It helps your tv see better pictures which a normal lcd tv cant do. But to me these lamps are very pointless and just a waste of money by the way tell your mom i said hi.
Projector televisions require lamps which occasionally can burn out. Replacement lamps for many popular models of televisions including Panasonic and Sony can be found online at the DLP Lamps website.
A DLP lamp is used to power what is seen on a rear-projection television, and is also used in modern color digital projectors. Digital cineman projection also used DLP technology.
A Mitsubishi DLP lamp varies in price depending on the model it is required for and prices may be approximately $35-$40 with DLP lamps for different models being available on Amazon.
A DLP lamp may need to be replaced because it may have become faded or have burnt out. DLP lamps are often used in HDTV, LED and LCD televisions for picture quality.
Toshiba DLP lamps are energy costly to have and use, because they have to be replaced fairly often. More information can be found here: http://www.ehow.com/how_7206948_change-lamp-toshiba-dlp-tv.html
There are a variety of sites available to find Toshiba dlp lamps. I liked the site www.bulbsolutions.com If you click price low to high you will find that they start $ 59.99 and you are saving $ 109.00.
DLP technology is based on the properties of mirrors. A special optical semiconductor (DMD - Digital MicroMirror Device) is used in DLP TV sets and contains thousands of tiny aluminum mirrors.
For DLP front and rear projection televisionsusually lamps last between 1000 and 2000 hours.No body cant exactly predict this.So there is such a broad range.It is pretty simple that people need to replace their lamps once in 1-2 years.And easily you will know when to repalce the lamp.The TV screen loses its brightness and appears dim.Then you can simply repalce the lamp.
A DLP is a digital light projection tv. Sometimes it's a projector and sometimes it's a rear projection tv, The advantage lies in the price advantage gained at very large screen sizes. For example a 72 inch DLP TV or projector would cost significantly less than other types. However it can be expensive to replace the lamps, which all have a limited lifetime. You should research the subject carefully before buying one.
DLP stands for Digital Light Processing. For more information on DLP please visit http://tv.about.com/od/projectiontv/a/dlpintroduction.htm. I hope this helps
A local shop that sells projectors and related equipment should have them in stock. You could call around to save driving. You may also be able to find them for sale online.
