7000 lm Laser LCD Projector. The laser light source engineering machine developed by Maxell has high brightness and a light source life of 20,000 hours (standard mode). The light source assembly is sealed to prevent dust from entering the optical core components such as fluorescent wheels and lenses that may affect the use effect and service life, effectively reducing maintenance costs and ensuring long-term continuous operation. More suitable for the engineering market that needs a long time to use! Whether it is exhibitions or electronic billboards, it can be more calm.
