What is the difference between incandescent and LED light bulbs?
user
Two common types of bulbs are incandescent and LED.  Incandescent bulbs produce light by heating a thin tungsten wire filament, which glows red when current flows through it.  In contrast, LED bulbs use light-emitting diodes, which generate light without heating a filament.  LEDs are usually more energy efficient than incandescents, because LEDs use less electricity.  So incandescent bulbs are a common choice for lighting, but LED bulbs are gaining more popularity, because they are energy efficient.

I like cheaper electric bills. What about smart bulbs? Do you know anything about them?
