Stage and studio halogen lamp

The SYLVANIA HPL575/120 is a 575 watt halogen lamp built for ETC Source Four fixtures. It runs on 120 volts and uses a G9.5 two-pin base with an integrated heat sink. The T6 envelope produces 16460 lumens at a colour temperature of 3265 kelvin with a colour rendering index of 100. This lamp suits theatres, studios and architectural installations that demand precise colour fidelity.

Replacement for worn HPL575 lamps

Swap this lamp in when an existing HPL575/120 reaches its 300 hour rated life or shows output drop-off. The jump is worth it when colour accuracy matters for cameras or audience sightlines and the current lamp can no longer hold 3265 kelvin. Match the wattage, voltage and base exactly; the G9.5 heat-sink base and T6 shape must align with the fixture socket.

Fixture and power check before ordering

Confirm the fixture is an ETC Source Four rated for 575 watts at 120 volts. Verify the socket accepts a G9.5 two-pin base with heat sink and that the housing clears a T6 envelope. Ensure the dimmer or supply circuit can handle the 575 watt load without exceeding its capacity.

Questions about this item

What base does the HPL575/120 use and will it fit my ETC Source Four fixture?

The lamp has a G9.5 2-pin base with an integrated heat sink, which is the exact interface required by ETC Source Four ellipsoidal fixtures.

How do I install the lamp without shortening its 300-hour rated life?

Wear clean gloves, align the two pins with the socket, push straight in until the heat sink seats fully, and avoid touching the quartz envelope with bare fingers.

When should I plan to replace the bulb in a venue running shows nightly?

At 300 rated hours, a fixture used four hours per show will need a new lamp after roughly 75 performances; keep a spare HPL575/120 on hand.
