When the lamp power is set to AUTO, it can operate for up to 7,500 hours* without needing to be replaced. This also helps reduce maintenance and operating costs.
NOTE: When set to AUTO, the Projector automatically controls the picture by adjusting the lamp to optimal output power.
* This is the maximum value when the lamp power is set to Auto mode where the lamp is turned on for 2 hours and off for 0.25 hours.
If the lamp is turned on more times or kept on for a long time, the lamp replacement cycle will shorten.
The usage environment affects the duration of the lamp.
The PT-TW331R / PT-TW330 / PT-TX301R / PT-TX300 can operate for up to 7,500 hours.
A Full 3,100 lm of Brightness and 7,500:1 Contrast in a Compact 2.7kg (6.0 lbs) Body
A remarkable 3,100 lm of brightness and 7,500:1 contrast have been achieved in a compact, easy-to-carry body, weighing only 2.7kg (6.0 lbs) or less. Bright, clear images enhance a variety of viewing situations and applications. And the compact, lightweight body makes it easy to carry from room to room, or to the client's office for an on-site presentation.
Quiet 29-dB* Design Does Not Interrupt Meetings or Classes
The quiet design keeps noise levels down to 29 dB,* so the sound of the cooling fan is hardly noticeable. This helps the audience to keep their attention on the speech when someone is giving a presentation, or on the screen images during quiet scenes.
* When the lamp power is set to Eco2, or Eco for the PT-TW331REA.
The Interactive Function Allows Writing on a Projected Image*
You can write or draw figures on the projected image with the Interactive Pen / Pointer. The scanning camera frame rate of the PT-TW331R / PT-TX301R is twice as high as that of our existing products**; ensures smoother writing. In addition, two users can write simultaneously, to make classes and presentations more effective. It is easy to store the words and figures in a computer for information sharing.
* Interactive function: PT-TW331R / PT-TX301R only.
** The frame rate of PT-TW331R / PT-TX301R is 60 fps.

Intelligent Lamp Control System Reduces Power Consumption
When the lamp power is set to AUTO, the Intelligent Lamp Control system automatically adjusts the lamp output in accordancewith the brightness of the projected image and reduces it by up to 70%.* It also combines with colour shift correction,which corrects the shift in the colour balance that occurs when the lamp output drops.
As a result, power consumption is effectively reduced while excellent colour reproduction is maintained.
* For the PT-TW331R / PT-TW330 / PT-TX301R / PT-TX300.
Environmentally Friendly Standby Power Consumption of Only 0.5 W*
The standby power consumption is as low as 0.5 W*, reducing running costs and the effects on the environment.
*When [LAN (Standby)] / VGA Out (Standby)] / [In Standby Mode (Audio)] are all set to [Off].
