The most powerful torch in the Coast professional XP series, the XP18R Rechargeable Dual Power LED Flashlight is suited to everything from home use to law enforcement, search and rescue, or the industrial sector. This 10.3", 19.4-ounce light offers four brightness levels, topping out at a 3650-lumen turbo setting, and runtime ranging from 6.5 hours on high to more than two days on the 65-lumen low power setting. Coast's Slide Focus mechanism makes it easy to alternate between a wide, smooth flood beam and a sharply focused, long-throw spot, and you can lock in the beam angle you want with a simple counterclockwise twist of the light head. Power and brightness levels are controlled by a push-button switch on the tail, which also serves as a real-time battery status indicator. Slide back the tail end of the light to reveal Coast's Pro-Tek direct-connect port to re-power the Zithion-X battery pack. The light can also run on six AA batteries if recharging isn't an option. This dust-tight, water-resistant light is made of aluminum and stainless steel, and its grenade-like handle texture provides a secure and comfortable grip.
