Abstract
A light emitting diode (LED) work light and associated method of controlling the LED work light. The LED work light includes a power source, a casing including a handle section, at least one LED mounted to illuminate light from the casing, at least one lens forward of the LEDs to focus light from the LEDs, a control switch designated to at least turn on and turn off the LEDs, and a controller. The controller may be configured to, in response to activation of the control switch, provide control of the power source to the LEDs to transition from a first illumination state to a second illumination state of the illumination of the LEDs, the transition being illumination defined by a specified function over time defined to slow a transition time of the transition.
