The oem bulb subsequently caused over 1500 worth of damage to the projector as we needed to replace the ballast as well as the lamp.

What is a projector lamp ballast. An electrical ballast is a device placed in series with a load to limit the amount of current in an electrical circuit. There can be two reasons for lamp replacement. Let s assume that you own a projector that says that its lamp is to be replaced. A wide variety of projector lamp ballast options are available to you such as active without.

Over time a fault develops in the ballast where it cannot properly hold the current once the mercury vapor in the lamp has ignited after a high voltage strike. However the projector does have an achilles heel. These are the real reasons and of course one has to put some light source instead of the one that got damaged. With 60 days replacement guarantee.

A familiar and widely used example is the inductive ballast used in fluorescent lamps to limit the current through the tube which would otherwise rise to a destructive level due to the negative differential resistance of the tube s voltage current characteristic. Once the lamp is lit and the circuit has been established the ballast shifts the electrical current to a running voltage. Projector problem 5 projector on but no image if you can get your projector to turn on but then get no image make sure that the cables that you are connecting with are connected correctly. 1 the lamp really doesn t work because the electrodes are damaged or there was a leak and the gas inside the lamp has mixed with air or the lamp has blown.

Ballast a device required by electric discharge light sources such as fluorescent or hid lamps to regulate voltage and current supplied to the lamp during start and throughout operation. If this is all ok then it most likely you have a problem with your lamp ballast unit or the lamp itself. Projector bulbs function by igniting ultra high. Optanium high efficiency instant start electronic fluorescent ballasts for t8 lamps engineered to optimize lighting performance and maximize energy savings optanium ballasts fully support the wide variety of t8 fluorescent lamps on the market.

As the lamp ages with use increasing levels of stress are placed on the ballast lamp driver every time the projector is turned on. Ballast factor bf the ratio of the light output of a fluorescent lamp or lamps operated on a ballast to the light output of the lamp s operated on a standard reference ballast. Projector lamp clinic is an importer and national distributor of 26 brands of projector lamps and spare parts like lamps main board color wheel dmd chip lamp ballast power supply prism glass polorizer glass lcd panel focus lens dmd pcb etc. Each projector lamp contains a ballast system that ignites the lamp with a higher voltage in the ignition phase.
