Hi does anyone have experience of these projectors. It's a beautiful little machine that can be hand cranked or run with it's built in motor.I've only recently bought it, and while it projects a very steady image, it's not very bright. It currently has 240v 100w lamp. Any suggestions? MIKE

Have you tried a different bulb? That would be my first check, but I usually try to look for a more modern lamp I can convert too. I would also check any sort of heat absorbing glass, etc that may be in the line of fire, as I have had those interfere, and of course what type of lens does it use, as some suck up all of the light...While I have a bunch of 9.5 projectors I have never had one of these Noris juniors' but I think they are more along the lines of the baby, than the specto and weren't designed to project very far...Is yours the green model?

I was given one of these when at school in 1958. \\\\\\i still use it for viewing short films and films back from processing. The mains voltage lamp gets hot and there is no forced cooling, a heat filter drops to prevent burning. I converted the lamp to a 50 w 12v Halogen which I got from Homebase and use a 12v transformer from an old computer device. The barrel shutter makes for flicker, and prevents the fittin of a better lens. The lens is only a doublet of about 2.5 aperture. With the sprocket feed it is much easier to use than an Ace and the lamp conversion is easier. Mine was bought from Profitts of Bolton, I wonder if they still exist ? Good luck with it.

Hi Dino and Peter, thanks for your replies. Dino yes it is a greenish colour, I think the way forward is to fit a more modern lamp. Peter I didn't realise it had a barrel shutter, does this make it the equivalent of a 2 bladed shutter? Increasing the light could make flicker more obvious, to be honest the picture is so dim at the moment I hadn't notice any flicker!I also didn't know that a barrel shutter restricted the type of lens either. Peter I live in Chorley, only a few miles from Bolton and sorry Proffits is long gone. Thanks again MIKE

The very first projector I had was one of these and never noticed any problem with dim light. I cannot remember now - but is there any up & down adjustment for the lampholder. If there is it may be the holder has slipped down so the lamp filament is not directly opposite the condenser'
