Overview

The LS740W is a premium installation-grade laser projector designed for environments where brightness, durability and flexibility matter — such as lecture theatres, corporate boardrooms, digital signage and immersive installations.

Its laser-phosphor light engine offers up to 30,000 hours of operation in Eco mode, dramatically reducing downtime and ongoing maintenance compared to traditional lamp-based projectors.
