Nightstick Metal Dual-Light Rechargeable Flashlight Popular

The Nightstick Metal Dual-Light Rechargeable Flashlight uses an LED rated at 900 lumens on high for 3 hours but can be extended up to 22 hours in low mode (150 lumens). At only 5.8 inches long and weighing only 6.9 oz, this metal tactical flashlight is multi-functional, cycling between high, medium, and low modes with an optional strobe when you press twice in succession on the upper tail-cap switch.
The secondary switch located below provides 250 lumens for 3.5 hours. Press both buttons independently to go into exclusive Dual-Light mode at 500 lumens for 2.5 hours which is ideal to light up your downward-facing proximity and at a distance for maximum illumination. The USB-578XL is rated IP-X7 waterproof and features a discretely sleeved collar that opens for direct USB charging. The built-in charging indicator turns from red to green when fully charged. Included is a 2 foot USB charging cable, li-ion rechargeable battery, and CR123 battery carrier (batteries not included) for added convenience.
