SYLVANIA 64363 | MC39TC/U/G12/830 Metalarc® Powerball® 39W Ceramic Metal Halide Lamp

The Sylvania 64363 (MC39TC/U/G12/830) is an industrial-grade, ultra-efficient **39W ceramic metal halide lamp** from Sylvania’s premier Metalarc® Powerball® 800 Series. Running on a specialized **ANSI C130/E** ballast circuit, this single-ended **T6 clear capsule bulb** features a rugged, precision-molded **G12 ceramic bi-pin base** engineered for absolute alignment and optics stabilization. Producing a powerful **3600 initial lumens** of rich, inviting **3000K Warm White (830)** light with a high color rendering index (**82 CRI**), it combines an advanced pulse-start firing arc tube with a long **15,000-hour rated service life**. Manufactured in Germany to precise OEM standards, this lamp is built exclusively for high-end **enclosed commercial track spots** and downlight fixtures.

The Round Powerball® Arc Chamber Advantage

Sylvania Metalarc® Powerball® lamps use a patented round ceramic arc cell configuration that completely re-engineers internal thermal dynamics. Unlike traditional cylindrical ceramic or quartz burners with cool corner areas, the spherical Powerball® capsule creates exceptionally uniform heat distribution. This reduces thermal stress, controls chemical migration, and achieves an elite efficacy of **92 lumens per watt (lm/W)**. This architecture ensures excellent color stability over the 15,000-hour runtime, keeping retail floors and galleries uniform without the color shifting common to older HID systems.

• Pulse Start Ignition: Engineered strictly for compatible electronic control gear or pulse-rated magnetic ballasts, accelerating warm-up cycles and preserving long-term lumen retention.
• Universal Burning Vector: Designed to fire and operate cleanly in any spatial orientation or tilting position without degradation of light output or color properties.
• Integrated UV Protection: Formulated with a specialized UV-Stop quartz outer glass jacket that filters harsh ultraviolet bands, drastically reducing color fading or yellowing on merchandise and displays.
• Chromaticity Coordinates: Lab-calibrated to rigorous spectral targets (X: 0.432, Y: 0.396) for crisp, repeatable warm white highlights across multi-fixture configurations.
