AL250M: The AL250 light is now mini-sized! The AL250M is smaller in size than the previous version with the same great performance. This small light boasts a strong 250 lumen beam at only 8 degrees – making it a powerful penetrating light to cut through murky water. With an anti-corrosive aluminum alloy body and a double o-ring seal, this small light is rugged and durable for any diving use. The AL250M comes with a stand-alone 3AAA battery holder (Alkaline or NiMH batteries not included), and also comes with an adjustable lanyard.
