Projector Lamp Re-lamping

MPLAMPS.CO.UK will NOT re-lamp projector lamps. Projector lamp re-lamping is NOT recommended by MPLAMPS.CO.UK or by any audio/ visual professionals.

Several risks are involved in purchasing a re-lamped bulb, including severely decreased lamp life, LCD panel or image damage due to inconsistent burning temperatures and possible permanent damage to your projector.

What is Re-lamping?

Re-lamping is the replacement of the ARC tube that sits inside a projector lamp's quartz globe. Re-lamping companies will hollow out the ceramic base holding the old burner in place and then place a new burner inside, setting it in place with extra strength caulking.

Why is Re-lamping Dangerous for my Projector?

Low Quality ARC Tubes

The major and globally recognized projector lamp manufacturers are the only companies that make original ARC tubes. However, re-lamping companies often source ARC tubes from knock-off manufacturers who make ARC tubes without proper equipment in China. The equipment required to manufacture high quality ARC tubes for projector lamps costs millions of dollars and millions more per year to maintain and improve.

Chinese manufacturers make projector lamps often using cheap methods that don't utilize the proper equipment. Low quality ARC tubes limit projector lamp life severely, often running less than 200 hours. The harshly diminished lamp life makes the purchase actually more expensive for the customer in the long run. By the time a second lamp is purchased, the customer will have spent more than it costs to purchase one high-quality lamp from MPLAMPS.CO.UK.

Permanent Damage to the Projector

Positioning of the ARC tube angle has to be precise. In the re-lamping process, the burner's angle is almost always done incorrectly because re-lamping companies position ARC tubes manually with simple tools. If the burner angle is off by even a 1000th of an inch, it can cause the projector lamp to burn brighter and hotter in certain spots. In return, this can cause the lamp to burn the LCD panel, causing blue, red, or green sections to appear on the projector's display image. If this happens, it means there's been permanent damage done to the LCD panel. (When purchasing a new lamp from the major manufacturers, multi-million dollar equipment with regular maintenance ensures that the burner angle is to the exact specifications required by the projector).

Mercury Leakage

Finally, a burner set incorrectly can lead to the mercury vapor leaking from the burner itself. Projector lamps operate by igniting ultra-high pressurized mercury vapor across an ARC gap. When you purchase a re-lamped projector lamp, essentially there is a low quality burner placed inside a reused quartz globe. This practice does not adhere to strict safety regulations that are in place by government agencies and which major manufacturers must follow. These measures ensure that when a lamp is purchased from one of the major manufacturers, they will not leak; however, with a re-lamped projector lamp, mercury leakage could occur. This is what causes faded lamp brightness and lamp life to be shortened. Keep in mind, mercury is extremely harmful to your health, and can permanently damage the equipment inside the projector.
