One lab that I worked with many years ago came up with an elegant solution to Hg and metal halide bulbs being left on. After having to replace two or three bulbs that burned out early because someone left them on over the weekend the PI went out and bought mechanical light timers and set them up to kill the power to the Hg bulb's igniter/PS at 6:00pm this insured that if the last user of the day left the lamp on it would go off automatically. He left off the tabs that would have turned the power back on so you would have to manually turn power on each day. This move dramatically extended the life of their bulbs. I imagine that it also reduced their power usage, but that was not something being considered at the time.
