Viewsonic PJD5123 DLP Projector Review
The Viewsonic PJD5123 is an entry-level DLP projector that's bright enough to satisfy most demands.
You can expect it to raise the ambient noise of the room by between 9 and 10 decibels in Brightest mode. It's a little bit louder when Eco is on.
Projectors generate two things in copious amounts: light and heat. In Brightest mode, the fan kicked out air that was 76.2 degrees (F) higher than the temperature of the room. When Eco was turned on, it only raised the temperature by 67.8˚.
Power consumption was relatively inexpensive for a projector, but these are still somewhat costly to maintain. If you use it for five hours a day, you'll spend between $40 and $45 a year on electricity. But what will you gain in presentation knowledge?
The lamp in the Viewsonic PJD5123 is a RLC-072. It promises to last 5000 or 6000 hours, depending on whether you keep it in normal or Eco mode. The current run-time is recorded in the menu, so you can keep tabs on how long it's got to live.
