Streamlight manufactures lights for law enforcement so you can expect that same level of quality with all of their products. The 4AA ProPolymer LED is a compact, portable light designed for daily use and emergency situations. This is a light designed with practicality as a main concern. Being 6.5 inches long, 1.63 inches in diameter, and weighing less than half a pound, you can take this light just about anywhere. Bring it camping as a reliable and useful addition to your survival accessories that won't slow you down, and watch as it runs for an incredible 155 hours of continuous use off of easily replaceable AA batteries. You won't even need to bring spare batteries with you for most expeditions. The seven ultra bright white LEDs produce 67 lumens of light, impressive considering the runtime. The 4AA ProPolymer LED can take a beating with a 1 meter impact resist rating and an IP57 water/dust resist rating. You can feel comfortable taking it into harsh work environments. The tactical tail switch offers quick and easy one handed On/Off operation, great for fire and rescue workers when time is of the essence, or just keep a few around the house in the event of a power outage or break in.
