Stage Studio Halogen Bulb

The SYLVANIA HPL 575W 120V lamp is a tungsten halogen bulb built for stage, studio and architectural fixtures. It uses a G9.5 two‑pin base with an integrated heat sink and an ultra compact filament design. The bulb is made to fit ETC Source Four fixtures and similar professional lighting units.

Sustained Output Stability

The ultra compact filament construction improves light collection and efficiency during continuous operation. Rated at 2000 hours at full 575 watt draw, the lamp maintains consistent output without the rapid lumen drop common in shorter‑life halogen types. Colour temperature holds at 3050K and the CRI stays at 100 throughout the rated life.

G9.5 Base Practical Limits

The G9.5 two‑pin base with heat sink dictates fixture compatibility; only sockets designed for this base and the 575 watt thermal load should be used. Operating on 120V supply is required, and the 2000‑hour rating assumes proper voltage and adequate ventilation in the fixture housing.

Questions about this item

How much heat does the 575 watt HPL halogen bulb produce when running continuously?

At 575 watts the lamp converts nearly all input power into heat, so it will become very hot during extended use; ensure the fixture has adequate ventilation and keep flammable materials clear.

What fixture base is required for the G9.5 2-pin HPL bulb to operate?

The bulb needs an ETC Source Four or compatible fixture with a G9.5 2-pin socket and built-in heat sink; it will not work in standard household sockets.

Can the 120 volt HPL 575W lamp replace older 575 watt stage bulbs with different bases?

No — cross-references such as OSRAM 54815, GE 92435 and Ushio 1002283 share the same G9.5 base and 120 V rating, so older lamps with other bases or voltages are not interchangeable.
