4050-80 Bulb Type?

Fire Alarm Help
1

Hi all,

I have a Simplex 4050-80 light plate (120V AC version) that I will be using for a special project, and need to know the size/style of bulb that goes into the lamp socket. I’m planning on turning the light plate into a decorative piece (along with the horn and backbox) by adding a lamp cord to the light and using it as a decorative lamp to go on display. I’d like to replace the original, incandescent bulb with an LED bulb of the same style so that 1: the plastic light cover won’t warp from heat generated by the incandescent bulb if it is lit for prolonged periods of time and 2: I don’t want to burn out the original 40+ year old bulb. The socket is bayonet style, and I think the bulb is an (S6S?) style bulb, but I’m not too sure. Just don’t want to order the wrong bulb. Any help is appreciated. Thanks again.

I’d also like to get LED bulbs for the two 2903-9001 light plates I own, but I have no idea where I’d find an LED bulb that:
#1: Is 24VDC.
#2: Is yellow-tinted like a normal incandescent bulb.
#3: Can “fade” on & off also like a regular incandescent bulb.

Looks like Home Depot might have what you need.

6s6 24v E12 bulbs. It’s the same bulbs I used for my early 4050-80s

Is it an LED bulb that meets all my criteria though? Do you have a link to a listing?

Ohh I didn’t read the LED part haha. Unfortunately, I don’t have a link to a listing for LED bulbs
