Projector BenQ LH655C, 4000AL 1080P Laser, 15W Speaker, 16:9 ratio

BenQ LH655C is a laser Full HD projector with 4000 ANSI lumens of brightness, designed for clear presentations and highly visible images even in rooms with natural daylight. The Laser Phosphor light source is mercury-free and provides up to 20,000 hours of operation in Normal mode or 30,000 hours in Eco mode, while the built-in 15W speaker enables presentations without the need for a separate audio system.

The sealed optical system limits dust ingress into the optical block, which is important for long-term operation in office and educational environments. DLP technology with a 0.65" DMD chip, Full HD resolution, and 4000 ANSI lumens delivers detailed images with sufficient brightness for presentations, graphics, and video content. The 1.48–1.62 throw ratio and 1.1x optical zoom make it easier to adapt the projector to the specific room, while 2D keystone correction of up to ±40° allows image geometry to be corrected when the projector is not ideally aligned with the screen.

With the optional DM01 dongle, the projector can be integrated into BenQ DMS for centralized management and remote firmware updates, which is practical when managing multiple devices. For wireless presentations, the optional QP30 WiFi Screen Casting dongle is available, while the two HDMI and two USB ports provide direct connectivity to various content sources. The built-in Security Bar and Kensington Lock provide additional physical security options for installations in publicly accessible areas.

The BenQ LH655C is suitable for conference and meeting rooms, classrooms, and office spaces, including environments with natural daylight where high brightness is an important factor. Its compact 279.2 x 224.8 x 120.5 mm chassis and 3.0 kg weight facilitate positioning and installation without requiring significant space.

The combination of 4000 ANSI lumens, Full HD resolution, a laser light source, sealed optics, and centralized management capabilities makes the LH655C a practical solution for professional presentation environments requiring predictable operation and straightforward maintenance.
