, the light has also been designed to be water-resistant. So, you can depend on the Sumo 3 as the conditions become less than ideal. For attachment, CatEye incorporated its tried-and-true FlexTight bracket that simply attaches to nearly any style of handlebar.

In terms of modes, the Sumo 3 has four. For a maximum output, and the shortest battery life, there's Dynamic. The next three, Normal, All-night, and Flashing, move from solid to flashing. All in all, the Sumo 3's rechargeable lithium-ion battery has a life range from 1 to 35 hours depending on your mode selection. However, when your ride is done, CatEye predicts that a full recharge of the battery can be performed in around five hours and an 80% recharge will take around 2.5 hours.

The CatEye Sumo 3 Headlight is available in the color Black and in one size. Each light comes equipped with CatEye's FlexTight mounting bracket and a charger.
