Which lighting type typically has the shortest lifespan?

The option identified as correct refers to incandescent lamps, which indeed have the shortest lifespan compared to the other lighting types listed. Incandescent bulbs are primarily designed to produce light by passing electricity through a filament, which then heats up and emits light. This process generates a significant amount of heat, which contributes to the wear and tear on the filament, ultimately leading to burnout. Typically, incandescent lamps last around 1,000 hours.

In contrast, halogen lamps, while also based on the incandescent design, tend to last slightly longer due to the presence of a halogen gas that recycles the evaporated tungsten back onto the filament. LED lamps stand out for their exceptional longevity, often lasting tens of thousands of hours due to their energy-efficient technology and minimal heat production. Similarly, fluorescent lamps have a lifespan that typically ranges from 7,000 to 15,000 hours, significantly surpassing that of incandescent bulbs. Understanding the lifespan differences among these lighting types is crucial for effective interior design choices and energy management.
