The lamp will accumulate a lot of heat when used at relatively high modes for
extended periods. When the lamp reaches a high temperature, the lamp will
automatically step down a few lumens to reduce the temperature. When the
temperature drops, it will then allow the user for the reselection of the modes.
2. Low-voltage Warning
When the voltage level drops below the preset level, the headlamp is programmed
to downshift to a lower brightness level until Low output is reached. When this
happens in Low output mode, one of the charging indicators blinks blue constantly
