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 w\
arning message appears on the screen. 
Replace the lamp with a new one promptly.
Model nameLamp runtime
On screen:Warning Lamp message
PT-LX300UOver 4 470 hours *If the lamp is used over 4 470 hours, the warning message will 
appear. When any button is pressed, the message will disappear. 
PT-LX270UOver 4 970 hours *If the lamp is used over 4 970 hours, the warning message will 
appear. When any button is pressed, the message will disappear. 
Note
The lamp replace time, it is necessary to carry the following calculation. Confirm the lamp used time in the [LAMP  settings]  z
(Æpage 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. z
