With the choice of a bright 660 lumens on high and an energy-saving 225 lumens on low, in focused spot or wide flood beams, the Coast HP7L Dual Power LED Flashlight delivers the light you need in just about any situation. The HP7L's versatility extends to its power supply—use the four included AAA alkaline batteries, or go rechargeable with ZITHION-X™ cells. Runtime ranges from 2.5 hours on high to 12.5 hours on low. The Coast Pure Beam Focusing system is accessed by sliding the head forward and back with effortless one-handed operation. This sturdy, 5.5", 4.1-ounce light is rated IP54 dustproof and splashproof, so it's safe to use in challenging conditions and inclement weather. Another challenge the HP7L overcomes: it won't roll off a car hood or a sloping surface, thanks to its anti-roll tail cap.
