What does a projector lamp cost ? If you
think the cost of a projector lamp is comparable to a standard 60-watt
light bulb, think again. Projector lamps are relatively expensive,
ranging from 200 Euro for low lumen projectors, to over 600 Euro for
high lumen projectors. The average projector lamp cost is 350 Euro.
There are good reasons that the price is what it is.
LCD projector lamps (also called LCD
projector bulbs, LCD projector modules, data projector bulbs, data
projector modules, or video projector bulbs) are highly specialized
lamps with a high cost of production and development.
Many things contribute to the high
cost of projector lamps, in this particular case, Manufacturers invested
hundreds of millions in the development of the UHP lamp and, of course,
they want a return.
UHP Projector lamps are made of
borosilicate glass and fused quartz. Quartz is hard as a rock at the
melting point of iron (1535 degrees C). Steel tools melt before quartz
gets workable. And you need torches using oxygen to get hot enough - a
regular Bunsen burner or even a "MAPP" gas blowtorch from a hardware
store is not hot enough.
And if you have the heat and the
tools, there is still another problem - quartz has a narrow plastic
range of temperature. The temperature needed to get quartz barely as
soft as taffy or frozen chewing gum is only a few dozen degrees short of
making quartz liquid enough to pour. Quartz is trickier to work than
glass and glassblowers that can work quartz will not be working for
minimum wage!
Although we are in a world of
mass-production, many steps of the UHP Lamp manufacturing process still
are hand-made by a skilled craftsmen and will cost many times the cost
of a mass-produced lamp.
Production machinery that can
mass-produce quartz lamps is so expensive that only lamps that will sell
in huge quantities (hundreds of thousands) can be made economically by
such machinery. Otherwise it would cost even more to get the machines
made and set up than it would be to hire those highly skilled
glassblowers.
If you have a specialty ARC lamp
design that would use the same bulb and the same leads as a lamp that is
in mass-production, then maybe you could make a deal with an existing
lamp manufacturer. (Expect a minimum production run of thousands -
perhaps many thousands - of lamps at a price at least a few times that
of a mass-production lamp in order to make it worthwhile to the
manufacturer.)
