For all you techies out there, the technical description of a projector lamp is that it is an ultra-high pressure mercury vapor ARC lamp. Projector lamps are scientifically categorized as metal halide lamps and Philips has trademarked the name “UHP lamp” for their projector lamps.
What are projector lamps made of?
There are several components including the ARC tube, ultra-high pressurized mercury vapor, electrical wiring, a quartz globe or reflector, a fastener, a spoke, a bolt, a screw and finally the black plastic housing itself.
How does a projector lamp work?
A projector lamp operates by sending an electrical current across an ARC gap that is full of ultra-high pressurized mercury vapor. The electricity lights the mercury vapor which then causes the lamp to emit a light with an extreme intensity or brightness. The bright light created by this process shines onto an LCD Liquid Crystal Display or DLP panel which then in turn produces the fantastic images projectors are known for. Interesting technology, eh?

Everyone knows that tea is a very healthy beverage. What most people aren’t aware of is that tea is the second most consumed liquid on the face of the earth after water. While Europe drinks higher amounts of tea than the United States does, we’re quickly catching up. Ditch the coffee guys and grab a nice hot mug full of tea! I love a great mug of tea. Usually in the am, sometimes in the evening, and sometimes during the day. There is a simplistic pleasure to brewing a tea. Don’t like it hot?, cool it and have a refreshing iced tea.
