Abstract
An LED-based light includes one or more LEDs, a sensor arranged to detect a brightness level in an area resulting from the combination of light emitted by the LEDs with light from at least one ambient light source other than the LEDs, and operable to output a signal corresponding to the detected brightness level, a controller operable to regulate an amount of power provided to the LEDs in response to the signal, a light transmitting housing for the LEDs, the sensor and the controller and a connector shaped for connection with a light socket disposed at an end of the housing.

-20. (canceled)
A system comprising:
- a controller configured to be communicatively coupled to a sensor and a lighting device having a plurality of LEDs, wherein the controller is operable to:
- receive, from the sensor, a first sensor signal indicating a brightness of an environment of the lighting device during a first time interval during which the LEDs are switched on;
- receive, from the sensor, a second sensor signal indicating a brightness of the environment of the lighting device during a second time interval during which the LEDs are switched off;
- determine, based on the first sensor signal and the second signal, that the lighting device should be replaced;
- responsive to determining that the lighting device should be replaced, causing the lighting device to visually indicate that the lighting device should be replaced.
