They entire bulb doesn't dissipate any more heat energy than standard ones (or at least not a significant amount), but the filament itself runs at a higher temperature - it's the only way you can get more light out of an incandescent lamp (and improve the colour temperature at the same time).
I've used Nighbreakers in my car for the last few years; personaly I've not yet actualy had one fail but the light output does degrade as they age. I know other people that have head them fail after only a year or so.
