The TASER Strikelight is the perfect balance and combination of safety and security. It combines an 80-lumen flashlight with the stopping power of a stun gun. To use these features there are two separate activation buttons. Since it is meant for self-defense, the Strikelight has been made of a lightweight, but durable anodized finished aluminum with a high-strength polymer front lens holder and an anti-roll design, so it can last and is easy to use. This stun flashlight is powered by only one rechargeable 18650, 2500 mAh lithium polymer battery, which is included. The battery takes 8 hours to fully charge once depleted with the included AC wall charger. When fully charged, the battery provides 5 hours of continuous light or 100 5-second stun discharges. Additionally, there is a wrist strap provided, so you can carry the TASER Strikelight with ease.Product features: Slide on/off switch forward to turn on the LED and put electrodes in standby Dual switches prevent accidental discharges Visible electric arcs make a loud crackle to scare off attackers High-strength polymer front lens holder Anti-roll design Rechargeable battery takes 8 hours to fully charge Weight: 0.6 lbs.
