We have taken the LED II head and combined it with our 21-volt belt light pack. The head is light weight with an aluminum ring as its base. It features two super bright LED that will shine the tallest trees. It is light, it is bright and it has a 4 position click switch with a standard phono jack on the cord. It has a very focused beam that throws a tight spot. Add to this exceptional burn times;
Position 1: over 200 hours
Position 2: 60 hours
Position 3: 18 hours
Position 4: 7 hours

We think this light has a lot of features you will like. This head will burn when connected to any 12 to 21 volt battery pack but you will not be able to regulate the brightness without a special switch. However, you do not have to be concerned with burning this head out by plugging into the wrong battery pack. It will not damage it. We have incorporated the LED switch into this belt pack. The battery pack is a 21-volt nimh battery and is rated at 4000 mAH and weighs 2.5 pounds. Plus it has spotlight jacks if you want to add a spotlight. Comes standard with smart charger. Two-year warranty on LED, 3 years on battery pack. Contact us with any questions.
