3.8.7 When to Replace the Lamp
Assuming the Lamp Expiry Message checkbox has been enabled in the
Advanced: Preferences
menu
(recommended), an expiry message will appear on the TPC (as an alarm window) when the lamp has reached
its defined Lamp Limit and should be replaced.
Lamps should also be replaced when one of the following events occur:
• Lamps are no longer able to maintain SMPTE specified light levels
• Image quality is compromised by excessive flicker
• Lamp hours have exceeded expected average life
Regardless of the Lamp Limit chosen, never exceed the lamp lifetime by the hours shown in
Table 3.24
, as an
old lamp becomes increasingly fragile and more prone to sudden failure or even explosion, which can be
damaging and dangerous.
Table 3.24 When to Replace Your Lamp
NOTE:
Hours shown here are
greater than or equal to
the pro-rated credit warrantied lifetimes (refer to
Section 8 Specifications
).
Do not exceed.
Refer to
Section 6.4 Replacing the Lamp & Filter
for instructions.
3.8.8 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 by the TPC. It is a good idea to periodically recalibrate
footlamberts (refer back to
Figure 3-36
).
