With 3 color temperatures for the white light, this head lamp offers maximum flexibility for all types of activities. Cool white gives an increased range and output, neutral white is balanced closer to daylight making it more natural to the eyes, and warm white is useful particularly in foggy conditions where the light will have better penetration. Range is up to 132m at the high mode.
There are four power levels for the main white lights, from my top output of 600 lumens, down to an ultra low of 6 lumens. The auxiliary red light has two outputs 15 lumens and 5 lumens, and a slow flashing mode.
