Just today I received notice from my projector that it's time to replace the lamp. Does anyone have any idea approximately how many hours I should get before it goes out all the way? I am currently at about 2700 hours after having it for close to two years. I orginally purchased the projector from Projector People and was very happy with their service. Now having said that, they seem to be on the pricey side replacement lamp wise. What's a fair price to pay for a replacement lamp? Does anyone have any suggestions?
