Halogen Lamp for GX5.3 Fixtures

The Antique Light Bulb Co. FHS halogen bulb delivers 300 watts at 82 volts with a GX5.3 two-pin base and MR13 envelope. It produces 650 lumens at 3300K colour temperature and a CRI of 100. The rated life is 70 hours and the overall length is 1.755 inches. Suitable for stage, studio or medical fixtures that specify this exact lamp code.

Buyers Needing Long-Life or Low-Voltage Alternatives

This lamp is not for users who need extended operating time between replacements; the 70-hour rating means frequent changes in continuous-use settings. It is also unsuitable for fixtures wired for mains voltage or for sockets other than GX5.3, as the 82-volt requirement and two-pin base are fixed. Anyone needing a cooler-running or higher-efficacy source should consider different technologies.

The 82-Volt GX5.3 Specification Decides Fit

The single specification that determines compatibility is the 82-volt GX5.3 base; the fixture must supply exactly 82 volts and accept a two-pin MR13 lamp. If the socket or supply voltage differs, the bulb will not operate safely or at all. Verify the fixture manual for the FHS or 54979 designation before purchasing.

Questions about this item

How much heat and power will the 300 W halogen filament produce when run continuously?

The bulb draws 300 watts at 82 volts and converts most of that energy into heat; expect the MR13 envelope to become very hot within minutes and remain so for the 70-hour rated life.

What fixture and supply does the GX5.3 2-pin base require?

A socket that accepts a GX5.3 bi-pin base and a stable 82-volt power source are both essential; the 5.3 mm pin spacing will not fit other bases.

Will the 3300 K output and 100 CRI match older halogen lamps I keep in the same circuit?

Yes, the 3300 K colour temperature and 100 CRI replicate traditional halogen light quality, so mixed installations appear consistent.
