SATCO Lighting S8000 5W LED Emergency Driver, 120-277V

One part covers both. The Satco S8000 LED emergency driver accepts 120 through 277 volts, so the same unit works on 120V residential-style circuits and on 277V commercial lighting branch circuits. For contractors standardizing emergency backup across a mixed-voltage building, that means one SKU instead of two.

The S8000 is a 5 watt emergency driver. In a loss of normal power it drives the connected LED load at 5 watts, which is a reduced output level intended to keep egress paths lit rather than to maintain full fixture brightness. Size your fixture selection around that 5 watt figure when planning egress coverage.

An LED emergency driver like the Satco S8000 installs with an existing LED fixture and takes over that fixture's LED load when normal power drops, so the light you already have becomes the emergency light. A standalone emergency unit is a separate wall-mounted fixture with its own lamp heads. The driver approach keeps ceilings clean and uses the architectural fixture already specified, which is why it gets used in offices, corridors, and retail buildouts where bug-eye heads are not wanted. The S8000 is a 5 watt unit operating on 120 to 277 volts.

There is a single version, ordered as Satco manufacturer part number S8000. No voltage variants or output variants to pick between, since the one unit covers the full 120 to 277 volt range at 5 watts.
