Common questions
How long does it run, and how do I charge it?
2 hours 30 minutes on Low, 2 hours 15 minutes on Stealth Green and 45 minutes on High, from a full charge. A drained battery charges in about 90 to 120 minutes over USB-C.
Why does it turn off instead of changing modes?
That is Mode Memory. Once you stay in a mode for 3 seconds, the next press turns the light off, and the press after that brings it back in the same mode. To change modes, press again within 3 seconds of turning it on. Mode Memory resets when you charge it.
How do I get the ring to fit?
Shape it by hand. Pull the prongs outward to open it, squeeze them together to close it, and press the tips into your finger to tighten. For small fingers, overlap the prongs without creasing them.
Is it waterproof?
Yes. It is rated IP57: dust resistant and submersible for 30 minutes at 1 meter.
