Dual Lamps

Dual lamps enable a level of reliability simply unavailable with

a single lamp projector. Both lamps can be used together to achieve

maximum brightness, while still providing redundancy should one of

the lamps fail. Alternatively a single lamp can be used in Relay Mode to

combine the full lifetime of each individual lamp and thereby minimize

service intervals.

Lamp Relay mode

For challenging installations where the EH7700 is run for long periods,

the Lamp Relay function can be used to automatically switch between

lamps.

DLP

Technology

DLP

technology from Texas Instruments

is widely recognized

and acclaimed for its unmatched reliability and long lasting image

performance. When combined with high brightness and native

contrast ratios, it becomes the obvious choice for demanding

applications. Independent testing has proven DLP

to be the most

reliable of projector technologies. While other technologies may

show image quality decline after only a few thousand hours, DLP

technology can remain unchanged over hundreds of thousands

of hours.

Total Cost of Ownership

For demanding applications the total cost of ownership

of a projector is not in the purchase cost and replacement lamps

but in expensive maintenance and service. Optoma ProScene

projectors require very little maintenance, have no user serviceable

parts inside and no filters that require periodic replacement. The

result is low cost, predictable service cycles, enabling planned

down time to be minimized.

All Optoma ProScene projectors are designed for continuous 24/7 operation. Only the most reliable, industry

proven components are used to ensure superior reliability. This hard-earned “capability” has been meticulously

developed over a decade of designing, manufacturing, and supporting millions of projectors the world over.

the most reliable projector brands in the industry today, Optoma has a reputation for service excellence that is well deserved.
