Color: Black Included Components: Battery Product Dimensions: 20D x 40W x 30H mm Battery Type: Lithium Ion Number of Batteries: 3 Lithium Ion batteries (included) Water Resistance Level: Waterproof 【Industry's First Headlamp with P190 & Amazingly Bright】This ultra-bright LED headlamp uses the P190 made by the world-leading LED manufacturer, U.S.A. The brightness of the projected luminous flux completely surpasses that of the same type of headlamps, with an actual illumination brightness reaching 800,000 lumens and supporting a maximum irradiation distance of 2000m. This high-brightness headlamp is about 10 times brighter than a normal P50 headlamp and about 20 times brighter than a T6 light. It's 18 times brighter than an L2. This super-bright LED is made by the U.S. CREE, which is used by the U.S. military and many police and fire departments around the world! It's absolutely not available in domestic electronics retailers! The LED chip has an ultra-long lifespan of about 100,000 hours!! It lasts relatively long and has the characteristic of low running costs. Once purchased, it can be used for a long period of time with only the electricity cost for charging. 【Rapid USB Rechargeable & Remaining Power Display & Continuous Lighting for Up to 30 Hours】This strongest LED headlamp is equipped with an eco mode, allowing for approximately 30 hours of continuous use, which is useful in disasters and for long periods of outdoor use. The total lifespan is about 100,000 hours, and it can be used repeatedly by charging, eliminating the need to replace batteries, making it economical. This battery, unlike inferior and low-capacity batteries, has built-in reverse connection protection, overvoltage protection, and short-circuit protection. 【5 Mode Dimming & Automatic Shut-off with 3-Second Long Press & Zoom Function for Near and Far】This bright LED headlamp has 5 lighting modes. Simply pressing the switch switches between high brightness → medium brightness → low brightness → flashing → SOS → off, easily adapting to various dark environments. The upgraded switch design avoids the inconvenience of conventional power-off, so you can turn it off by pressing and holding for 3 seconds in any mode, allowing for comfortable use without stress. With the beam zoom function, extend the head of the headlamp to switch between wide light and focus headlamp. Zoom out to gather light and increase brightness, and zoom in to expand the illuminated area. The improvement in zoom performance allows for irradiation further and wider.
