Nice one, @Stridsvognen. I went with @jfinnie's advice earlier on here noting the gains of longevity, safety and warranty assurance sticking with an original complete JVC lamp. It is worth noting how profusely I use my projector, too: It is my main display, so it is always on for extended periods of time daily. So, with jf's advice and no assurance of a genuine USHIO lamp at the time, I chose the safe albeit expensive option.I got in touch with USHIO, they are sending some pictures to the factory to check.
The main purpose is to find a place to buy original USHIO lamps, bare lamps, as with these older JVC projectors its hard to justify the price of a new lamp with housing from JVC, so if possible to actually buying the exact same USHIO bulb, for a significantly lower price, it would help keeping some of these projectors alive and in good helth.
However, am I right in assuming that you are of different mind to jfinnie? And that a proper lamp plus used housing has no negatives? Interested to hear a possible flip-side. If I did not have any doubts I would have stuck to my original plan of trying to acquire just a bare USHIO lamp, especially as times are hard. But I had no assurance at the time. At least I have retained some sort of peace of mind and the money went to a good and much needed business. So, I look forward to your findings which will hopefully relieve concerns for myself and others going ahead.
Best wishes, safe keeping and good-health to you,
