I have 4 projectors and I have spare lamps for 3 of them (the last one isn't used too often). So in my mind I have been well prepared for any mishaps. I have had very busy times lately with little time for feature films, but on Saturday I was finally going to watch a film with my wife on the 16mm at the cabin which I was really looking forward to. 20 minutes into the film the sound went missing. The exciter lamp had died. What a fool I am that hasn't thought about getting a spare for that too, only the main lamp. I wasn't very happy to say the least (I had no other 16mm projector there). New lamps has been ordered and is on its way. Rookie mistake and very frustrating.
