The exclusive stepless dimming function allows you to switch to the appropriate lighting in any environment, preventing you from being exposed to overly dazzling lumens. This is an exclusive feature that you won't experience with other products. 【Authentic 5000 Lumens Performance】 Unlike competitors exaggerating lumen ratings with "990,000" claims, our flashlight delivers a certified 5000 lumen output with dual-mode functionality. Users can manually switch between wide floodlight and focused spotlight settings. The spotlight mode achieves an impressive 347-foot beam distance and maintains underwater functionality up to 10 meters. 【Powerful Rechargeable System】 Equipped with a high-capacity 5000mAh battery, this flashlight fully charges via USB-C in 3 hours. A full charge provides over 15 hours of continuous use. An integrated USB output allows mobile device charging on-the-go. For added versatility, it also supports three AAA batteries using the included adapter bracket and sleeve. 【Four Lighting Modes with Smart Controls】 The intuitive interface offers quick mode switching: brief right-button presses cycle between white light and 395nm UV light, while long presses enable smooth brightness adjustment. The COB side light features four dedicated modes: 1000-lumen warm light, 500-lumen warm light, red light, and emergency SOS signaling. 【UV Detection & Multifunctional Uses】 The UV light functionality excels at revealing hidden stains on fabrics, detecting counterfeit documents, and identifying adulterated cosmetics. It also serves as a professional-grade tool for UV resin curing and outdoor activities like scorpion spotting and mineral exploration. 【Industrial-Grade Construction】 Built with aircraft-grade aluminum alloy and a sealed design, this IP45-rated flashlight resists water and impacts.
