When to replace the lamp unit
J
The lamp unit is a consumable component. Brightness decreases according to duration of usage, so periodical
replacement of the lamp unit is necessary. The estimated duration before replacement is 4 500 hours for PT-
LX300U and 5 000 hours for PT-LX270U. However, this may be shortened depending on individual lamp
characteristics, usage conditions, and the installation environment. Therefore, it is strongly recommended that
a replacement lamp unit be prepared.
When the projection lamp of the projector reaches its end of life, the warning message appears on the screen.
Replace the lamp with a new one promptly.

(

page 42). For PT-LX300U, Lamp use time = [Lamp used time (Normal)] + [Lamp used time (ECO)] × 0.75
For PT-LX270U, Lamp use time = [Lamp used time (Normal)] + [Lamp used time (ECO)] × 0.833
The usage period of 4 500 hours / 5 000 hours is a rough estimate and is not guaranteed.
