Direct HID Replacement

The Satco S49677 is a 120W LED lamp designed to replace traditional HID fixtures. It fits an EX39 mogul base and operates on Type B ballast-bypass wiring for direct line voltage connection. This standard bulb suits commercial and industrial installations requiring a straightforward retrofit.

Maintenance Teams Seeking Simple Retrofit

Facilities crews who want to eliminate ballast maintenance and reduce energy draw will find this economy Hi-Pro model practical. It is not intended for fixtures that require an enclosed rating, dimming control, or a specific optic distribution not provided by the bare lamp.

EX39 Mogul Base Compatibility

The lamp uses an EX39 mogul base, so the socket in the existing fixture must accept this specific base type. Verifying the base match is the single step that confirms whether this bulb can be installed without an adapter.

Questions about this item

How do I install this 120W LED HID replacement in an existing EX39 mogul-base fixture?

Bypass or remove the old HID ballast, then screw the lamp directly into the EX39 socket so the internal Type B driver receives line voltage.

What maintenance will this Economy Hi-Pro lamp need over its service life?

No routine maintenance is required; the sealed LED module and driver are not user-serviceable, so the entire lamp is replaced at end of life.

What limits continuous operation of this 40K colour-temperature bulb in an enclosed fixture?

The Economy Hi-Pro thermal design is rated for open or ventilated fixtures; sustained use in a fully enclosed housing will overheat the driver and shorten lifespan.
