Nec NP39LP Original replacement lamp for P502H, P502W

Lamp life:
The lamp life is specified by the manufacturer once in normal mode and once in eco mode. Depending on which mode the projector is used in, the lamp may last less or longer. However, the lamp life also depends on the duration of use. The longer a projector is in operation, the sooner it can lose its service life. Furthermore, external influences such as dust or nicotine can lead to a reduction in the service life. In order to ensure a longer lamp life, appropriate maintenance of the unit is necessary. Maintenance means that the air filter of LCD projectors should be vacuumed out frequently or replaced completely if there is a corresponding build-up of dirt. The exact service life of a projector cannot be determined exactly because of this. In order to accommodate the user, the various manufacturers offer different lamp warranty conditions for their devices. For example, one year on the lamp or up to 1000 lamp hours, whichever comes first. However, this varies from manufacturer to manufacturer and can be found in the specific data sheets.
