Caring for you lamp and projector properly will help ensure you get the best from them. Always ensure there is good airflow around and through your projector and that it is kept as dirt and dust free as possible. Check air filters regularly and clean or replace where necessary. Using your projectors economy mode, if it has one, should extend lamp life. Before moving your projector ensure that it has been allowed to cool thoroughly.
