Purpose and Fit

This Antique Light Bulb Co. halogen lamp delivers 500 watts at 120 volts with a GY9.5 prefocus base. It produces a 3200K colour temperature and a colour rendering index of 100 for accurate colour reproduction. The T6 shape suits fixtures designed for this specific form factor.

Who It Serves and Who It Doesn't

The bulb serves stage, studio or projection equipment requiring a GY9.5 base and high colour fidelity. Its rated life of 50 hours makes it unsuitable for general room lighting or any application needing long intervals between replacements. Buyers seeking lower heat output or extended service intervals should consider alternative technologies.

Build Integration

The GY9.5 two-pin base locks into compatible sockets without tools, freeing the installer from wiring modifications. Operating at 120 volts, it connects directly to standard mains circuits within the fixture. The compact T6 envelope allows use in tight housings where larger halogen capsules would not fit.

Questions about this item

Does my fixture need a GY9.5 2-pin prefocus base to accept this bulb?

Yes — the lamp uses a GY9.5 2-pin prefocus base, so the socket must match that exact base type.

Can I run this 500 W halogen on a 120 V dimmer I already own?

The bulb operates at 120 V and is dimmable with standard incandescent/halogen dimmers rated for at least 500 W.

How do I confirm the 3200 K output and 100 CRI are correct once installed?

Power the lamp and verify a warm-white 3200 K appearance with full-spectrum colour rendering (CRI 100) using a calibrated meter or reference chart.
