In this PowerPoint, the three main types of electric bulbs have been explained, with 10 major differences among them. Bulb types include LED, fluorescent, and incandescent.

1. LED Incandescent Fluorescent
7 Watt 14 Watt
60 Watt

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.
