Assume that each workstation is lit by 100W of lighting and is vacant 18 hours per day (to make the math easy).

I claim that's 75W of power that could be reclaimed by turning off a 100W load 75% of the time. Explain how you get to energy or how I dropped time, please.

2400 watt hours in a day, being reduced to 600 watt hours.

If you're not going to be charitable in interpreting comments, then perhaps this isn't the venue for you.

		Uh... Watt-hours per day reduces to Watts in dimensional analysis, which is of course my original point.
