The 12v 100w (A1 231) dichroic reflector lamp blew in my Eumig projector and I quickly found a replacement on the internet. Popped it into the projector but although the lamp itself is just as bright to the naked eye, the projected image is much dimmer.
I'm wondering if there are special versions of this lamp (made with the same reference number) that don't have the necessary focused beam for film projection but have a much wider beam for kitchen ceilings or something. Anybody know more about this?

Re: ciné projector lamps
Yes, Tom. There are cheaper versions intended for use in "disco lights" and similar. Use Ebay and search for lamps SPECIFICALLY for your machine. If you can get the XENOPHOT (you can search that on Google) version you will get an even brighter picture with a small additional cost.
It's a common problem; once you've learnt you will always look for the genuine article. Perhaps it's result of the general lack of interest in real film these days: one forgets the important things about real projection!

Re: ciné projector lamps
Thanks for the info. Maybe my lamp (marked 'projector lamp' on the box) will last a lot longer than an over-run Xenophot (I remember those). My projector's mains transformer is set on 240v, and aren't we now on 220v? I could reset that and get a few more volts to the lamp that way.

Re: ciné projector lamps
The UK voltage is theoretically 230 V +10% /- 6%, AC, 50 Hz. But that is a fiddle to tie in with EU rules. In fact it is still the old 240 V +/- 6%. (Oh the fun bureaucrats can have with percentages.)
Tom - take a look at http://www.burycine.org.uk/cinealive/help.html and use their search system to find possible dealers near you.

Re: ciné projector lamps
Tom,
Xenophots are not "over-run". I have used real film for many years and use my Eumigs and Elmos regularly. I have never found ANY difference in lamp life between Halogens and Xenophots, but there is a great difference in brightness.
If your "Cheapo" bulb box is marked "projector lamp" it's because that is what it is.... a lamp for a disco "projector", whose only function is to project coloured lights onto alcohol fuelled idiots.
Whatever you do, keep your transformer setting at at 240 volts; the 220v volt setting will only result in ridiculously short life.
Your projector works on tried and tested "old" technology. Give it the respect it deserves and it will give faithful service for years to come. It is not a modern consumer item that can be discarded when the latest "all singing, all dancing" version comes along.

Re: ciné projector lamps
Thanks for your thoughts gentlemen. I did laugh at the 'alcohol fuelled idiots' description 
Interestingly enough the 'proper' lamp that failed tended to give a hot-spot in the centre of the screen - and in combination with the projector lens working wide open gave a good stop difference centre to corner. Not really noticeable in most films but it bothered me, and so for film transfer I used a diffuser just in front of the gate which evened the light out beautifully. I've written this up for Positive Image.
This alcohol fuelled idiots disco lamp that I now have fitted gives a much more even spread of light, and I find I can now dispense with the diffuser. So there's an easy stop I've clawed back.
