Technical Specifications

Product Overview

The 64970 is part of Sylvania's METALARC POWERBALL Ceramic family, combining pulse-start metal halide characteristics (good efficacy, long life) with the improved lamp-to-lamp color consistency and high CRI of a ceramic arc tube. Compared to quartz metal halide lamps of similar wattage, it holds CCT and color rendering more tightly over the 15,000-hour rated life. This item was renumbered from Sylvania product 64363 to 64970; both numbers refer to the same lamp.

METALARC POWERBALL Ceramic T4.5, T6, T7.5 and double-ended products must be operated in enclosed fixtures capable of containing particles as hot as 1200°C. Operating position is Universal, and the lamp requires a 4000V pulse-rated socket.

Compatible Applications

• Accent and track lighting
• Retail and museum displays
• Facade lighting
• Indirect luminaires
• Landscape luminaires
• Recessed downlights

Before Ordering – Verify

• Confirm the base/socket type (G12) matches your fixture before ordering — ceramic metal halide bases are not interchangeable across wattage tiers.
• Fixture must be enclosed and rated to contain particles as hot as 1200°C — this lamp is not rated for open fixtures.
• Confirm the socket is 4000V pulse-rated; standard sockets are not sufficient for this ignition system.
• The circuit must include overcurrent protection (i.e., a thermally switched ballast).
• Minimum open circuit voltage for starting is 209 VRMS, measured with the ignitor in the circuit.
• This lamp was formerly sold under Sylvania product number 64363 — confirm you are ordering current stock under 64970 (MC39T6/U/G12/830 PB).

Safety and Handling Guidelines

• WARNING: This lamp can cause serious skin burn and eye inflammation from shortwave ultraviolet radiation if the outer envelope of the lamp is broken or punctured. Do not use where people will remain for more than a few minutes unless adequate shielding or other safety precautions are used.
• Allow the lamp to cool completely before handling or relamping — ceramic metal halide lamps operate at high internal pressure and temperature.
• Always disconnect power at the fixture or breaker before servicing.
• No special handling requirements during installation (gloves not required); always follow normal safety precautions.
• Contains mercury — dispose of per local regulations (see Compliance).

Compliance

• Contains mercury; dispose of/recycle according to federal, state, and local regulations.
• ANSI ballast code C130/E — confirm ballast compatibility before installation.
• For maximum energy savings and system performance, Sylvania recommends operating on QUICKTRONIC MH electronic metal halide ballasts.
• When paired with a compatible QUICKTRONIC MH ballast, this lamp is eligible for the Sylvania QUICK 60+ System Warranty (see Sylvania for full terms).
