This is more of an issue if you are printing colour Mark. The light output reduces gradually over the lamp life, just as the colour changes slightly. The only time you may notice this is when you replace the lamp with new, but it's not a big issue unless you happen to be in the middle of a print run when the lamp blows. It is certainly good practice to keep a couple of spare lamps ready.
