Abstract
A lighting apparatus includes a light source operable to emit different levels of brightness, and a user interface configured to be selectively actuated by a user to turn the light source off and on. When the light source is off and the user interface is actuated for a first amount of time, the light source turns on in a first mode in which the light source emits a first level of brightness. When the light source is off and the user interface is actuated for a second amount of time that is different from the first amount of time, the light source turns on in an ultra-low mode in which the light source emits a second level of brightness.
