NOTICE: Stated data has been measured in accordance with the international flashlight testing standards ANSI/NEMA FL1 using an integrated and fully charged 3.7V 500mAh rechargeable Li-ion battery under laboratory conditions. End-user results may vary due to individual usage habits and environmental conditions.* The runtime for TURBO mode is the testing result before starting temperature regulation.

Operating Instructions

ModesTIP /TIP CRI /TIP SS/TIP Cu comes with 2 modes users can switch between them depending on user preferences.

Mode switching: Hold down both switches until the LED flashes to switch between modes.A single flash indicates “Daily mode” and a double flash indicates “Constant-on mode”.
