If you decrease bulb temps the filament doesn't last anywhere near as long. The hot filament makes it possible for particulate matter to condense back on the bulb. If its not hot enough the particulates won't melt fast enough, they will just precipitate to the bottom of the bulb.

Its the idea behind HID lights. They fail at low voltage very quickly
