This headlamp features 3 position lighting with 1 C4 LED bulb, 2 green LED and another separate green LED. This light will help you with close up work as well as distance work. The head tilts 90 degrees to adjust the angle of the light and the light will run up to 150 when using a single LED. The user can decide from three lighting modes: C4 LED for super-bright light with strong beam distance, three 5mm safety green LEDs for intensely bright green beam and longer run time, and one 5mm safety green LED for extended run times and when a less intense beam is ideal. Keep this headlamp with you the next time you need illumination.
