We’re big fans of USB rechargeable lights. Think about it, you’re always conscious of keeping your phone charged. The same cord charges your flashlight. It Makes Perfect Sense. When you’re not going to be near a charging source, it uses batteries. It’s a definite EDC.
The USB-578XL USB Dual-Light Tactical Flashlight uses an LED rated at 900 lumens on high for 3 hours but can extend 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.
