## Questions & Answers

**Q: Great hand-held flashlight, in addition to being a great bike light--but I would love to find a way to attach a lanyard.  Any thoughts on that?**
A: No real loop to run a lanyard cord through. However, the surface has square treads on it. So, a zip tie would stay in place securely. I would use a zip tie to hold the lanyard cable and the light together.

**Q: The battery is supposed to last 7 hours on normal mode, but how long does it last on 860 lumens?**
A: I haven't completely drained mine yet but I have used it at least 4 hours on 860 lumens

**Q: Defective battery or light? I followed instructions & the battery anode faces forward & rear cap securely tightened. Charged 12hr but no light!**
A: When charging this unit, a blue light should appear around the on/off button all during the charging, and it shuts off when the battery is fully charged. If this is not happening, check the way you are charging.

**Q: Can you mount it on your helmet?**
A: Not with he hardware it comes with--unless I missed something. You could probably saw off the bracket and screw it into your helmet with a backing plate. Seems like too much trouble.
