Lithonia Lighting EDGR RMR EL M4 LED Edge-Lit Exit Sign, Recessed Mount

The EDGR edge-lit exit sign is dual voltage, rated 120 or 277 V, so the same unit drops onto either circuit without ordering a separate version. Draw is 3 W, which is what lets a lot of these run off one branch circuit in a corridor retrofit.

Both are available: EDGR 1 RMR EL M4 is the single-face unit and EDGR 2 RMR EL M4 is the double-face. Use single-face where the sign sits against a wall or at the end of a corridor and is only read from one direction. Use double-face where the sign hangs or is seen from both approaches, such as mid-corridor or in an open lobby. The face count is fixed at the time of order, not field convertible.

Mounting is listed as both recessed and surface for the EDGR, so it can go into a ceiling or wall opening or sit on the finished surface where there is no cavity to recess into. That matters on a renovation where some openings have plenum space above and others are slab or hard ceiling.

Yes. The EL in EDGR 1 RMR EL M4 is the emergency battery option, so the LED faces stay illuminated when normal power drops. That is the configuration most facilities need, since an unswitched AC-only exit sign goes dark in an outage.

The EDGR edge-lit exit sign is listed to NFPA 101, along with CA Title 20 and ULBAA. Those are the three standards stated for it, which covers the life safety code reference most AHJs look for on means-of-egress signage plus California's appliance efficiency regulation.

Environmental conditions are given as indoor and outdoor for the EDGR, so it is not restricted to conditioned interior space. The housing is aluminum, which is what makes that practical in a damp or unconditioned location like a garage deck or covered walk.

The EDGR is a silver aluminum edge-lit unit, so it reads as a thin brushed-metal panel rather than the white thermoplastic box of a standard exit sign. That is why it gets specified in retail, medical, hospitality and office spaces where the appearance of the egress signage is part of the design. If you are standardizing a building, note that it will not visually match existing white plastic exits.

No. The EDGR uses static LED illumination rather than lamps you swap, so there is no bulb to stock or replace. For an MRO program the only consumable item is the emergency battery in the EL version.
