Zitat:

The main advantage of laser projectors is they last much, much longer than lamp projectors. The Xiaomi Mi Laser Projector has a rated life of 25,000 hours. If you use the projector for four hours a day, you’ll be able to use it for more than 17 years before needing to buy another projector.

You will need to replace the entire projector, though: you can’t just replace the laser inside like you can a lamp. That’s probably not a huge deal since there will surely be other technological improvements over the years that you own the projector, making a new upgrade well worth it.

The lamp, or laser, lasts approx. 20,000 to 25,000 hours, so you will hardly have the "pleasure" of replacing the "lamp". ... Regards Jürg
