SYLVANIA 64361 | METALARC® POWERBALL® 70W Ceramic Metal Halide G12 Lamp

The Sylvania 64361 METALARC® POWERBALL® (MC70T6/U/G12/830PB) is a professional-grade, high-efficacy **70W ceramic metal halide lamp** engineered for high-end retail accentuation, commercial displays, and structured floodlighting arrays. Outfitted with a precision **G12 Ceramic Bi-Pin base (12mm pin spacing)** and an unshielded **T6 clear quartz envelope**, this German-made bulb generates an impressive **7,000 initial lumens** in an inviting **3000K Warm White** color presentation. Featuring advanced spherical arc-tube engineering to secure an elite **87 CRI** color rendering accuracy baseline, it delivers a **15,000-hour average rated life** across universal burning positions. This pulse-start lamp operates natively on standard **ANSI M139/E or M98/E track and downlight networks**, providing industry-leading lumen maintenance and stable color rendering throughout its operational lifecycle.

POWERBALL® Spherical Technology and Universal Operational Efficacy

Sylvania METALARC® POWERBALL® lamps feature a patented spherical ceramic arc tube layout that optimizes thermal consistency across the internal plasma chamber. This advanced design minimizes standard institutional color shifting and ensures an outstanding **100 lm/W luminous efficacy** threshold. Operating smoothly across **universal burning orientations**, this premium pulse-start lamp delivers a rapid warm-up loop profile and retains a high **5,600 mean lumens** maintenance plateau over time. Built with integrated **UV-Stop quartz technology**, the outer jacket actively filters damaging ultraviolet radiation to limit standard product or trim fading in luxury indoor retail areas.

• Elite Spherical Arc Tube Structure: Promotes uniform heat distribution inside the discharge cell, yielding superior color stability and elevated light output over conventional cylindrical designs.
• High-Fidelity Visual Accuracy: Boasts a premium 87 CRI rating that beautifully highlights retail textures, jewelry faceting, and fine museum artwork with sharp, realistic contrast.
• Universal Burn Orientations: Engineered to mount safely and execute flawlessly in any positional orientation inside tracking heads, downlight canisters, or accent luminaires.
• German-Engineered Build Integrity: Manufactured to demanding specifications in Germany, securing precise mechanical tolerances and repeatable electrical performance.

Mandatory Installation Requirements & Safety Guidelines

• Enclosed Luminaires Only (E-Type): This lamp is strictly rated for use **only inside enclosed fixtures** capable of containing hot glass fragments in the rare event of an internal arc-tube rupture. Do not operate in open-face luminaires.
• Ballast Controls: Must be paired with thermally protected electronic or magnetic ballasts fully compliant with industry standard **ANSI M139/E or M98/E** (also rated for **C139/E or C98/E**) specifications. Electrical tracks must integrate proper overcurrent circuit protection loops.
• Socket Ratings: Use exclusively with heavy-duty **4,000V (4kV) pulse-rated** G12 lampholder sockets to handle high-voltage starting ignition pulses.
• System Voltage Metrics: Requires a minimum system open-circuit voltage profile of 209V RMS (230V nominal) to establish a clean plasma arc strike without an external ignitor.

Critical Safety & UV Exposure Notice

WARNING: This high-intensity discharge lamp can cause severe skin burns and acute eye inflammation from shortwave ultraviolet (UV) radiation if the outer glass envelope is cracked, punctured, or broken. Do not operate in spaces where people will remain for more than a few minutes unless adequate external protective shielding is utilized. If the outer bulb breaks, immediately isolate power loops and extract the component safely. This lamp fully complies with FDA radiation performance standard 21 CFR Subchapter J in the USA and standard SOR/DORS/80-381 in Canada.

Recommended Commercial & Retail Applications

• Specialty Retail Showrooms: Perfect for illuminating jewelry counters, fashion boutiques, auto showrooms, and luxury storefront displays with high-efficacy, true-to-life light.
• Museums & Art Galleries: Provides controlled, high-CRI illumination over historical artifacts, sculptures, and painting exhibits while the UV-Stop layer limits fabric color decay.
• Architectural Facade Illumination: Ideal for outdoor structural column washes, monument spotlights, and landscape highlight layouts when housed inside enclosed, weather-rated outdoor enclosures.
• Commercial Downlighting: Perfect for corporate lobbies, upscale hotel reception desks, and municipal building main atriums using high-ceiling recessed downlights.
