SYLVANIA 64162 | MC39T6/U/G12/930 METALARC® POWERBALL® 39W 3000K G12 Ceramic Metal Halide Lamp

The Sylvania 64162 (MC39T6/U/G12/930) METALARC® POWERBALL® is a commercial-grade, ultra-high-efficiency **39W ceramic metal halide (CMH) lamp** engineered for high-end retail accent lighting, architectural facades, gallery showrooms, and specialized outdoor landscape luminaires. Featuring a standardized **G12 bi-pin twist-lock ceramic base** and a heavy-duty **T6 quartz glass profile**, this high-output discharge module utilizes an advanced spherical ceramic arc tube geometry to optimize thermal dynamics and eliminate focal color shifting. Leveraging premium metal halide salt chemistry to achieve an elite **93 CRI** color precision index, it radiates a rich, crisp **3000K Warm White** illumination path. Delivering **3,100 initial lumens** and engineered to comply with federal UV-Stop threshold guidelines, this premium German-manufactured light engine offers an exceptional **15,000-hour rated average service life** inside enclosed, pulse-rated architectural fixtures.

POWERBALL® Spherical Arc Tube Control and High-CRI Phosphor Tuning

Sylvania METALARC® POWERBALL® lamps resolve the color variance and rapid degradation common in legacy quartz metal halide bulbs by utilizing a round, high-purity **ceramic arc tube**. This rounded core profile allows for highly uniform chemical distribution and precise internal thermal containment, ensuring stable color rendering and minimal lumen drop over long-term operations. To protect sensitive commercial inventories, textiles, and art pieces, the outer clear T6 envelope incorporates integrated **UV-Stop quartz barriers** that significantly filter out degrading short-wave ultraviolet radiation. This advanced composition achieves precise target chromaticity coordinates ($x = 0.432$, $y = 0.396$), providing premium architectural networks with deep color contrast and crystal-clear structural highlights.

• Elite 93 Color Rendering Index: Projects an exceptionally authentic color field, enhancing complex merchandise textures, fabrics, and vibrant architectural finishes.
• Integrated UV-Stop Envelope Shielding: Filters out aggressive ultraviolet paths to prevent fabric fading, artwork solarization, or plastic discoloration inside high-end displays.
• Precision German Engineering: Fabricated to tight micro-tolerances in Germany, ensuring absolute mechanical and electrical uniformity across large multi-lamp building setups.
• Sustained Luminous Efficacy: Engineered to provide a robust **15,000-hour rated average life**, significantly minimizing system replacement cycles and operational labor costs.

System Integration, Ballast Guidelines & Operational Safety

• Mandatory Enclosed Fixture & Type-E Ruling: In strict compliance with ANSI industrial safety profiles, this E-Type metal halide module **must exclusively be operated within fully enclosed luminaires**. The host fixture must feature tempered, heat-resistant glass shielding capable of containing high-temperature ceramic fragments in the rare event of an internal arc tube rupture or envelope fracture.
• Thermally Protected Circuit Notice: This high-intensity discharge cell **must only operate on thermally switched, compatible electronic or magnetic ballasts** matching the ANSI C130 benchmark. The electrical network must maintain a nominal Open Circuit Voltage (OCV) of 230V or higher (minimum 209Vrms without an ignitor in circuit) and integrate overcurrent protection to stop catastrophic terminal overloading.
• 4000V Socket Pulse Rating Caution: Due to high ignition striking voltages required during startup, this lamp must be paired exclusively with specialized **4000V pulse-rated G12 lampholders**. Standard low-voltage bi-pin sockets will immediately suffer terminal flashover, degradation, or dielectric failure.
• Federal Non-Ionizing UV Radiation Warning: This lamp can cause severe skin irritation, burns, and intense ocular inflammation from short-wave ultraviolet radiation if the outer clear glass envelope becomes punctured, cracked, or shattered. Do not operate where people remain for more than a few minutes unless adequate glass shielding or protective safety lenses are used. This product complies with FDA radiation performance standard 21 CFR subchapter J (USA: 21 CFR 1040.30; Canada: SOR/DORS/80-381). If the outer sleeve breaks, shut off system power instantly and allow components to cool down before handling.

Recommended Professional & Commercial Applications

• High-End Retail Display & Accent Lighting: Perfect choice for luxury fashion storefront track systems, jewelry cases, automobile showrooms, and department store focal walls.
• Architectural Outdoor Landscapes: Excellent for ground-mounted flood washes targeting historical monuments, corporate brick facades, garden landscape pathways, and public pillars.
• Museum & Art Gallery Showrooms: Ideal light engine for tracking spots focusing on fine art paintings, historical artifacts, and high-contrast exhibit pieces where a 93 CRI rating is mandatory.
