What This Bulb Is

The Satco S13121 is a 70 watt LED corncob replacement for metal-halide or high-pressure sodium HID lamps. It operates on 100 to 277 volt circuits and uses an EX39 mogul extended base for direct installation in existing industrial fixtures.

Who It Suits

Facilities managers upgrading warehouse, parking-lot or canopy lighting to 4000K neutral white will find this a straightforward retrofit. Buyers who need a different colour temperature, a lower wattage, or a standard E39 base instead of the EX39 mogul extended base should look at other options.

The Deciding Specification

The EX39 mogul extended base is the single specification that determines fit; it only seats in sockets designed for that specific base type. Verify the fixture socket before purchase because an EX39 lamp will not work in a standard E39 mogul socket.
