What this bulb is and who it serves

The Ushio HPL-575/115X+ is a 575W 115V halogen lamp rated for 2000 hours. It produces 12360 lumens at a 3050K colour temperature with a CRI of 100. The T6 envelope measures .72 inches in diameter and 4.09 inches overall length. It fits fixtures using a G9.5 2-pin base with heat sink.

Installing the HPL-575/115X+

Align the G9.5 two-pin base with the socket and push until the heat sink seats firmly. Avoid touching the clear quartz envelope with bare fingers; skin oils create hot spots that shorten the 2000-hour life. Ensure the fixture is rated for 575W at 115V and that ventilation around the compact 4-C8 filament is unobstructed.

Who this suits and who should look elsewhere

Stage and studio professionals needing maximum output from ETC Source Four fixtures will benefit from the 20% lumen gain over the prior design. Buyers requiring a different voltage, lower wattage, or a base type other than G9.5 cannot use this lamp. Those needing significantly longer rated life should consider alternative technologies.

Questions about this item

How do I confirm the Ushio HPL-575/115X+ is performing correctly after installing it in my ETC Source Four fixture?

The lamp should deliver 12360 lumens at 3050K with a CRI of 100. If output appears significantly dimmer or colour shifts, verify the 115V supply and G9.5 base seating.

What comes in the box with the Ushio HPL-575/115X+ and what must I source separately?

The package contains the 575W halogen lamp with G9.5 2-pin heat-sink base. You must supply a compatible ETC Source Four fixture rated for 115V 575W operation.

Which version of the Ushio HPL-575/115X+ should I choose for a standard 115V ETC Source Four fixture?

Select the 115V 575W model with G9.5 base (part 1000671). It matches the fixture voltage, fits the socket, and provides 2000-hour rated life at 12360 lumens.
