An improved LED provides power efficient lighting while accepting a wide range of input voltages. The improved LED may comprise a controller that may measure a voltage, current, or other characteristics of input power and modify operation of the improved LED accordingly, such as to accept significantly more voltage or significantly less voltage while providing consistent light output. This allows light bulbs or other lighting to be easily manufactured with the improved LED. The improved LED may comprise the controller and one or more LED dies enclosed by a substrate and lens structure. Depending on the configuration of the controller, the improved LED may also provide time, temperature, and other measurement/response functions to help ensure consistent light output.
