Don't get lost in the technical jargon.  Zebralights are among the most popular lights in caving and for a good reason. The H53Fc is the most ideal light for an "around-the-neck" backup light.  Running on a single AA battery, the H53Fc is ultralight yet still manages to carry a large punch.  This light is a great choice whether it be underground or camping.

Double click to toggle and select between the two sub-levels for that main level. Sub-level selections for the 3 main levels are memorized 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. Short click to turn off the light when finishing configurations. The selections for the second sub-levels are memorized after the light is turned off and through battery changes.
This light uses the main LED (flashing 1 to 4 times) to indicate the estimated remaining capacity of the battery. To start the battery indicator, (from Off) short-click 4 times without pause.
Beacon-strobe mode can be accessed from 3 short-clicks when the light is Off. Once in the beacon-strobe mode, you can double-click to cycle through different types of beacons and strobes. Beacon-strobe settings are memorized when the light is turned off and through battery changes.
