Projector Lamp Advice For UK Consumers

The Risks Involved With Refurbished Projector Lamps
Due to the dangers associated with refurbishing a used projector lamp module, Projector Lamp Experts UK has made the decision to avoid supplying any kind of projector lamp refurbishment service or re-bulbing arrangement for its UK customers. This means that Projector Lamp Experts UK does not supply "bare bulbs" which come without plastic housing around them. Projector Lamp Experts UK has taken the position that it would be not be professional to put the safety of UK consumers and their expensive projector equipment at risk, after serious issues have been brought up about the quality and safety of projector lamps that have been refurbished, also called "re-bulbed".
There are a number of safety reasons why Projector Lamp Experts UK has taken steps to avoid offering projector lamp refurbishing and re-bulbing services. These reasons are summed up in the sections below. Due to the fact that projector manufacturers do not often supply their replacement projector lamps as bare bulbs without plastic projector lamp housing around them, if a company that sells projector lamps offers bare bulbs without projector lamp housing you should be cautious, since the authenticity of any projector lamp that this company sells could be questioned. It is a good idea to always contact the company to ask whether the projector lamp you are about to buy is actually a manufacturer original projector lamp or not.

Warranty concerns over refurbished projector lamp products
The constituent parts of a complete projector lamp module (the projector bulb, the lamp reflectors, the projector connectors and the projector lamp housing or cage) is constructed by the manufacturer of the projector lamp module in a process which is extremely precise. This process is not intended to be reversed, and projector lamps are not designed to be taken apart and refitted with a bare projector lamp that has been manufactured by a third party. What can often happen is that after the projector lamp module has been taken apart to have the bare bulb inserted, even a trained projector lamp specialist can have problems putting the lamp module back together again. It is important to note that putting a projector lamp that has been refurbished with a bare bulb into your projector may void your projector's warranty. It can also result in a reduction in the projector's performance

Refurbished projector lamp mercury gas problems
Projector Lamp Experts UK does not recommend replacing only the bulb in your projector lamp. The projector bulbs inside projector lamps contain mercury halide gases. If the projector bulb is damaged while the projector lamp is being refurbished with another bulb, there is a chance that this gas could be released. Tests have found mercury on the plastic projector lamp housing of projector lamps which have been refurbished, and so refurbishing a projector lamp with a bare bulb could result in unnecessary health risks.

Reduced lamp performance levels from used projector lamp parts
When a projector lamp is in use, the whole projector lamp module is working under an extremely high temperature level. The important point is that it is not simply the bulb that wears down during the projector lamp's life span. If it is just the bulb that is replaced, all the other parts of the projector lamp which are worn during the lamp's operation remain. When compared to a brand new projector lamp module, this partly used projector lamp module will not produce the same high level of performance. One of the key parts of the projector lamp module which is gradually worn during the projector lamp's operation is the lamp's connectors, which are found in the plastic projector lamp housing. This connector wear and tear can also have an adverse effect on how stable the projector lamp's electrical supply is. This can cause the projected image to flicker.

Projector lamp dust particle build up
Dust particles can build up around the projector bulb and module over the operating life of the projector lamp. Even for a trained projector lamp engineer, removing 100% of these dust particles completely can be extremely difficult. The build up of dust particles causes the problem of keeping extra heat inside the projector lamp housing while it is in operation, and the extra dust can hinder the flow of air around the lamp module which is supposed to cool it. Both of these dust related issues can eventually reduce the amount of time that a refurbished projector lamp will last for, and can even cause the projector itself to overheat and malfunction.
