The lamp will accumulate a lot of heat when used at relatively high output levels for
extended periods. When the lamp reaches a temperature of 60°C or above, the lamp
will automatically step down a few lumens to reduce the temperature.

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.

Solution: Clean the contact points with a cotton swab soaked in rubbing alcohol.
