I just got a keystone 8mm projector but the light bulb is burnt out abd I have no manual and can not find one online. Can anyone help me out?

Hi Katie,

According to Replacement Lightbulbs.com your projector uses either of these two lamps:

CZX/DAB

or

CXY/CXK

Unfortunately these are discontinued bulbs and they get a little pricy sometimes. The other shoe that needs to drop is that if you want to use the projector long-term you should probably buy two!

-these won't become more available than they are now.

You should try fishing around on E-bay a little: sometimes you can get better deals because someone has old store stock to clear out.

-above all: be very careful handling these bulbs. Oils from skin contact can cause the glass to shatter because they get wickedly hot! It's best to handle them with cotton gloves or failing that something like a clean handkerchief.

It's described as a P28s base

From the looks of this it seems to be a (gently) twist until it pops out:

P28s

-not the usual kind of stuff Sears sells! (I'm impressed!)

If you are at all uncertain you should E-mail customer service at Replacement Lightbulbs.com. They are pretty helpful.

We have P28s lamps in some theatre lanterns at the club I belong to - the wrong ones for this projector, but I remember having to push gently down on the lamp to remove or insert it as there is a sprung centre electrical connection pad which prevents it turning if you don't.
