What is this emergency light?

My school has a bunch of these recessed emergency lights. There are two different versions, and this is the first and probably older one. I’ll post a picture of the other one when I can.

Here’s the other version.

i’m not sure what brand it is, but those do resemble mid-century ceiling fixtures made by various companies. I went to a Catholic school that had some of those made by the Art Metal company of Cleveland.

These are from the 80s so that’s a possibility. Do you have any pictures of them? I will say they resemble the Lithonia Lighting ELSQ/ELSQM and the Chloride SPU series. The main thing that tells me that the later two aren’t it are the test button location.

no, but you can go on usmodernist.org and browse the various architecture magazines (Architectural Forum and Record) from the 1950s and 60s. You’ll find all sorts of vintage ads there.

I’m not too sure on the models. But I do know that I’ve seen these at a few schools I’ve been too, and the collage I visit during some school trips is loaded with working ones.

I’m planning on going to that same collage so maybe someday I can snap a picture of one of them turned on.

I guess I should update this. I think I figured them out. They seem to be Emergi-Lite PSC18-2s

I’m pretty sure that’s the same one I’ve seen, I managed to snap a few photos

There seems to be another similar looking light to these that I saw, here’s a photo of one with the cover off

I’ve seen a few of these old emergency light units in older buildings with more decorative interiors—usually around places that also had crystal chandeliers, which made the fixtures stand out less. From the looks of it, I’m pretty sure it’s an early model from Dual-Lite. That curved lens design and housing shape were pretty common in their 80s emergency lighting gear.

I should place another update on some newer info.

They weremade by both Emergi-Lite and Dual-Lite. Emergi-Lite ones have the only data sheet (a sheet that was created in 2007 surprisingly) I have been able to uncover and are the most common ones that are found. All together they are most commonly found dead and are quite rare now.
