GE 43258 Mogul Screw LED Replacement

This GE 43258 LED bulb fits a Mogul Screw EX39 base and replaces 250 W metal halide or high-pressure sodium lamps. It produces 800 lm at 4000 K while drawing 80 W and carries a 50,000-hour rated life for indoor general-purpose lighting.

Suits high-bay and low-bay fixtures needing

Buyers who require dimming or a shatter-resistant envelope should look elsewhere because this model is not dimmable and has no shatter-resistant coating. It is also rated for indoor use only, so outdoor installations are not supported.

Ballast-dependent EX39 base determines fit

The lamp operates on a ballast-dependent circuit through its Mogul Screw EX39 base, so the existing ballast must be compatible for the bulb to function. Verifying ballast compatibility is the single specification that decides whether this is the right part.

Questions about this item

What does the 800 lumen output mean for brightness in a real fixture?

The bulb produces 800 lumens, replacing a 250 W metal halide or high-pressure sodium lamp while drawing only 80 W.

How does the EX39 mogul screw base and ballast-dependent design affect installation?

The EX39 base fits mogul sockets, but the lamp requires the existing HID ballast to operate; it will not run on direct line voltage.

What are the physical dimensions for fitting this cylindrical bulb?

The bulb measures 4 inches in diameter and 8 1/2 inches overall length.
