Good TCO & Energy Efficient
20,000 Hours Maintenance-free Operation
Thanks to its laser light source with control technology,
long-life LCD panel, and advanced filter system, the VPL-FHZ55
offers up to 20,000 hours of operation without maintenance
or replacement. Virtually zero maintenance requirements
and a range of energy-saving features reduce total lifetime
ownership costs compared with conventional UHP projectors.
* Using the Auto Light Dimming feature enabled. Actual hours may vary
depending on usage environment.
Energy-efficient Functions
• Auto Dimming Mode
The VPL-FHZ55 is equipped with a light source dimming
function. After 10 seconds of a static signal feed, the
light source dims by approximately 15% which is barely
noticeable. If the VPL-FHZ55 is left powered on while not in
use, after a set period of time it will automatically detect
no change of signal input and will dim the light source
to as low as approximately 5% of original brightness to
significantly reduce energy consumption.

• Auto Light Source Control for Energy Saving
The brightness of the light source's output is automatically
adjusted depending on the brightness of the projected
image, to avoid unnecessary power consumption.
When showing darker images that don't require high
brightness, the light source output decreases.

• Blank (Picture Muting)
With the VPL-FHZ55 one can easily and quickly cut off and
cut on the projected image with one touch of a button. With
this function the screen can be totally blanked with no light
on the screen. This enables the projector to save power and
improve over all presentation experience.

Low Power Consumption with No Input
The VPL-FHZ55 automatically detects no signal input and dims
the light source to as low as approximately 0% of original
brightness to significantly reduce energy consumption.
