Product Overview

The SM-3 is a high intensity LED strobe which provides 360° visibility for approximately 2 miles. This compact yet durable marker light facilitates rescue by automatically activating and beginning to strobe when in the water, working for over 40 hours at 30oC (86oF) or over 24 hours at -1oC (30oF). Perfect for commercial marine, petro-marine, cruisers, and any other application needing a reliable Crew Overboard Marker (COB) light, the SM-3 floats upright in all conditions, ensuring it will keep shining when you need it the most.

With a minimum light intensity of 3 candelas throughout its entire operating life, this high intensity LED strobe clearly marks a crew-overboard site with each brilliant flash. It automatically rights itself and activates when in the water, ensuring that activation is never an issue that a crew member in distress needs to worry about. The SM-3 operates on 2 AA Lithium batteries and the batteries are user replaceable, allowing the potential for a longer product life than the many disposable lifebuoy lights on the market.
