Laser projection technology makes your office more eco-friendly as it fosters sustainability. Our green mercury-free LH650 projector is not only equipped with BenQ SmartEco 2.0 to save power and reduce maintenance costs but its compact size and high brightness also ensure an efficient and uninterrupted meeting experience.
