When to replace the ET-LAD40W Lamp unit

The lamp units are consumable parts. The lamp brightness decreases gradually as the cumulative operating

time increases, so periodic replacement is necessary. The replacement guideline is 3 000 hours, although the

lamp may become dead (will not light) before 3 000 hours is reached depending on the characteristics of

individual lamps and other factors such as the operating conditions and the installation environment. Therefore,

it is recommended for the user to keep a spare lamp unit.

The risk of the lamp bursting increases after 3 000 hours of operation, so the lamp unit turns off automatically.
