Can anyone provide the code reference that states a photocell can be used in an exterior emergency lighting fixture?

Remember, most code is proscriptive in nature, not prescriptive. I would look for the code that prohibits the use of a photocell instead.

"Photocell" only appears in the NEC once: Table 504.10(B), which does not apply to this application.

Why would someone want a photocell on an emergency light anyway? It's one more item that can fail.

To conserve energy of course..Why have an exterior light on during the day?

anyway, this is allowed see 700.22.
