One of the answers to your question states that since this is an LCD projector, you won't have to worry about bulb burnouts. This is incorrect. The LCD is NOT the light source, it is the panel which produces the image, with a source of light required BEHIND the LCD panel to project the LCD image. That light source could be a traditional bulb (subject to burnouts) or an LED light source. Which one of the two will vary from one projector to another. I suspect the person who wrote the incorrect answer confused LCD (the imaging panel, which requires a light source) with LED (a light source).
