As a leading projector replacement lamp module expert, APO’s experience has indicated the danger of re-lamping process and its potential risk, which brings the current re-lamping service hazardous to both its re-lamping staff as well as customers.

APO admits the fact of removing a used bulb and replacing it with a new one, keeping the old lamp module, old housing and old connectors, the cost of the lamp is less expensive for the reseller and the process is more environmentally friendly than replacing the entire lamp.

The initial reasons behind the service have since been overridden by the severe damage caused to the lamps. APO’s Managing Director, Samuel Chen explained:
"Projector lamps contain mercury which is very poisonous if released from the bulb. During the process of Re-Lamping, we found that mercury could escape and be left on the old housing which is a potential health hazard to those who carry out the refurbishment and to the users of the lamps. We simply wouldn’t want to put the health and safety of our staff or customers at risk so we’ve decided to terminate this service at once."

APO 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.

Samuel continued:
"It is the danger risks of Re-Lamping that APO is particularly opposed to, and these combined with the significant impact on the performance of the lamps has led to us re-evaluate the service and deemed it as ethically and morally unacceptable. When there is a greater risk that lamps could overheat and make the lamp explode or the projector malfunction, it is something we do not want to be part of.
"We think that a safer and still very cost effective option instead of Re-Lamping is for resellers to offer Branded Compatible APO lamps to their customers. These are made from new bulbs, modules and connectors which serve as no threat to the end users whatsoever."

Projector Manufacturers are also concerned about the performance and risks or Re-lamps. InFocus UK Sales Manager Stuart Harper Commented:
"I would like it known that InFocus would not recommend the purchase of such units. InFocus Corporation takes pride in the quality of their products and we cannot be sure our projectors would offer a crisp and bright image when used with re-conditioned lamps."

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 projecDust particles Left in the Module Housingtor 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.
