Dell 7609WU Projector - Manual (Page 52)

Specifications 52
NOTE: The actual operating life span of a projector lamp will vary according to
operating conditions and usage patterns. Usage of a projector in stressful
conditions which may include dusty environments, under high temperatures
and abrupt powering-off may result in a lamp's shortened operating life span or
possibly lamp failure. The lamp life specified for Dell's projectors refers to the
typical time under non-stressful operating conditions for more than 50% of a
sampling population to reduce to approximately 50% of the lamp's rated
brightness level. It is not the measure of time a lamp will cease light output.
