How long should a projector bulb last?





If you read a spec sheet, most brands claim their bulbs have an average life of 2000 hours. Ever wonder why your bulbs never last that long?

The average life span assumes the projector is being used in a dust-free / climate controlled environment (yours isn’t) and is turned on once, never turned off, and running in a 24/7 application for 2000 hours (again, yours isn’t used this way).

Bottom line, you can usually count on getting about 1000 hours of life from your projector bulb.

Check your actual hours (your mathematic guestimate doesn’t usually work) in the menu of your unit. Don’t go into Easter week without a spare if you are at that 1000 hour mark.

  1. Heat is NEC projector lamp NP20LP quality affected by the loss, after the projector is powered off, better let it cool for some time. Because the closed design of the projector is difficult to automatically heat, then unplug the power, the projector fan will immediately stop working, a lot of heat generated in this way for a long time projection lamp work, will accumulate inside the projector, and seriously affect the lamp electrical performance of internal components, the worst case can lead to lamp explosion phenomenon.

  2. They are delicate to movement as well as are breakable. Since they can be damaged conveniently, care should be taken while removaling the projector. lampschoice: http://lampschoice.com/?portfolio=replacement-projector-lamp-holder-fit-for-epson
