Cateye's Volt Series lights offer exceptional value, flexibility, and technology for riders of all types. The Volt 400 is a perfect emergency light for road cyclists, and ideal for commuters who don't want a bulky light system, and might choose a different bike every day. The 400 Lumen single lamp LED light throws a distinct, wide beam that effectively ranges out beyond 30 meters and can be seen much further away. You have handlebar and helmet mount options and fast USB charging. Cateye's proven electronics are super-reliable and efficiently manage power. This compact, sleek, 120 gram lamp can run at the full 400 Lumens for 3 hours and you get multi-mode capability along with a flash option.

The Volt 400 offers 180 degree visiblity with side lens cut-outs. The power/mode button is simple and easy to use, and features a low battery indicator light when you get to about 30% of run time remaining. Ease of use continues with Cateye's standard mounting system, which uses a secure side in mechanism and locking edge to hold the light in place via either the Flex-Tight bar mount, or the included helmet mount. With the Flex-Tight, you can purchase extra mounts for multiple bikes, or simply unscrew the ratcheting strap system and remount elsewhere. The low profile lamp sits cleanly and close to the helmet when using the strap-style helmet mount. Options, options, options.

Lighting modes and run times are excellent for such a small, well powered light. Three hours at the full 400 Lumens is generally more than enough for morning and evening commutes, and the standard recharge time on the Li-Ion battery via the micro-USB cable is about 6 hours with a minimum USB 2.0 port. You also get Middle mode (100 Lumens), which is rated for eight hours of use, so managing your light is straightforward. The other most commonly used mode is the Flash, which pumps out a 50 Lumen Flash for 60 hours. The light even features a mode memory feature, so it returns to the last used mode when powered up. Please keep in mind that Cateye offers a feature that few other companies can touch. The battery is actually a removable cartridge, and you can purchase additional batteries, as well as a charging dock for the battery that expedites charging and cuts the charge time in half.

There are many great lights on the market with this 400 Lumen output, and many at great prices, but the Volt 300 is a customer favorite. In the rare instance you have any issues with any Cateye product, Cateye America delivers excellent customer support and supplies small parts. If you need a reliable, weather resistant light for your daily commute, morning or dusk rides, look no further.
