Just changed my first set of lamps on our 950 and am curious what kind of life expectancy other users are getting. Mine were at 369 hours when I had to change them due to a "no voltage detected" error on the service side lamp. On our 98UVX, we were changing lamps about every 300 hours when they were rated for 500 hours. I was hoping that the life of the 950 lamps would be closer to expectations but so far, it's not looking promising. On the 98UVX you would ususally start to see tackiness in solid blacks when the lamps were approaching 300 hours but I haven't noticed any curing issues with the 950 so far.
