SATCO Lighting 67-138 Emergency Light, Dual Head, 120/277V, White Finish

Both. The 67-138 dual head emergency light is a dual-voltage unit rated 120/277 volts, so the same fixture works on standard 120V branch circuits in residential and light commercial spaces and on 277V circuits common in commercial and institutional buildings. That means one part number can be standardized across a mixed-voltage facility instead of stocking two.

It is a standalone dual head emergency light, not a lettered EXIT sign. The two adjustable heads throw egress path illumination when normal power drops. If your code official requires an illuminated EXIT legend at the door, you need a separate exit sign or a combination exit/emergency unit in addition to this fixture.

Two heads let you cover two directions from one mounting point, which is what a corridor intersection, a stairwell landing, or a wide open area usually needs to hold the required path-of-egress illumination. A single head only covers one run. The 67-138 gives you two adjustable heads on one 8.25 by 4.05 inch body, so one fixture and one circuit tap does the work of two.

White only. The 67-138 is built in a white finish, which is the single option offered on this model, so it blends with typical painted drywall and white ceilings. If you are matching a building standard that calls for a black or architectural housing, this is not the unit for that opening.

The manufacturer part number is 67-138, also written 67/138 in Satco literature. Ask for it by that number when you are matching existing units in a building so you get the same dual head 120/277V white fixture rather than an adjacent model in the family.
