    well w/ the MBP and the LED backlit, i can say.. the backlight is POWERFUL

    i put it at around 60% well.. considering tha tmy room is pretty dark, the full display seriously feels like a flashlight...

    What do you mean? Like, the screen won't be as bright in 4 years as it was the day you first bought it?

    yeah exactly that

    oh and may i add, "if so, how long will it take for it to lose its power"

    The LED can lose some brightness, but it's much less than the older displays did. In those you would see it much dimmer after a year. On a 17" LED I have after 8 months there is no noticeable difference in the display brightness.

    would i be safe w/ using full brightness a lot?
    or would it better for me to 'prolong' the life by going a little dimmer?

    They're designed to be used at full brightness. LED will loose a small bit of power over time but nothing like the old displays. So don't worry

    I'm using right now one of those old, bad LCDs that supposedly had so short a lifespan. It's only 10 year old (!) and I don't know about the brightness (impossible to notice the difference during so long a time), but it doesn't seem dim. Granted, it's rather small and has lower resolution than a MacBook, but it works. I think people worry too much about longevity of these things; I don't know any statistics, but it seems they're more likely to fail because of random reasons rather than die while you're still using them.

    LEDs lose power very slowly.

    Of course, even fluorescent-backlit LCDs deteriorate far less easily than CRTs do.
