Lamp Hours
The combined number of hours used by every lamp ever installed on the projector.
If the projector has had 2 lamps replaced, each with 100 hours usage, and the currently
installed lamp has 50 hours of usage then the cumulative total will be 250 hours.
When a lamp is replaced the usage of the previously-installed lamp is zeroed out by a nega-
tive value equivalent to the total number of hours used by the previous (replaced) lamp being
written into the parameter history table (tblDeviceParameterValues). The reports take this into
consideration and ignore negative delta values in summations.
