Incandescent vs. Fluorescent: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Updated on October 14, 2023
Incandescent lights produce light through heating a filament, while fluorescent lights emit light via a phosphorescent coating and UV light.

Key Differences

Incandescent bulbs work by passing electricity through a thin wire filament, causing it to heat up and glow, thus emitting light. In contrast, fluorescent lights contain a low-pressure mercury vapor that produces ultraviolet light, which then causes a phosphorescent coating inside the bulb to glow.

When it comes to energy efficiency, incandescent bulbs tend to be less efficient. A significant portion of their energy is wasted as heat. On the other hand, fluorescent lights are more energy-efficient as they convert a higher ratio of energy into visible light, producing less waste heat.

The lifespan of incandescent bulbs is generally shorter compared to their fluorescent counterparts. While an incandescent bulb may last around 1,000 hours, a fluorescent bulb can last up to 10,000 hours or more.

Incandescent bulbs produce a warm, continuous light that can be dimmed easily. Conversely, fluorescent lights may have a cooler tone, can sometimes flicker, and not all are compatible with dimming switches.

In terms of environmental impact, fluorescent bulbs contain a small amount of mercury, making their disposal more of a concern than incandescent bulbs. However, the increased energy efficiency of fluorescent lights can lead to a reduced carbon footprint over their operational lifespan.
