3.6.3 Age of a Lamp

When to Replace a Lamp

When a new lamp is installed and its serial number recorded in the Advanced: Lamp History menu, the lamp
timer resets to "0" and begins logging time for the new lamp. All lamp information is displayed in the
Advanced: Lamp History menu including the last eight lamp logs.
Assuming the lamp Expiry Message checkbox has been enabled in the Advanced: Preference menu
(recommended), an expiry message will appear as an alarm window when the lamp has reached its defined
Lamp Expiry limit and should be replaced.
Regardless of the Lamp Expiry limit chosen, never exceed the warrantied lamp lifetime by more than 20% as
an old lamp becomes increasingly fragile and more prone to sudden failure or even explosion, which can be
damaging and dangerous. These maximum limits appear in the table below:
Table 3.23 Lamp Expiry Hours
Lamp Type
CDXL-20 (2.0 kW)
CDXL-30 (3.0 kW)
CDXL-30SD (3.0 kW)

Lamp Rotation

When the lamp reaches mid-life, a Lamp Rotation message will appear as an alarm window to indicate the
bulb should be physically rotated 180° to ensure an even burn of the lamp. Rotating the lamp improves its
performance and life expectancy.
Lamp rotation requires removal of the quartz bulb and therefore the same safety precautions as lamp
replacement must be taken. Lamp rotation must be performed by qualified service technicians only.
You must acknowledge that lamp rotation has taken place before beginning normal operation again via the web
user interface Advanced: Lamp History menu or CDP Lamp menu.

Maintaining Footlamberts

Over time, as the theatre screen ages and dust and dirt collects on the port window, the theatre may no longer
be achieving the expected footlamberts as reported. It is a good idea to periodically recalibrate footlamberts
(Figure 3-40).
