Projector Lamp Advice For US Consumers
|
Refurbishment Dangers
Please note that Projector Lamp Experts has taken the decision to exclude any type of lamp refurbishment/re-bulbing from the services it offers to its customers. This includes the sale of "bare bulbs" without housing. After serious concerns have been raised over the safety and quality of lamps that have been re-bulbed we feel it would be unprofessional to put the safety of our customers and their equipment at risk. The safety reasons for our decision are outlined below. Since projector manufacturers generally do not intend their lamps to be sold without plastic housing, the authenticity of ANY projector lamp (with or without housing) sold by a company offering lamps without housing can be questioned. Always make sure to ask if the lamp your are getting is a manufacturer original lamp or not.

Warranty concerns
The constituent parts of a projector lamp module are assembled by the manufacturer in a highly precise process and are not designed to be taken apart and refurbished with a third party lamp. Often after a module has been taken apart even trained professionals may find it difficult to re-assemble the module. Putting a refurbished lamp in your projector may void its warranty and lead to reduced performance.

Mercury dangers
Projector lamps contain mercury gas, which, if the lamp is damaged during a bulb replacement, can escape. Mercury has been found on the plastic housing of lamps that have had their bulbs replaced, which poses an obvious and serious health risk.

Used products may result in reduced performance
During operation the entire lamp module is exposed to extreme temperatures, so replacing only the bulb leaves the customer with a used product that will give reduced performance compared to a brand new lamp. The wear-and-tear of connectors (a component of the plastic housing) can influence the stability of the lamp's electrical supply, resulting in a flickering image.

Dust build up
Dust particles build up around the bulb and module during a lamp's life which are difficult to remove 100% successfully, even by experienced engineers. The dust particles retain extra heat within the housing as well as disrupting air-flow which cools the lamp. Both of these elements shorten lamp life and can cause the projector to overheat or malfunction.
