Excellent Performance in a Compact Body
High Brightness and High Contrast in a Lightweight Body
A brightness level ranging from 3,100 lm* to 4,100 lm* and contrast ratio of 16,000:1 have been achieved in a compact lightweight body. Clear and bright images enhance the learning and working experience.
* Brightness ratings for models in the PT-LB423 Series are as follows: PT-LB423 (4,100 lm), PT-LB383 (3,800 lm), PT-LB353 (3,300 lm), PT-LW373 (3,600 lm), and PT-LW333 (3,100 lm), PT-LB303 (3,100 lm)
A Maximum 10,000-hour *1 Lamp Replacement Cycle and 10,000-hour *2 Air Filter Replacement Cycle
The PT-LB423 Series has a maximum lamp replacement cycle of 10,000 hours.*1 The air filter also has a replacement cycle of 10,000 hours.*2 This reduces maintenance hassles for long periods of use, and helps to lower maintenance costs and reduce environmental impact.
*1 This is the maximum value when the lamp power is set to Eco2. The usage environment affects the lamp replacement cycle. *2 The usage environment affects the duration of the filter.
Daylight View Lite
The Daylight View Lite function can be activated from the remote control for easy and comfortable viewing during presentations and lectures in a bright room.
Quiet 28-dB* Design Helps to Hold Viewers´Attention
The noise level is as low as 28 dB*. This helps your audience to keep their attention on the discussion or on the screen images during quiet scenes.
* Lamp control: Eco2
Ease of Installation
Corner Keystone Correction Enables Angeld Projection
All you need to do is designate for points as the corner of the projected image, and this function easily carries out horizontal and vertical keystone correction.
Easy Remote Monitoring and Control over a LAN
Web browser on a computer connected through a wired LAN system lets you remotely operate projectors and check their status.In addition, Multi Monitoring and Control Software is available for monitoring and controlling multiple Panasonic projectors from a single PC.The wired LAN terminal is compatible with PJLink™ (class1), an open protocol that is used by many manufacturers, to enable integrated control of systems that contain different brands of projectors.
1.2x Zoom Lens Allows Flexible Installation
The PT-LB423 Series includes a 1.2x zoom lens to support a wide range of projection throw-distances. This is useful when presenting in rooms of different sizes.
Easy Lamp and Air Filter Replacement Simplifies Maintenance
For easier maintenance, you can replace the lamp from the top and the air filter from the side, even after the projector is installed on the ceiling. This eliminates the need to detach the projector from its mounting bracket in ceiling-mounted applications.
