You get what you pay for and in the case of generic lamps it’s usually a long list of problems.

They’ve created using toxic substances such as Krypton-85 (which is carcinogenic to humans). “Compatible” lamps also  have a shorter life span so can actually cost more money in the long run.

It’s worth the few extra dollars to eliminate potential problems and have a lamp built to work properly with your BenQ CP120 sensitive mechanisms.
