Projector Lamp Relamping

Maestro Lamps does NOT re-lamp projector lamps. Projector lamp re-lamping is NOT recommended / encouraged by Maestro Lamps or by any audio/ visual professionals.

There are several risks 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.

Maestro Lamps has found that refurbished lamps do not meet acceptable standards for their customers and have dangerous implications. Most projector lamp housings are not designed to allow easy access to the bare bulb and often have to be broken open during replacement, which is then difficult to fit properly into the projector and becomes a fire risk. Connectors also become worn after use, dust particles build up on the housing causing excessive heat and the overall performance of the lamp is diminished.

What is Re-lamping?

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

Projector lamps contain mercury which is very poisonous. When refurbishing lamps there is a risk that mercury chemicals may escape and be left on the old housing. This is a potential health hazard to those who carry out the refurbishment and to the users of refurbished lamps.

The Re-Lamping process requires the bulb to be physically forced out of its housing and this often results in the bulb being broken. This risk of spilling mercury from the bulb is very dangerous. Mercury is highly poisonous and can cause serious health problems to those who come into contact with it.

As the connectors in a Re-Lamped lamp are old and have been used time and time again, these can become less effective and often fray.

This can cause the connectors to twist together or overlap and could lead to short circuiting the lamp and projector, an obvious and massive electrical hazard.

Connectors also become worn after use and depreciate in quality over time. This can influence the stability of electrical supply resulting in image flickering or even damaging the projector.

In order to remove the bare bulb, the lamp module has to be taken apart, something which manufacturers have not planned for and therefore not made an easy task. Most projector lamp housings are not designed to allow easy access to the bare bulb and often have to be broken open during replacement. If the housing has to be broken it can be difficult to rebuild the plastic (often impossible to get it back to its original condition). This means the lamp module often will not fit correctly into the projector and can cause improper focusing as well as a fire risk.

Across a projector dust particles Left in the Module Housing or lamps life dust particles can build-up around the bulb and module. These dust particles have proved to be very difficult to remove 100% successfully, even if you are an experienced engineer. The dust particles retain extra heat within the housing as well as disrupting air-flow that cools the lamp. Both of these elements shorten lamp life and can cause the projector to overheat or malfunction. A fire hazard can result.
