How to extend your lamp life Never touch the bulb with your fingers, always use a cloth for handling.
Installation Any glass components of a lamp should never be handled without gloves; deposits from fingerprints cause temperature 'hot spots'. In the long term, the accompanying temperature gradient stresses the glass resulting in early failure.
Clean the air filters of the projector. Blocked filters make the lamp overheat and fail early. Manufacturers can test for this kind of failure and any warranty becomes invalid. Always ensure that there is good airflow around the projector.
If you are fitting a bulb into an existing module housing, ensure the terminals are not over tightened as the ceramic can be cracked and reduce the electronic insulation of the lamp.
Alternatively, if they are under tightened, it can cause arcing on the terminal which puts undue load on the ballast that can then lead to a failure.
For plug in bulbs, be sure the lamps are seated completely. The tendency is to stop at the first sign of resistance. Continue to apply force at the base of the lamp until you are sure the lamp is secure.
