Product Overview

The Osram 54807 HPL 575/115/X UCF is the professional standard replacement lamp for ETC Source Four ellipsoidal fixtures and UCF-compatible stage lighting equipment. HPL (High Performance Long-life) technology delivers stable tungsten-balanced 3065K output with CRI 100 — providing accurate, consistent color rendering for theatrical, concert, broadcast, and film production lighting at 115V.

The 2,000-hour rated life is notably longer than standard tungsten halogen stage lamps, reducing lamp change frequency in production environments. The integrated heat sink base is an essential design feature — it actively manages thermal load within the enclosed fixture housing of the ETC Source Four and similar professional ellipsoidal instruments. The UCF (Universal Compact Filament) designation indicates compatibility across the range of UCF-type stage fixtures that accept this lamp family.

Confirm your fixture accepts 575W at 115V before ordering — HPL lamps are also available in other wattages and voltages, and substitution of the wrong wattage can damage the fixture's optical system or dimmer.

Compatible Applications

ETC Source Four ellipsoidal fixtures — HPL 575/115 is the specified source for ETC Source Four and UCF-compatible professional stage ellipsoidals.
Theatrical and concert production lighting — Stage, theatrical, and concert lighting at 115V requiring tungsten-balanced halogen output at 575W.
Film and broadcast location lighting — Tungsten-balanced 3065K output for camera-accurate studio and location production work.
Retrofit and maintenance replacement — Confirm wattage, voltage, and fixture compatibility before ordering.

Before Ordering — Verify

Wattage: Confirm the fixture is rated for 575W. HPL lamps are available in multiple wattages — substituting the wrong wattage damages the fixture optical system and dimmer.
Voltage: Confirm the supply circuit and dimmer are rated for 115V. Operating above rated voltage significantly shortens lamp life.
Base Type: Confirm the socket accepts Medium Bipin with Heat Sink. The heat sink is an integral part of the base — do not use in fixtures that do not accept this base type.
Physical Fit: Confirm 104mm MOL and 19mm diameter fit within your fixture's lamp housing.

Safety and Handling Guidelines

Do not touch the quartz envelope with bare hands. Skin oils cause hot spots leading to premature failure or lamp burst. Use clean gloves or a lint-free cloth. If accidentally touched, clean with isopropyl alcohol before use.
Allow Cooling: Allow at least 15 minutes after switching off before handling — this lamp operates at very high surface temperatures.
Correct Voltage Required: Use only in circuits rated for 115V. Overvoltage significantly shortens lamp life.
Approved Fixtures Only: Install only in fixtures rated for 575W HPL lamps with medium bipin heat sink base.
Handle with Care: Quartz halogen lamps are fragile. Avoid mechanical shock during handling and installation.
