LED bulbs produce light through semiconductor materials, whereas incandescent bulbs use heated filaments, and fluorescent bulbs rely on electrical discharge through ionized gas. LED bulbs have a significantly longer lifespan and lower energy consumption compared to incandescent and fluorescent options, making them the most efficient choice. They also emit less heat and are more environmentally friendly, contrasting with the higher heat emissions and energy loss of other bulb types.

2. LED bulb produces illumination by movement of electrons
through semiconductor material.
Incandescent light is emitted by heating the filament
present in the bulb.
Fluorescent bulbs generate light by sending an electrical
discharge through an ionized gas.
