The Canadian AK manual describes it as an ordinary domestic 15W light bulb, and going on the illustrations in the wiring diagrams of the Scotch Yoke manual and also page 175, it's of the normal pear shape. Somewhere I thought I saw mention of it being frosted; may have been the AK manual.

Looks like white frosting (soft white) didn't come out until 1947 so I guess that means it's clear for sure.

As we call them in British terminology, "pearl" bulbs were certainly available long before that. I think I have some 1920's squirrel cage filament bulbs in pearl in my collection somewhere. Here's an ad from 1932.

You know the funny thing about this is GE probably never published anything on it because they figured people would use what they wanted. But I want what originally came in it. stlvortac, from the drawings it looks like a normal shaped bulb so I'm thinking an appliance bulb is probably best. cablehack, what are you using in your two machines and if 15W can you share some pictures to give an idea of how it looks? I've yet to hook up a cabinet light. From the Horseshoe for your glove videos I spent time pausing the video as the light went on and off from the salesman playing with the switch. Even dim, I couldn't see a filament so I'm thinking it was frosted.

Should there be a gasket around the bulb?
I'd assume not as even modern refrigerators don't have that.

Yes there is; there is a rubber shroud that grips reasonably tightly around the bottom of the bulb. I removed it in my CA-1 because it was in very poor condition. I should at least seal around the edge of the light socket with silicone sealant, but nothing seems to have turned green yet. I think one of the other reasons for having it might be to prevent moisture entry into the cabinet, although the back of the light socket is well sealed. From the 1934 sales brochure:

Thanks! Its actually perhaps a slight bit dimmer than the 40 watt clear bulb that was in it. My new one has the commercial rating of 130 volts. its a bit dimmer under a normal 115-120 volt load and usually last forever.
I looked over the service manual and can't find a thing about factory wattage. The bulb size in the diagram is comparable to modern appliance bulbs.

Wow!
All this discussion about a lightbulb. I've always just use 25 W appliance bulbs in mine. Thankfully on the older cabinets the DR's use, there isn't a lightbulb to worry about.
I once had a 1939 General Electric flat top that had a very old light bulb. It appeared to be a frosted 25 W bulb.
