I had a strange situation today, my company sent in one of it's Infocus LP-350 projectors for a lamp replacement we have been told that the lamp is no longer available. The Infocus agent said that the lamp manufacturer doesn't exist anymore. We have been given an "upgrade" option to a current model - LP- 540. The projector (LP-350) we have is only 3 years old and replacing the lamp would be cheaper than "upgrading". Our I.T. guy laughed it off and told me this kind thing happens with IT equipment (write it off in 12 months) Has anyone heard of this from any other manufacturer and especially the home theatre PJ manufacturers. The main reason I ask is I am concerned how long I should keep my PJ at home. Is there anyway of checking the brand of the lamp in the PJ and who manufactures the lamp?
