Projector lamps are essential components in projectors, providing the light needed to display images and videos on a screen. These lamps can vary in type, including UHP (Ultra High Performance) and LED (Light Emitting Diode), each offering different brightness levels and lifespans. The lifespan of a projector lamp typically ranges from 2,000 to 20,000 hours, depending on the type and usage. Regular maintenance, such as cleaning the lamp and ensuring proper ventilation, can help extend its life. When a lamp reaches the end of its life, it must be replaced to maintain optimal performance.
