This Dual LED Headlight is one of the brightest and lightest headlights on the market. It features two slim-line LED spot lights mounted vertically on a lightweight, adjustable headband. The light’s headband is conveniently and fully adjustable to enable the light to comfortably fit most head sizes. The dual LED light is attached to the headband with a very short articulating linkage enabling it to be adjusted to the optimum viewing position between the user’s eyes. Because LED lighting requires so little electricity, the light has a three "AA" battery power pack mounted directly on the headband. A model with a belt mounted Makita® or longer life is also available in two configurations - one with a single Makita® Battery and one with the Makita® Power Pack (two batteries and a charger).
