Replacement lamp unit model No.: ET-LAD35 (single bulb) Rating: 300 W
Long-life lamp unit model No.: ET-LAD35L (single bulb) Rating: 160 W
Other lamps than specified above cannot be used. Be sure to use the specified lamp.

REPLACEMENT
Wait until the lamp is cooled sufficiently before replacing the lamp unit.
The lamp used for the light source has its due life. The life of light source lamp used in the main unit is 1500 hours
*1 (when lamp output is HIGH). However, it may happen that the lamp becomes dead (will not light) by the time of 1500 hours *1 depending on the characteristics of individual lamps and working conditions (lamps may reduce their life affected by the times of lighting and the intervals between previous lighting and next lighting). Therefore, it is strongly recommended for the user to keep a spare bulb. If your lamp unit is not replaced after 1300 hours *2 (with the lamp output set at “HIGH”), power supply will be turned off automatically at the time of 1 500 hours *1 entering a standby state. After 1500 hours *1 of initial lighting, power supply is turned off automatically about 10 minutes later, entering a standby state even if it is turned on again.
