When to Change a Projector Bulb
Most projector lamps last between 1,500 and 2,000 hours, but some can last up to 5,000 hours. Most projectors will need one to two bulb swaps during this time.
Time To Replace It
Unlike other bulbs that go out once expended, the high-pressure mercury and xenon used in projector lamps cause bulbs to dim over time. Once the lamp light is at about half its original luminescence, it’s time to replace it. You can continue to use the bulb until complete failure, but doing so impacts image quality.
Useful Hours
Check how many useful hours your lamp has left in the menu options of the projector. User manuals have specific steps for this process.
Manufacturers and product testers judge life expectancy based on a bell curve of a bulb. Most projector lamps come with a 90-day or 3-month warranty instead of a warranty that reflects its rated life span.
