I just bought a Revere 85 projector and then bought a few czx bulbs.

Are czx bulbs always this hard to install? I press down real hard but can't get it to twist and lock into position. Are they made to withstand all the pressure I'll apply when I try next time?

Also I was surprised to find the bulb lights even if it isn't twisted and locked into position.

I tried running film with the bulb "unlocked" but the bulb-area smoked so I shut everything down. Another post on this forum, from Patchett, said bulb smoke might just be dirt and grime smoke and that's what I think because the bulb didn't burn out and there wasn't any fire.

Questions:
1. Are all czx bulbs this hard to install?
2. Do people run their projectors without the czx bulb locked into position? Probably not.
3. Smoke from the bulb area must be dirt and grime? Yes, probably.

Thanks.

Try this
Remove the lamp then cleaned inside of socket (power unplugged)
lightly oil inside Might smoke a bit. Bulb should be easier to install.

As you found out, the lamp worked even not being fully turned, however, it is necessary for it to be turned the full 90 degrees after loading so that its filament is in line with the reflector, and condenser lens (if fitted).
Otherwise, you will not get the full amount of light on the screen.

Thanks folks. This and the other Revere entries at this forum will be a big help.

No one said anything so I'll assume the czx bulb is built to withstand the pressure I must exert to push it down into its slot. I can make that spring/button thing move with my finger although it is stiff.

OK I think this wraps it up. Someone at this forum made a good suggestion about contacting the vendor. Phil at www.8mm16mmfilms.com offered this advice:
"You need to make sure the large and small ear of the bulb base goes into the opening that fits them then push down and turn clockwise. It does take pressure to push it down but your resistance might be in turning it if there is rust or corrosion in the socket, unless the spring in your socket hardened over time and makes it hard to push down. It should go in fine."
