Product Overview: UltraFire® LW20X PRO Flashlight

The UltraFire® LW20X PRO is a high-performance, long-range tactical flashlight engineered to deliver extreme reliability in complex and changeable outdoor environments. Built around a specialized KW CSLNM1.TG LED emitter, this flashlight is designed for maximum operability with a classic tactical tail switch, ensuring users can deploy a piercing beam with confidence during hunting, search and rescue, or demanding outdoor work conditions.

Key Build and Performance Features

Precision Optics & Output: Powered by a high-efficiency KW CSLNM1.TG LED emitter, the LW20X PRO delivers a max output of 370 lumens. It boasts an incredible peak beam intensity of 100,800 candela (cd), throwing a focused beam an impressive 2,067 feet (630 meters) through the dark.

Aviation-Grade Construction: The flashlight body is machined from robust AL6061-T6 aviation aluminum and finished with a military-grade, three-level hard anodizing treatment to resist heavy wear and tear.

Weather & Impact Readiness: Built to handle the elements, it features an IPX6 water resistance rating to withstand heavy rain and splashing, alongside a tested impact resistance of 3.3 feet (1 meter) to survive accidental drops.

Optimized Everyday Carry (EDC) Profile: Engineered for comfortable handling and transport, it features highly portable dimensions of 6.46 x 1.81 x 1.07 inches and a balanced weight of just 7.47 oz (211.7 g).

Power Management and Charging

Reliable Runtime: The highly efficient driver provides up to 2.5 hours (150 minutes) of continuous runtime on a single charge.

Rechargeable Power Source: The system is powered by a high-capacity 18650 rechargeable lithium-ion battery.

Type-C Integration: It utilizes modern Type-C charging technology directly on the device, complete with an integrated charging indication function.

Smart Battery Indicator: A dedicated battery indicator light is conveniently located on the neck of the flashlight. By pressing the tail switch while the flashlight is powered off, the indicator illuminates for two seconds, utilizing different colors to accurately display the remaining battery power.

Intelligent Safety Systems

Active Temperature Control: To ensure longevity and user comfort, the LW20X PRO includes an intelligent temperature control system. If the built-in chip detects high temperatures during prolonged operation, it will gradually decrease the output to prevent rapid overheating. Once temperatures drop to a safe level, it automatically resumes full-power operation.

Low Voltage Warning System: To prevent battery degradation, the flashlight actively monitors power levels. When power is critically low, a red indicator light will flash, and the main flashlight beam will pulse three times every minute to remind the user to recharge immediately.

Eye Safety Warning: Because the high-candela brightness of the emitter is extremely concentrated, users are strictly warned never to look directly at the light source to avoid eye damage.
