SM-3 SOLAS Lifebuoy Marker Light 

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 30°C (86°F) or over 24 hours at -1°C (30°F).  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. 

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. 

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. 

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

Fantastic soap for the dermatitis and eczema prone
You guyyyyysss, my hands have no dry, itchy spots right now. None. This is remarkable because before now I have for years had issues with eczema/contact dermatitis patches that have at times (aka: most times) been pretty unbearable. To say that I’m overjoyed to have found a natural soap that truly works for me is an understatement. When you use this, you can feel that it’s moisturizing your skin. It’s fantastic. If you haven’t tried it, do yourself a favor and get yourself a bar. I’m wondering now if I can use it on my entire body and to wash my hair. That’s probably a little overboard, but it’s that good and now that I’ve used it I suspect all my skin problems are contact dermatitis that could be solved by the right soap/shampoo.

Best I’ve found yet for facial psoriasis
Anyone who has facial psoriasis will tell you there are not a lot of products that you can put on your face without irritation or flareups. This soap is just what I needed. There are no irritating chemicals or perfumes in this soap. I have read other reviews that the soap does not last very long but there is a way to use it to make it last. First, I wet my face and then I wet my fingertips and rub my finger tips across the dry bar of soap and then lightly rub my face with my fingertips softening the plaques and then lightly wash with a soft cotton washcloth. It is not really moisturizing but not over drying either. I follow up with an organic vegetable-based glycerin oil to moisturize. This is the best product I have found yet.

Heals skin
It definitely dries out your skin quickly but I do recommend moisture so the skin won’t crack or you get open cuts as your dermatitis is healing. I have dermatitis really bad where my skin drys and hurts when I have a cut, So far it’s working as intended.
