Olight S65 Baton Flashlights take the intuitive design of the S35 Baton and expands it, strengthens it, and supersizes it in a big way. While the S35 uses three AA batteries, this Olight flashlight doubles that. Six AA batteries slip easily into the integrated battery compartment of the S65 Baton, capable of pumping out up to 700 lumens at its highest setting, almost twice that found on the S35. This flashlight doesn't run for five minutes and peter out, either; on its lowest setting, the S65 can last for 360 hours, while it can operate at maximum power for about an hour and a half. The O-Light S-65 Baton Flash Light features a total of four different lighting modes, five if you count the momentary on function. An intuitive operating system allows you to cycle between the three constant current modes - High, Medium, and Low - by holding down the power switch, activate the strobe feature by double-clicking it, or briefly turn on the LED flashlight by lightly depressing the switch. O-Light has built these flashlights with durability in mind; they've earned an IPX-8 waterproof rating, are built from Type III anodized aluminum, and are equipped with an anti-reflex coated, nearly indestructible lens. They also come with several useful flashlight accessories, including a white diffuser, a flashlight holster, and a keyring attachment. For a medium-scale flashlight with large-scale power, pick up the O Light S65 Large Baton Lamp.
