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.
