63 W EX39 Corncob LED for HID Retrofit

This mogul-screw LED replaces 250 W high-pressure sodium or metal-halide lamps in industrial and outdoor fixtures. It fits existing EX39 sockets and operates on 100 to 277 V supplies without rewiring the ballast.

Lumen-selectable output and passive cooling

A built-in switch chooses 7,800 lm, 8,500 lm or 8,500 lm at 3000 K, 4000 K or 5000 K so installers match the original light level and colour on site. Passive cooling eliminates fan noise and moving-part failures in enclosed housings.

Shatter-resistant plastic housing for enclosed

The ED23-1/2 envelope is rated for fully enclosed luminaires and resists impact in high-bay or canopy applications. It is not suited for fixtures that require a smaller diameter bulb or a lower lumen package than 7,800 lm.

Questions about this item

How often will the fan inside the 63 W corncob bulb need cleaning or replacement?

The bulb uses passive cooling with no fan, so there are no moving parts to clean or replace during its service life.

Which limit appears first when the 63 W LED runs continuously at full output?

Thermal limits are managed by the passive heatsink; the driver maintains stable output within the 100–277 V range until the fixture’s ambient temperature exceeds the rated maximum.

How much noise and heat does the 63 W EX39 bulb produce when left on all day?

Passive cooling makes it completely silent, and the housing stays warm but safe to touch because waste heat is spread over the full ED23-1/2 surface.
