    As you can see from my recent post I'm new to the whole HDTV hobby. I was wondering if anyone could tell me how long the bulbs are going to last on the Hitachi 55" DLP. It says that the bulbs are $200 and I was wondering if this is high? How many need to be replaced? One of them or all three? I'm also looking at the Panasonic PT-50LC13 50-IN WIDESCREEN. How long will the bulb last in this screen? It has LCD technology so I'm not sure if that makes a difference on longevity of the bulbs or not? Thanks for any help with this.

    LCD and DLP TV sets have just one bulb (projection lamp).

    Normally the kind of technology has nothing to do with the life of the bulb.

    Some sets have a color temperature setting that depends on the brightness of the bulb. For these sets, choosing the low brightness gives a longer bulb life.

    Turning the set off and on frequently shortens the life of the bulb but there is still an average operating life in hours. There are no scientific formulas published and it varies from one brand to another, but I would guess that if you are going to come back within two hours, leave the TV on.
