Are light bulbs inorganic or organic?

Light bulbs are primarily made of inorganic materials. The glass casing is composed of silica (sand), while the metal components, such as the base and filament (in incandescent bulbs), are typically made from metals like tungsten or aluminum. Some light bulbs, like compact fluorescents and LEDs, also contain inorganic phosphors and semiconductors. Overall, the materials used in light bulbs are largely inorganic in nature.
