Lamps (not bulbs)
We’re at a point now, however, where there have been some compromises as well as some
ingenious solutions. And they didn’t come from the lamp manufacturers, either. No, the projector
manufacturers got smart and have come up with:
• Color temperature menus: these allow you to pick a Normal, High Bright and “Cinema”
mode. Really, these allow for normal (no changes), High Bright (blue-ish but maximum
white levels) and “Cinema” (where the brightness is decreased, the black levels dropped
and the color saturation (particularly red) is increased.) It’s artificial, but it can work pretty
well.
• “Eco” mode – sometimes called “lamp saver” mode: By reducing the power supply’s
draw, the lamp is effectively reduced to between 60%-70% of max brightness, but you
usually get a lamp life increase of nearly 50%.
• Dual and Quad lamp assemblies: Some manufacturers are getting really bright projectors
because they’re using between two and four lamps in combination. The flipside of this is
that by using half of the lamps, you can double the lamp life (you really only use half at a
time). At least one manufacturer, Barco, has a projector that keeps track of the hours
used per lamp and will use the lamp that has the least hours on it, alternating throughout
the life of the lamps.
As to the price of the lamps, well, you’re really out of luck there. You will spend between $375
and (on the 10,000 lumen projectors) up to $5,000. As an average, though, the vast majority
of lamps will cost $500. It’s that old supply-and-demand thing.
As a side note, Philips had a lamp factory burn to the ground a couple of years ago and it
caused a real shortage for several manufacturers’ products. Ushio, in particular, really
stepped up their production and broadened their lamp “family” to become the second largest
lamp manufacturer in the world (behind GE, and that includes light bulbs, too). The lesson
here is to stock up on at least one spare lamp for every two projectors you own (assuming
identical projectors).
Finally, please, please don’t call them bulbs. They’re lamps. Really. Lamps.
