End of projector lamp warnings

It’s time for a new Dell 3100MP projector lamp when this message appears on screen: Lamp may fail soon! Replacement suggested!  Just before the projector lamp reaches end of life you may notice a change in color on the screen or a distorted picture.  Don’t wait to change the projector or it may explode from over use.

The importance of authentic lamps

The Dell 3100MP projector needs an OEM Dell 310-1705 projector lamp to keep working at its best. While counterfeits are tempting due to their bargain prices, they can’t be calibrated properly so they can damage the sensitive optics in your Dell 3100MP projector. They also have much shorter life due to their tendency to explode and present a health hazard. Save yourself hassles and purchase an authentic projector lamp! Look for the seal of approval before purchasing.
