Do light bulbs burn out after a given number of hours or is it the average number of hours?

Assuming conditions are the same should a light bulb burn out the same every time?

    Its really sad to say but its the average. They can actually make a light bulb that will last 10 years or longer, they actually have one that has been burning for over 100 years. Pretty much they just used a really big tungsten wire unlike the so paper thin strips now you need a magnifying glass even to see the filament. What better way to make money than to sell something that wont last very long so you can re-sell more and more of the same stuff that wont last. I think someone needs to open up his own light bulb manufacturing plant and make the light bulbs like they need to be made so they will last 10 years. Even if they cost 20 bucks a pop it would still be cheap to buy those in the long run than to constantly keep replacing the same ole bulbs arggggg.

    It is just an average. Mftrs don't put that much quality control into such a cheap product.
