ACR C-Strobe™ H20 — Water-Activated Personal Distress Strobe Light — 33-39641

When seconds count, the ACR C-Strobe™ H20 activates automatically on water contact — no fumbling for switches in a dark, chaotic emergency. USCG and SOLAS approved, this compact personal distress strobe delivers a blinding 45-lumen white LED signal in three modes, with over 120 hours of continuous strobe runtime on two standard AA batteries. At just 136g, it’s light enough to wear on a life jacket and tough enough to handle the conditions that trigger it.

Key Features

  • Automatic water-activation — activates instantly on contact with water
  • Three signaling modes: Strobe, Steady-On, and SOS
  • 45-lumen white LED — exceptionally bright for low-light and nighttime visibility
  • 120+ hours continuous runtime in strobe mode
  • Waterproof — tested for 24 hours at 1m (3.3 ft) depth
  • Impact-resistant housing
  • Powered by 2x AA 1.5V batteries (not included)
  • USCG and SOLAS approved
  • Velcro® strap and integral lashing loops for flexible mounting
  • PFD clip for easy attachment to oral inflation tube on life jackets

Suitable For

Life jackets, offshore sailing, kayaking, fishing, camping, cycling, and any activity where emergency visibility matters.

Parts Desk Insights

Best use case: The C-Strobe H20 is the right choice for boaters who want a set-and-forget personal distress light that activates without any action required in an emergency. It’s particularly well-suited for offshore sailors, commercial mariners, and anyone wearing a life jacket in conditions where manual activation may not be possible. The USCG/SOLAS approval makes it compliant for use on vessels subject to SOLAS regulations. Batteries are not included — stock with fresh AA alkaline batteries and check expiry dates annually. Replace the unit or batteries per the manufacturer’s recommended service interval to maintain reliability.
