Long-life Lamp Reduces Cost

Breakthrough technology extends lamp replacement to 20,000 hours*. Longer lamp-life is achieved by reducing degradation and by improving cooling capabilities. Enjoy bright picture quality, low TCO, and less downtime for maintenance.

* Lamp life is approximately 20,000 hours in Eco Mode and approximately 10,000 hours in Normal/Quiet Mode. Lamp replacement time varies depending on operating environment and usage conditions.

Daylight View Lite

Daylight View Lite optimizes color and brightness according to ambient lighting levels. This function is easily accessed using the supplied remote control.

Quiet 30 dB Operation for Distraction-free Viewing

Operating noise is as low as 30 dB*, reducing the chance of distraction during presentations or quiet video scenes.

* With Lamp Mode is set to Quiet.

Easy Setup and Management

1.2x Zoom Versatility

The projector includes a 1.2x zoom lens to support a wide range of projection throw-distances. This is useful when presenting in different installation environments.

Note: Above throw-distance is for PT-LW375/LW335 in 16:10 aspect ratio producing a 100-inch image. PT-LB425/LB385/LB355/LB305 requires 3.0 m–3.6 m throw-distance and 4:3 aspect ratio for a 100-inch image.

Corner Keystone Correction for Angled Projection

If on-site conditions call for off-axis projection, simply designate four screen corners and Horizontal & Vertical Corner Keystone Correction performs necessary adjustments for distortion-free image presentation.

* PT-LB305 features vertical keystone correction only.

Curved Screen Correction

Barrel and pincushion distortions are easily corrected when projecting onto a curved screen surface such as black- or whiteboards.

* Excluding PT-LB305.

Easy Lamp and Filter Replacement

To reduce hassle, the filter can be replaced via the side and the lamp from the top of the projector. There’s no need to remove the unit from its ceiling mount for periodic maintenance.

Multi Monitoring & Control Software

This free Panasonic software offers monitoring and control of up to 2,048 devices over a LAN network from a single PC. For monitoring, status for individual devices can be listed in groups, with more detailed information shown separately. Control functions include power ON/OFF.
