Product Details

SM-3 Self-Igniting Marker Life Buoy Light by ACR®. The SM-3 SOLAS approved lifebuoy marker light 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.

The SM-3 SOLAS lifebuoy light with a minimum light intensity of 3 candelas throughout its entire operating life, this high intensity LED strobe 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.

The supplied mounting bracket holds the SM-3 secure in the roughest of conditions but it is still readily accessible when needed in an emergency. Additionally, while the SM-3 and its bracket are significantly smaller than the SM-2 counterparts, the SM-3 bracket conveniently maintains the same mounting hole pattern as the SM-2, allowing for easy retrofit with no additional adapter plate required.

The SM-3 is USCG/MED/SOLAS approved for use around the world and this durable LED marker light, therefore, provides an excellent option for vessels needing to meet USCG and SOLAS carriage requirements for lifebuoy self-igniting lights. As per USCG and SOLAS requirements for passenger and cargo vessels, at least one-half of the total number of lifebuoys on the vessel must be fitted with a self-igniting light. Minimum carriage requirements are based on the length of the vessel and can range from a minimum of four to a minimum of fifteen lifebuoys with self-igniting lights per vessel.

Rugged design leads to the greater flexibility of use. While the SOLAS approval only calls for a 30-meter drop test, the SM-3 has been drop tested to 76 meters. This makes the SM-3 a versatile option for use on a variety of platforms or vessels of different sizes.

With its easily replaceable Lithium AA battery power source, the SM-3 will give years of service and be ready when called upon.

Bright Lighting, Good Strobe
The light works well. I have it close by because you can never be too safe on the water. First of all, I checked it. It is really waterproof. Bright lighting - very nice. Very useful thing, many times rescued.

Better than Nothing
"Meets coast guard minimums" that's for sure. Just purchased a Firefly Pro. I do not understand the weakness of the light. I want a strobe that will run for an hour that can be seen from OUTERSPACE. EVERYONE carries a PLB nowadays, so within an hour I will have a helicopter overhead. We don't need 56 hours of weak light, we need an hour of a strobe so bright that anyone looking anywhere near our location will see it even with hungover blurred vision. Get going ACR.

Practical and Affordable Light
I like this emergency light. It is bright. Compact design. Plus, it is waterproof. The manufacturer promises the LED will work for 120 hours. Rather good. I also love that this light is versatile in use – I can attach it to my clothing, bag or belt as it has special straps and a clip.
