Small enough to take with you, powerful enough to use all the time. The Trailmate is a super compact light you can keep on your keychain, but when you need a good light, its small size understates how powerful it is. At 360 lumens on turbo mode, the Trailmate is powerful enough for big jobs. The low power mode will give you light for 6 hours or switch to the green LED for 18 hours in the field.
