The iSEO3 is a robust, high quality work head lamp designed for professionals who need to use a light source often. It features a premium Power LED on the front housed inside a lightweight but strong polycarbonate housing. The LEDs offers bright white or glare-free red light, as well as three interchangeable Smart Light Technology light options: Power, Low Power and Signal. On Power setting the iSEO3 will project brilliant light up to 100 metres at 100 lumens. To preserve battery life a Low Power option gives up to 40 hours burn time. The lamp head can be rotated 60 degrees, which helps reduce neck strain, and the internal reflector lens is equipped with Ledlenser's patented Advanced Focus System for efficient, even lighting all the way through from spot to flood beam. The simple twist focus allows the light to be instantly adjusted with just one hand, while a Transport Lock prevents accidental battery discharge and the head lamp from switching on accidentally when not in use. The distinctive yellow-black high-comfort headband makes the iSEO3 easy to find in the most cluttered working environment. The iSEO3 takes three AAA batteries (included) and is supplied with a pouch for protective storage.
