Classification: CPC F  H | IPC F

Claim 0:
1. A light tower comprising:
a base;
an extendible mast coupled to the base, wherein the extendible mast is configured to move between a lowered position and a raised position;
a battery pack supported on the base and including a plurality of lithium-ion battery cells;
a light assembly including a plurality of light emitting diodes, the light assembly coupled to the extendible mast and the light emitting diodes electrically coupled to the battery pack;
a user interface configured to receive inputs and display information;
a plurality of dimmable drivers coupled to the light assembly;
a light sensor configured to detect a brightness of the light assembly; and
a controller in communication with the battery pack, the light assembly, and the user interface, the controller being configured to:
instruct the user interface to display a runtime based on a light intensity of the plurality of light emitting diodes;
receive a light intensity change input from the user interface;
receive the brightness of the light assembly from the light sensor and, in response, instruct the plurality of dimming drivers to change the brightness of the light assembly;
change the light intensity of the plurality of light emitting diodes by adjusting a power provided by the battery pack to the light emitting diodes in response to the light intensity change input; and
display on the user interface an updated runtime resulting from the change of the light intensity of the plurality of light emitting diodes.
