8000 lm Laser Projector. The use of laser light sources can achieve up to 20,000 hours of maintenance-free operation, eliminating the need to replace light sources, ensuring long-lasting and highly reliable operation of the machine, and greatly reducing TCO (comprehensive use cost). At the same time, the effective dust-proof structure of the closed engine is used, and the intrusion of garbage and dust can be reduced through the reasonable structure design and rubber protection of the contact interface, so that the projector can be used in a wider environment.
