Projector lamp failure is most often due to failure with the bulb such as cracking or worse, the bulb exploding. Replacement lamps are more commonly found on the market, but naked projector bulbs are also available. Since upkeep with the lamp and bulb are necessary for producing the best image quality (not to mention safety), it is important to have these parts periodically checked and replaced. This guide shows how to properly replace the projector's bulb.
