ACR launches crew-overboard LED strobe


ACR Electronics’ new SM-3 Automatic Buoy Marker Light is a high-intensity LED strobe that provides brighter light in all directions for clear marking of a man-overboard site, according to a company press release.

When thrown in the water, the new ACR light automatically activates and rights itself to float upright in all conditions, strobing for over 24 hours at a temperature of -1 C (30 F) on two replaceable AA L91 Lithium batteries, with a minimum light intensity of over 3 candelas. 

The SM-3 weighs less than a pound (406g), including batteries and bracket, and measures 9.9 inches (253 mm) in length with a 2.2-inch (56 mm) diameter. Housed in a UV-resistant polycarbonate case, the SM-3 is supplied with a mounting bracket. The bracket fits the same hole pattern as that of the SM-2 Marker Light in case of upgrade.

The ACR SM-3 Automatic Buoy Marker Light is USCG-, MED- and SOLAS-approved for use anywhere in the world.

“ACR has been the choice of the United States Navy and Coast Guard, so its durability is put to the test every day on ships and oil rigs around the world,” stated Mikele D’Arcangelo, vice president of global marketing and product management for ACR Electronics.
