    When I say "lamplife" I'm not refering to a type of individual who hangs around lamps! No I'm talking about the life expectancy of PJ lamps. The reason I raise this is I've just seen the spec on the Sim2 HT 300XTRA. 8000hrs! Blimey is this the longest of them all.
    I know Philips raised the bar several years ago with a range of 6000hr lamps(Sim use these I beleive) I also realise that the 6000 hrs is a tad optimistic. But 8000hrs! Is this the longest expectancy of them all?

    Well if they got 9500 from a specd 6000 hrs that would give an 8000hrs a potential 14249 hrs!
    That equates to 91 hrs per week or 7hrs a day for 3 years.

    With the lamp costing £360.00. Thats .02p per hr.

    I could well be wrong.

    if the pj is run for long periods of time, then the lamp might last longer than if its used for tv viewing, constant switching on and off.

    It's the stress on the lamp when warming up and cooling down that shortens lamp life.
    One of my customers has a 3 chip Seleco 1300 Dlp which had a 1500 hr lamp life. He would leave it on all evening if he thought he would watch the PJ again that night. He got over 4000 hours out of that first lamp.
    So don't keep swiching that PJ on and off a lot thinking you are saving lamp life because you are probably not.
