Sylvania 64969 MC70T6/U/G12/830 70W 3000K G12

The Sylvania Metalarc Powerball® 64969 MC70T6/U/G12/830 Lamp is an industrial-grade, 70-watt ceramic metal halide (CMH) single-ended T6 tubular lamp engineered for high-performance retail tracks, museum accenting, and commercial architectural downlights. Delivering 7,000 initial lumens of comfortable 3000K warm white light, this elite lamp incorporates a patented spherical ceramic arc tube geometry that maximizes thermal distribution and eliminates structural corner stress points. Outfitted with an industry-standard G12 ceramic bi-pin base and integrated UV-Stop quartz cladding, it achieves an impressive 100 lumens-per-watt efficacy and a rich 87 CRI rating over an extended 15,000-hour rated average service life.

ADL Supply Expert Application & Replacement Guide

The Sylvania 64969 Metalarc Powerball is an industry standard widely specified by lighting designers, electrical contractors, and commercial facility engineering groups across jewelry display stores, corporate lobbies, museum exhibitions, high-end apparel rows, and exterior architectural accent fixtures. Utilizing Sylvania’s advanced spherical arc tube core, this T6 capsule eliminates the localized hotspot fatigue and green spectral shifting standard in legacy quartz metal halide bulbs—retaining exceptional color point stability and uniform candlepower across its entire lifecycle.

Critical High-Voltage Ballast & Socket Lead Notice: This lamp must be driven exclusively by low-frequency electronic or specialized magnetic pulse-start ballasts certified for **70W ANSI M139 or M98 ceramic metal halide circuits**. It cannot operate on older probe-start ballasts or standard mercury vapor control gear. Because pulse-start ignition systems inject highly intense **4,000V (4kV) starting pulses** across the socket terminals to strike the arc, installers must confirm that the G12 lampholder wiring and lead insulation are rated for high-voltage pulse thresholds. Poorly insulated wire lines or compromised contacts will arc over, presenting a severe fixture fire risk.

Operation, Safety & Mounting Compliance

Thermal Cycling, Restrike Delays, and Venting

Following a cold strike initiation, this high-intensity discharge source requires an initialization window of 2 to 4 minutes to fully vaporize internal gas elements and achieve steady spectral color rendering. In the event of a circuit interrupt or localized voltage sag, a hot restrike safety delay of 7 to 15 minutes must be allowed. This lets internal operating arc tube pressures cool and balance completely before the pulse-start electronic ignitor can safely re-fire the lamp capsule without creating structural electrode fatigue.

Glass Integrity Management and Maintenance Rules

Never handle the clear T6 quartz glass body wrapper with bare skin during installation sweeps. Human fingers automatically deposit microscopic alkaline body oils that bond chemically to the quartz casing during active heating cycles. This organic contamination blocks heat dissipation, producing localized thermal points that fast-track envelope devitrification, micro-fracturing, and premature failure. Installers must execute re-lamping sweeps using clean tech gloves, a microfiber lint-free cloth, or its original cardboard sleeve wrapper. Meticulously clean the glass with isopropyl alcohol if accidental baseline tracking takes place.
