What is an Incandescent light bulb?
A. Incandescent lamps are the original light source where a tungsten wire filament heats and glows. It is the most common light source with a low color temperature and high CRI casting a warm light. These lamps are inexpensive and are available in a wide variety of sizes and wattages. However, they are not energy efficient because most of the energy they consume is given off as heat.
