    I purchased a new MacBook White in december. I was just wondering if my backlight was LED.

    I wonder how much it will dim over the next couple of years and if keeping it turned down will make it's ability to go bright, when needed last longer. I sometimes turn it up all the way to illuminate the keyboard when typing in low light.

    TY for any feedback.

    On full brightness, the CCFL will degrade to half of its intended brightness after 10,000-20,000 hours of use, depending on the quality of the CCFL. So it's safe to say that on full brightness, you'll probably get at least 15,000 hours (625 days of constantly being on)... I wouldn't worry about it. By the time it degrades, you will have already bought a new laptop.

    My old white MB screen dimmed considerably after 13 months of use, i for one am relieved that Apple have used the far brighter and long life LED backlighting for the new unibody MB's.......
