OSRAM 64258 Halogen Bulb

The OSRAM 64258 is a 20W 12V halogen lamp with a G4 bi-pin base. It produces 350 lumens with a colour rendering index of 100. The rated life is 2000 hours. It suits low-voltage fixtures in homes or outdoor settings.

Single-ended low-voltage design

The single-ended construction fits compact sockets that accept only one contact orientation. Low-voltage operation at 12V requires a compatible transformer or driver. The G4 bi-pin spacing matches standard low-voltage holders. No additional accessories or software are included in the package.

Simple bi-pin installation

Push the pins firmly into the G4 socket until they seat fully. Handle the quartz envelope with a clean cloth to avoid oil contamination that shortens lamp life. Verify the fixture supplies 12V before fitting the bulb. Mismatched voltage is the most common cause of immediate failure.

Questions about this item

How often will the OSRAM HLX 64258 halogen bulb need replacement?

The rated life is 2000 hours, so replacement depends on daily usage; at three hours per day it lasts about two years.

What limits continuous operation of this 20 W G4 halogen lamp?

The filament reaches full temperature quickly, and the 2000-hour rating is the primary limit; no thermal throttle or duty cycle is specified.

How much heat and power does the 12 V 20 W halogen bulb produce when run all day?

It draws 20 watts continuously and converts most energy to heat; the G4 bi-pin base and fixture must handle the sustained thermal load.
