Bright, Vibrant Large-Screen Images
A Full 16,000 lm of Brightness
and 2,500:1 Contrast
The 4-Lamp Optical System uses high-output, 380 W UHM lamps to
deliver remarkable 16,000-lm brightness. And the contrast ratio is a
high 2,500:1, to ensure bright, crisp, large-screen projection.
High 13,000-lm Brightness
and 4,000:1 Contrast
The 2-Lamp Optical System uses high-output, 380 W UHM lamps to
produce high brightness of 13,000 lm. Contrast is also high at 4,000:1.
Images are sharp and crisp.
Full 10-Bit Image Processing
System
The use of a full 10-bit image processing system provides smooth tonal
expression. For example, skin tones appear natural and true to life.
High Reliability for Long-Time Use
The Multi-Lamp Optical System
Enables Stable, Extended Operation
Even if one lamp goes out during use, the other lamps continue, so
projection is not interrupted. Lamp Relay mode also allows long-time,
continuous operation.

Highly Durable Optical Engine
Ensures Excellent Long-Time
Image Quality
The LCD panels and polarizers inside the LCD projector's optical block
tend to degrade over time. Their degradation adversely affects image
quality. Inorganic materials are used for the LCD panels, and for the
polarizers that are prone to degradation, to resist time-related
changes in the optical block, therefore achieving a replacement cycle
of up to 10,000 hours.
*1 The values above are maximum values when they are used in cycles of being turned on for 2 hours and off for 0.25 hours. When the lamps are turned on and off more frequently, the lamp replacement
cycle is shortened. The usage environment affects the lamp replacement cycle. *2 With the lamp power set to Normal. The usage environment affects the duration of the filter. *3 Electrostatic filters.
*4 When washing with water, please follow the procedures listed in the operating instructions. Also, we recommend replacing the filter with a new one after it has been washed and reused twice. If the filter
is not sufficiently clean after washing, replace it with a new one.

Excellent Colors with
Pure Color Control
It is inherently difficult for LCD projectors to attain both high brightness
and superb color reproduction. For this reason, in addition to the three
conventional LCD panels that control the light intensity for the red, blue
and green primary colors, the PT-EX16K/EX12K also features a Pure
Color Control function that independently controls the light intensity of
yellow coloring. This provides rich overall color expression while
maintaining brightness.

maintenance hassles. The filter is also replaced from the front, so
there is no need to detach the projector from its mounting bracket in
ceiling-mounted applications.
The Long-Lasting Eco Filter with
User-Friendly Maintenance
The PT-EX12K features the Eco Filter, which efficiently captures dust
and requires no replacement for up to 12,000 hours.*

Micro Cut Filters*
that use an ion effect to collect extremely small
dust particles. These large-surface, pleated filters have a high dust
collecting performance. In addition to its long replacement cycle, the
Eco Filter can be washed with water*
increasing its ecological performance.
The Eco Filter can also be removed through
the top panel of the projector, enabling filter
replacement on ceiling-mounted projectors
without having to detach the projector from
its mounting bracket.
Optional Smoke Cut Filter Provides Protection
from Fine Smoke Particles
The projector can be equipped with an optional Smoke Cut Filter
ET-SFE16 to prevent the entry of not only dust but also fine smoke
particles, such as those used for special effects at events and stage
performances.
