    I would believe having your backlit keyboard on max would kill the life span of the led lights? curious to know if anyone has it on max majority of the time to have the laptop look fancier ;) rather then those who use the backlit accordingly to prolong its life time.

    But in the cases for those who do set the backlit keyboard on max for a long time (speaking of months, even years) any issues with it? any led lights or keys breaking or stopped working?

    I haven't ever seen a keyboard backlight go out on a Mac. I really think you're worrying too much. Keep it as bright or dim as you want and chill.

    Seriously.


    I've never heard of one complaint on this.

    LEDs typically last around 100,000 hours, or 11.4 years at max brightness 24/7.

    Did you bother to look into what the normal lifetime of LEDs is?

    From the Wikipedia article:
    http://en.wikipedia.org/wiki/Light-emitting_diode
    Many of the LEDs produced in the 1970s and 1980s are still in service today. Typical lifetimes quoted are 25,000 to 100,000 hours but heat and current settings can extend or shorten this time significantly.​

    Unless you've done a hardware mod and are overdriving the LEDs beyond their max current rating, I think something else will kill your computer long before the LEDs burn out.

    lmao things like this are things PC users like myself used to worry over. Me being new to apple with my 1st ever mbp, just thought i'd ask the question, but now im realizing more and more that the premium purchase for one of these things are well worth it =]

    ? Apple uses the same LEDs as everyone else (it´s not like they´re premium GaN or anything)

    White leds have shorter lifetimes than the coloured leds *but* still typical led lifetimes are >30000hrs, before output is signifcantly reduced - that´s a lot of time in service

    LOL. So true. I absolutely love my Apple products. I just wish Apple gave us more BTO options. At the end of the day, they're so well made and have such a great design that there's nothing that truly competes with them. We are lucky to have Apple building Mac computers and we pay dearly for them.

    So use it as the backlit keyboard is meant to be used at any normal setting.

    Congrats on joining the club. Be prepared to fall in love.

    Enjoy!

    since we are on longevity of backlighting....what about the laptop's display? when does it start losing its brightness/colors?

    I have a 4 year old MBP that was used every single day with the back lighting turned on to max brightness with Labtick (because the ambient light sensor failed first! lol) and the back lighting still looks like the day it was purchased.

    It's even had 2 drinks spilled on it.

    Well, the light on my PowerBook G4s keyboard broke a little over a year of ownership – just outside of warranty. I guess there are other things that could be wrong apart from the leds itself.

    Dear op, there is no need to stop worrying. Your new mac will have its own little quirks sooner or later. ;)
