Why do all my UHP/similar projector lamps have a recommended (and quite often device-enforced) lifespan of 1500~4000 hours, then? Conspiracy, or is Philips just badly stretching the truth? 10k hours is a long time for any kind of incandescent bulb to last, TBH, and particularly for high intensity flavours like these... Mind you for £200+ you'd expect a little more longevity than what a cheap GU10 or GLS can muster!

Dear commentor of above statement, |
|||
the 10.000 hrs in the article refers to the application of rear television. |
|||
The benchmarking done on these application show that these lifetimes are reached . |
|||
The application of projectors ask a different brightness level and often require high power UHP lamps > 200 W. |
|||
The common brightness level in which a projector is used allow life time today for up to 6000 hrs, but depends on the interaction between lamp and projector set. |
|||
So life time of 10 k hrs can be claimed but indeed relates to the application in which it is used. |
|||

Revision as of 14:18, 20 September 2011
I just made this page after reading about the lamp in my DLP projector, seeing there wasn't one. I'll try to fill it in later with more information from the cited article.Senatorpjt 11:38, 15 May 2007 (UTC)
10,000 hours?
