The Antique Light Bulb Co. 12W PAR36 operates at 12 volts with a G53 screw-terminal base. It draws 12 watts and is rated for 50 hours of life. This incandescent lamp serves as a direct replacement for GE 12720 in emergency building lighting fixtures.

Replaces GE 12720 in PAR36 Fixtures

This bulb upgrades any PAR36 emergency unit that currently uses a GE 12720 or equivalent H7557 lamp. The swap is worth it when the existing lamp has reached its 50-hour rating or when a fresh 12V 12W source is needed for code-compliant egress lighting. Builders who need a different base type or a longer-life technology should look elsewhere.

Questions about this item

Will the PAR36 diameter and G53 screw terminals fit my existing emergency fixture?

The bulb uses a PAR36 form factor with a G53 screw-terminal base, so it matches fixtures designed for that exact size and connection type.

How do I install the H7557 correctly, and what is the common mistake?

Turn off power, align the screw terminals with the fixture contacts, and tighten each terminal securely; the frequent error is leaving a terminal loose, which causes flicker or no light.
