Advanced Ceramic Powerball® Technology

The Sylvania Metalarc 64974 combines the compact size of a T4.5 capsule with the spectral power of ceramic technology. By utilizing a spherical ceramic arc tube, the Powerball® design ensures more uniform temperature distribution, which translates to better color rendering and reduced lamp-to-lamp color variation. This pulse-start lamp is compatible with both electronic and magnetic ANSI-standard ballasts, providing flexible installation options. Its 94 CRI ensures that textures and colors are rendered with life-like precision, making it indispensable for environments where visual impact is critical.
