Calculations of lamp life
achievement taken from this
graph should be considered
strictly theoretical as the life
factor is considerably
influenced by frequency of
switching, environment,
vibration, handling, cleaning
etc. This graph is based on
the average achievement of
numerous lamp tests, and
thus should only be used as
an approximate guide to
performance.
