Philips 13113C-04 Light Bulb

Despite being categorized as an LED replacement in some systems, this specific Philips 13113C-04 model is an incandescent bulb designed for specialized equipment. It is engineered to deliver the specific heat and light output required by older hardware.

No, this bulb is not designed for standard household fixtures. It requires a specific 8V power source and features a P15S30 prefocus base, which is incompatible with standard screw-in residential sockets.

The P15S30 is a specialized single-contact prefocus base with a 15mm collar. This design ensures the filament is perfectly aligned within your equipment's optics, which is critical for devices like projectors or medical instruments.

This bulb is designed for high-intensity, specialized applications rather than general illumination. Because it operates at a high wattage to produce a specific light output, the filament is engineered for performance over longevity, resulting in a shorter operational lifespan.

You should only use this bulb in equipment specifically rated for an 8V, 50W power supply. Using it in a device with a different voltage will likely cause the bulb to fail immediately or potentially damage your equipment.
