What's the life expectancy of LCD light bulb?

[watdahel]

I personally have my computer on roughly 15 hours a day every single day because I'm a nerd. There's no way around it. I know for a fact that I have to change the flourescent bulbs in my room every year so I'm thinking it may be the same with flat panels. Are they easily changeable? What's your own experience on this matter? How long do they really last? Let me know before I splurge on an LCD.

I hope you are not looking at it 15 hours a day, because if you are, you probably won't need to worry about when the monitor will go bad, because you will probably be blind long before that !!!!!!!!

If it goes bad, buy a new larger one for about half of the price you paid for the one you are presently using.

I recall this question coming up before and as I remember, the life is 30,000 - 40,000 hours. Aprox. 4 year life span if on 24 hours a day. For most of us it would probably be about 10 years of use. I've never kept a monitor that long!

A lot of people have their computers on 15 hours a day or more, but there's no reason for the monitor to be on if you aren't actually at it. If I'm just going to be around the house and on/off the computer all day, I just let low-power mode go at 15-20 minutes, otherwise if I'm going out for a few hours or more I tend to just shut off the monitor. I really doubt you'd have to worry about the backlight dying. I haven't even heard 1st gen ones dying yet, but just use a little common sense when using it anyway.

Backlights last for a long time. Unfortunately, LCDs are still so new that we don't really know how long they last in practice (i.e. consumers reporting in the aggregate); however, manufacturer specs are I think like 40k hours or 60k hours or so.

I think it really depends on the model and quality of the bulb. Where I work we buy all Gateway stuff.
We have about 250 Gateway 1830FP's that are almost 3 years old. Just about a month ago the back lights started dropping like flies.
Seems like 2-3 of these monitors or going bad per week now. The odd part is we also have an earlier model on the floor called the 1810 that we have had for over 3 years and we have never had back light issues.

So I think it all depends on the diferent quality backlights they put out and whos to know which ones will be better?
