The flexible lashing loops on the side of the product allow for multiple mounting options including the webbing of your backpack or the straps on your life jacket. The C-Strobe H2O also comes with a clip designed to conveniently slide over your inflatable life jacket's oral inflation tube so you can store the light inside your life jacket. With 3 modes of operation (strobe, steady-on, SOS), the C-Strobe H2O boasts a 45 lumen LED that typically operates for 120 hours continuously when in strobe mode.

The light can easily be activated with a simple push of the on/off button or when in the armed position. It can also be activated automatically when immersed in water, making this strobe an ideal light for all outdoor enthusiasts. Plus, the C-Strobe is USCG/SOLAS approved, and features an impact-resistant case, making it a reliable, multi-purpose light whenever efficient distress lighting is needed.
