The Zebralight H600W MK IV head torch has a maximum output of 1400 lumens from the Cree XHP35 LED and is powered by 1 x 18650 rechargeable Li-ion battery. The headlamp features a nominal CCT 4500K providing a warm, neutral light; the higher the Kelvin (K), the cooler the beam temperature.
In addition to the three main levels of High, Medium and Low, the H600W MK IV features a beacon and strobe mode. Each main level can be programmed to one of its two sub-levels. The second sub-level of each main levels can be further programmed to different brightness levels.
One short click on the head torch turns on the light to High and again to switch it off; two short-click turns on the light to Mid and three short-click turns on the light to the special modes. Press and hold the switch (for over 0.6 seconds) to cycle through Low, then Mid and High, simply releasing at the desired level.
For more advance operation and configuration, press and hold to cycle from Low to Mid to High, and release at the desired level to set. Double click the switch to toggle and select between the two sub-levels for that main level. Sub-level selections for the 3 main levels are memorised after the light is turned off and through battery changes.
The second sub-level (H2, M2 and L2) of each main levels can be further programmed to different brightness levels. At a main level, double-click 6 times to start configuration. On subsequent double-clicks the light will cycle through different brightness levels. When a configuration is finished, short click to turn off the light. The selections for the second sub-levels are memorized after the light is turned off and through battery changes.
