Match ELC/10H, Philips order code 136580, and the complete 250 W / 24 V / GX5.3 / 1,000 hours configuration. Standard ELC and the ELC-3, ELC-5, ELC-7, and ELC-10 classes can look alike but differ in life, output, color, filament, and optical performance.

Equipment compatibility
Qualified ELC-10 equipment classes
Reliable public model-level references were not found for this 1,000-hour class, so compatibility is intentionally limited to equipment that explicitly names ELC-10 or ELC/10H.
- Professional overhead-projection equipment explicitly specifying ELC-10 or ELC/10H
- Professional fiber-optic illuminators explicitly specifying ELC-10 or ELC/10H
- Entertainment fixtures explicitly specifying ELC-10 or ELC/10H
- One-hour photo-finishing equipment explicitly specifying ELC-10 or ELC/10H
The equipment manual and installed-lamp label take precedence.

Safety
Use only in an approved enclosed professional fixture rated for 24V, 250W operation with the specified ELC life class, optical alignment, guards, ventilation, and cooling. Disconnect power and allow the fixture to cool completely before service. Handle the lamp and reflector with clean gloves or a lint-free cloth.
