There are different types of bulbs that can be used in lamps, including incandescent lamps, LED lamps, CFL lamps (compact fluorescent lamps) and halogen lamps. Each of these types of bulbs has its own advantages and disadvantages in terms of brightness, energy efficiency, and lifespan. Incandescent lamps are the least energy efficient and have the shortest lifespan, while LED lamps have the longest lifespan and the highest energy efficiency. CFL lamps are in between incandescent and LED lamps in terms of energy efficiency and lifespan. Halogen lamps have a longer life and higher brightness than incandescent lamps, but lower than LED lamps.
