Product Identity

This is a 500 watt halogen bulb with a GY9.5 base operating at 120 volts. It produces light at a 3200K colour temperature and carries the OSRAM EHA designation. The lamp is supplied in new condition.

Suitable Uses

The bulb suits fixtures requiring a GY9.5 single-ended halogen source at 500 watts and 3200K output. It is not for buyers needing a longer service life than the rated 50 hours, nor for sockets that accept only bi-pin or screw bases. It also does not fit low-voltage systems or dimmers not rated for halogen loads.

Deciding Specification

The rated life of 50 hours is the single figure that determines whether this lamp matches the maintenance schedule of the installation. A colour rendering index of 100 confirms full-spectrum output for critical colour tasks.

Questions about this item

Should I pick the 500 W version or a lower-wattage halogen for my fixture?

Choose the 500 W model only if your fixture is rated for 500 W at 120 V and accepts a GY9.5 base; a lower-wattage bulb will draw less power but also produce less light.

What does the 3200 K rating look like in a real fitting?

The 3200 K output gives a warm white glow similar to traditional studio tungsten, ideal for photography or stage work where accurate colour rendering matters.

How does the GY9.5 base limit what I can install this in?

The GY9.5 base with 9.5 mm pin spacing fits only sockets designed for that exact base; it will not work in standard Edison or bi-pin sockets of other sizes.
