    Can someone just clarify please....am I right in thinking having the Iris opened or closed is simply a mechanical function on the HS20 which will NOT effect or prolong Lamp life ?

    I've got mine on LOW lamp and Iris ON at the moment but I guess it's just the low lamp bit that will prolong the lamp life ? :confused:

    Only the lamp "power" will effect the bulb life.
    The Iris just "stops" down the light output, and will not effect the bulb life. :smashin:

    Very theoretically, the amount of light absorbed by the iris could cause a slightly higher temperature of the projector, and as a result shorten the life of the panels or the lamp. But other factors are much more important as to preserving lamp life: Not switching on before lamp has cooled down, sufficient airflow and so on.
