When it comes to lights the more lumens you’re packing the better. Think of lumens like options, the option to see further and be seen. As it gets darker or you’re traveling faster you want more lumens. A weak light source is all but useless.
In days gone by lighting technology was limited by run time and battery pack size. Get a large enough light and a decent run time and you were hauling some 5lb extra weight around in the form of a nice battery pack. Today CygoLiteExpilion 400 LED Light offers up to 400 lumens in a 130 gram palm sized light. Mount it to your handle bar or helmet.
The CygoLite Expilion 400 LED Light uses a standard Li-lon internal battery to power the Cree LEDs. On high you get a full 400 lumens of bright focused light with enough peripheral wash to see objects to the side. Visibility is wonderful both for you and oncoming traffic.
The Expilion 400 LED USB charges via USB in 5 hours by either plugging it into your computer or using the provided wall mount.
Run times: high 3 hours, med 6 hours, low 13.5 hours, boost 2 hours, and flash 24 hours.
Includes light, battery, wall charger, helmet mount, and USB cable. 130grams.
