Old Sylvania 300watt Clear Incandescent Light Bulb

I remember at Plattsburgh State that some of the campus meeting rooms had these massive light fixtures with 300 watt bulbs. Each campus meeting room had two of these bulbs for lighting -- while bright, they sucked down 600 watts per hour, or a kilowatt hour every hour and a half in relatively small rooms. But they were getting a lot of cheap Canadian hydropower on the campus, so replacing these luminaries with modern energy saving fixtures probably wasn't worth the cost.

Three-Phase Power Explained

It is a type of polyphase system, and is the most common method used by electric grids worldwide to transfer power.
