They can turn black or just burn out, or explose or have the filiment break on droping. So there really isn't a "normal" way for a lamp to go.

Mini-Mags use vacuum lamps. What you see is the tungsten from the filament actually depositing on the inside of the bulbs as the lamp ages. This traps heat in the bulb further accelerating failure. The greying also reduces output.
Along comes Xenon lamps. which are the same as vacuum lamps except Xenon gas added under pressure (instead of a vacuum). The gas actually holds the tungsten on the filament, greatly slowing the greying of the bulb. But in the end it will grey too. the amount of Xenon varies greatly from manufacturer to manufacturer. Some put in the bare minimum just to stay honest ... however in this case it does nothing to performance.
Now add Halogen to the high pressure Xenon and you get a HPX lamp (patented by Welch Allyn). This has the benefits of the halogen regenerative cycle which actually redepositis the tungsten on the filament, thus cleaning the bulb during use. The result is a lamp that is brighter, lastes longer and doesn't diminish in output with use.
However, in all cases if the filament breaks the lamp is dead and this can happen regardless of the lamp chemistry!
