What are incandescent and fluorescent considered?
Correct Incorrect Incandescent light bulbs contain a thin filament made of tungsten, encased in a glass bulb, and are considered the traditional type of bulb, though they are less energy-efficient. In contrast, fluorescent bulbs operate with electrodes, argon gas, and mercury vapor, making them significantly more energy-efficient, about four to six times more than incandescent bulbs.
