ACR Artex C-Light Manual Activated Personal Distress Light

ACR Artex C-Light Manual is a manually activated, steady-on personal distress light with dramatically improved operating life. This waterproof light is tiny yet rugged and has a 20-lumen LED that typically operates for 30 hours continuously. The C-Light has been approved by USCG/SOLAS and is activated manually with an easy twist on/off activation, making it an ideal light for all outdoor enthusiasts.

The slim, lightweight, and versatile design fits easily in a pocket or hangs discreetly when attached to a life jacket or backpack.  The flexible lashing loops on the side of the product allow for multiple mounting options including the webbing on your backpack or straps on your life jacket.  The Velcro® strap can be secured around the lashing loops and creates countless additional mounting possibilities.  The light also comes with a clip designed to conveniently slide over your inflatable life jacket’s oral inflation tube for storing your light inside your life jacket.
