Incandescent light bulbs are the traditional style of light bulb with a twisting filament. Theyre often used as heat lamps due to the high temperatures produced as a by-product of generating electric light. When using incandescent light bulbs, only 5% of energy is used to create visible light.
Incandescent bulbs come in many fittings, including:
The standard incandescent bulb is a glass bulb structure that protects, most commonly, a tungsten filament. Incandescent bulbs are usually significantly cheaper than LEDs or any other fluorescent lamps to buy, however, LEDs are energy-saving by design.
Although incandescent bulbs are being phased out slowly, theyre still available to buy (often called rough-service or shock resistant varieties). In theory, though, these bulbs are meant solely for industrial use in industrial equipment like heat lamps.
