Deactivate Half of the Florescent Bulbs in Overhead Lighting

In existing buildings where more than sufficient lighting exists, rotate half of the bulbs in each overhead fixture by 45 degrees to deactivate them. That could save up to 50% of electricity used for overhead lighting with no upfront retrofit investment. Many areas I work in are far too brightly lit. The excess lighting is often visually uncomfortable and a gross waste of energy.
