This new light source requires no maintenance for approximately 20,000 hours.^*1 In many cases, this means no maintenance until your next refresh cycle. Naturally, there are no lamp burnout problems during use, so reliability is further increased. There is also no filter to clean due to carefully engineered sealed optics.

The LED/Laser-combined light source has a higher level of colour purity than an ordinary lamp, allowing it to achieve colour reproduction with wider colour space. Colours are more vibrant than those of conventional projectors.

The area between the LED/Laser to the DLP™ chip and prism is hermetically sealed to form an airtight structure for the optical block, the heart of the projector. This resists the effects of dust and other particles in the air, and enables use of the projector in a wide range of environments.

A lens-centered, symmetrical design provides ease of installation, eliminating the need for any special considerations when planning the installation site.

Equipped with a DIGITAL LINK terminal, the PT-RW430U allows transmission of HDMI, uncompressed HD digital video, audio and control signals (Ethernet, RS-232C) for up to 100 meters (328 feet) through a single CAT5e (STP) cable or higher. This simplifies cabling and system upgrades, making it ideal for ceiling-mounted and other permanent installations.
