Which of the following lamp types is known for its longevity and brightness?

Discharge lamps are recognized for their significant longevity and brightness compared to other types of lighting. These lamps operate by passing an electric current through a gas or vapor, which produces light. They can achieve high levels of brightness, making them suitable for large spaces and outdoor areas, and they also have a much longer lifespan than incandescent and halogen lamps.

This extended lifespan is a result of the technology involved; for instance, high-intensity discharge (HID) lamps can last from 10,000 to 24,000 hours, depending on the specific type, while fluorescent lamps typically last around 7,000 to 15,000 hours. In contrast, incandescent bulbs last only about 1,000 hours, and halogen lamps offer slightly better longevity than traditional incandescent bulbs but still fall short when compared to discharge lamps.

Thus, the attributes of longevity and brightness clearly define discharge lamps as the superior choice in this context.
