Any idea what the capacity of the transformer is? Judging from its physical size, it doesn't look to be much larger than required to simply power the two lamps (the original intent, of course). It also appears that the lamps are burned out or have a lot of hours on them.
One more question; is the 277v. entry in the back center of the fixture? If so, it looks kinda like NM cable.
From an old codebook (I have a new one coming); Art. 700-13 - "No appliances and no lamps, other than those specified as required for emergency use, shall be supplied by emergency lighting circuits."

Talk about a little knowledge being dangerous. This may have been a project designed and installed by the chairman and treasurer of the tuesday-afternoon ‘over-80’ engineering club...with its two active members—a retired telephone installer and career supply sergeant. ;-)
But they had the foresight of future-proofing—a spare outlet for the swill-mart carbon-monoxide detector when they go on sale in February. [Might have to wait ‘til one of the exit-sign lamps burns out to avoid overloading the 277-120V transformer.] They reached the sign with four stacked chairs from the piano room, and got materials by mail from the Sears and Roebuck catalog—summer 1955 farm & garden edition.
