A friend bought this one: Total package, light, mount, battery, and charger, free shipping.

Mine runs bright for 3 hours then I change the battery. ( I have three of the 18650 lights)

I have been using the batteries for 3 months no problems

Super Bright Road light with adjustable beam.

Super Bright Strobe for Daytime Safety.

I saw it the other night from 1/2 mile away.
