Will laser projector brightness degrade over time?
Direct answerYes, but far more slowly than lamp projectors. A laser light source fades gradually instead of dropping suddenly, with a rated life of about 20,000 hours in normal mode and up to 30,000 hours in eco mode.
What Degradation Actually Looks Like
| Item | Lamp projector | Laser projector |
|---|---|---|
| Typical light source life | About 2,000 hours | 20,000 hours normal / 30,000 hours eco |
| Failure pattern | Sudden end of life, lamp replacement | Gradual fade over the rated life |
| Colour drift over time | Noticeable shift as the lamp ages | Stable colour output across the life span |
| Routine cost | Repeated lamp purchases | No lamp replacement cost |
How to Protect Brightness Long Term
- Keep the air intake and filters clean so heat does not build up inside the housing
- Use eco mode for daily operation and reserve full output for peak show moments
- Maintain stable ambient temperature, especially in outdoor cabinets
- Schedule an annual output check so the effect level can be adjusted before visitors notice
Degradation is gradual and predictable, so long-running venues can plan a brightness budget instead of facing sudden failures.
