For most computer projectors installing a new projector bulb is quite simple. This thing to keep in mind is that the projector bulb housing and glass are very fragile so be very careful when installing a new bulb in your projctor. The most important part of the bulb changing process is that you should never touch the glass housing on the bulb. The oils from your fingers will get left on the bulb and can cause the projector bulb to burn out or even burst. Handle the projector bulb by the metal housing to avoid having to replace this costly bulb again.
