A light that easily fits in the palm of your hand, the Black Diamond Iota is the daily driver for quick-hit morning trail runs, post-work ridge scrambles and urban adventuring. Emitting 150 lumens on the max setting with an average three-hour burntime, the lithium ion rechargeable battery eliminates waste, and an IPX4 rating protects against splashed water from any angle. Powertap Technology allows for fast, easy brightness adjustments, and a lockout feature safe guards your battery life.
