KC3D-Ex has two LED light sources. The Main LED, a high-power LED located in the middle of the reflector, is for both normal and high-beam illumination. The Emergency LED, a low power LED located on the brim of the reflector, can operate for an extended period during an emergency.
KC3D-Ex features a superior illumination in just 140g, even less than the headpiece of a traditional caplamp. It is suitable for most underground mining applications.

Operations

There are three operating modes.

Main mode (level 2): For normal working operation, delivering good illumination in excess of 14 hours duration.
High-beam mode (level 3): Strong light beam for long distance projection, spotting, etc. Should only be used for short periods because the heavier battery drain shortens light duration in this Mode to around 8 hours.
Auxiliary mode (level 1): Power saving for long operation and low level illumination.
Off: The Caplamp is switched off.

– Always starts up from the Main Mode when switched on.
– By toggling the operating button the Caplamp goes through Main Mode > High-Beam Mode > Auxiliary Mode > Off Mode
– Holding  the button down for 2 seconds switches the Caplamp off directly.
– If the lamp is kept in the High-beam Mode for 20 minutes, it will automatically goes to the Main Mode.
