It’s common to log onto Amazon and be unable to find your projector replacement bulb. Worse yet, a particularly popular model that was discontinued may in fact be wildly expensive to repair. If you plan on keeping this around and used regularly, pick up one or two replacement bulbs. It’ll also make the moment your bulb burns out a lot less painful.
