LED (Light-Emitting Diode) based lighting has been around for a little over 20 years and it continues to take over more and more of the general lighting market.
The technology is based on the light emitting diode, but the diode itself is a single component that requires supporting digital circuitry to control the light output.
The design and capabilities vary from simple on/off up to complex control systems.
At the higher end, the LED “bulb” may have a microprocessor...
