Philips ELC/10H 13163 - MR16 250W, 24V, GX5.3 dichroic lamp (1,000h lifespan)
The Philips ELC/10H 13163 is a low-voltage (24V) dichroic halogen lamp with a GX5.3 base , designed for professional applications requiring a clean beam, stable color, and high reliability: medical and optical equipment , microscopy , projection and fiber optics , as well as entertainment lighting (discos, theaters). The 10H version offers a long lifespan of 1,000 hours thanks to P3 (Pinch Protection) technology, which allows operation at higher temperatures while maintaining consistent light output and reducing premature failures. The MR16 (R50) dichroic reflector helps dissipate some of the heat to the rear of the optical system , resulting in a cooler and more uniform front beam. It is dimmable , has a universal operating position , and features a CRI of 100 , typical of tungsten, making it ideal when color rendering is critical.
