LCD and DLP projectors typically have a lamp life between 2000-4000 hours. This specification is actually referring to the 'half-life' of the lamp. The half-life is the point where the lamp is half as bright as it was new. The lamp will still work at its half-life, but it will continue to gradually lose brightness. Longer lamp life means less expense in maintaining your projector.
If you are planning to use your projector to replace your current television, lamp replacement cost should be factored into your purchase. Replacement lamps run approximately $200-$400.
If your projector will be used primarily for watching movies and special events, lamp life will not be quite as important. But you may still want to factor the cost of a replacement lamp into your purchase. The average projector used in this manner runs approximately 8 hours a week.
- Lamps typically last between 2000-4000 hours.
- Replacement lamps cost between $200-$400.
- Regular filter cleaning and proper operation will improve lamp life.
- The average projector used for movies and special events runs 8 hours a week. At this rate, the a lamp will last aproximately 4.8 years.
Quick Tip:
If you purchase a spare lamp with your projector, run it in your projector for a few hours first, then store it somewhere cool and dark. Lamp warranties begin from the day of purchase, not from the day of use. If a lamp is faulty, it will usually fail within the first 4 to 10 hours of opperation.
