An overhead projector works on the same principle as a slide projector, in which a focusing lens projects light from an illuminated slide onto a projection screen where a real image is formed. However some differences are necessitated by the much larger size of the transparencies used (generally the size of a printed page), and the requirement ...

[1] These were originally known as ultra-high-pressure lamps, [2] [3] because the internal pressure can rise to as much as 200 atmospheres when the lamp reaches its operating temperature.
These lamps use a bi-pin connector for power: 12-volt MR11 bulbs usually use a GU4 base, and 12-volt MR16 bulbs usually use a GU5.3 base. The common 12-volt MR16 lamps, therefore, require a ferromagnetic or electronic transformer —sometimes misnamed as a ballast —to convert the 120- or 230-volt mains voltage to the extra-low voltage ...
