The Nitecore TIP is every bit as powerful as its predecessor with dual modes and a detachable clip. The Daily and Constant On modes give users more control over their light based on their intended frequency of use. In Daily mode, the Tip will automatically shut off after 30 seconds of use meaning youll never have to worry about leaving your flashlight on again. For those who desire more control, Constant On mode will stay on until turned off. Weighing under an ounce, the TIP uses a CREE XP-G2 S3 LED to emit a max of 360 lumens. Instead of an electronic lockout mode, the Tip 2017 has a detachable multi-purpose clip which doubles as a switch protector, preventing accidental button pushing. Rechargeable through the built-in micro USB port, the internal li-ion battery and circuit design give this keychain flashlight up to 46 hours of run-time and holds up to a year in stand-by. A few minutes with the Tip 2017 and its clear this flashlight is a worthy addition or upgrade to any keychain.
