Sylvania Powerball® Ceramic Metal Halide 64882 (MC20T4.5/U/G8.5/830) Lamp — 20W | 3000K Warm White | 1,700 Lumens | Enclosed Fixture Rated

The Sylvania Powerball® Ceramic Metal Halide 64882 (MC20T4.5/U/G8.5/830) Lamp is a commercial-grade, high-efficiency high-intensity discharge (HID) ceramic metal halide bulb engineered for luxury retail showcase graphics, fashion boutique accent tracks, museum display spots, and high-end architectural outdoor feature recessed downlights. Delivering 1,700 initial lumens of crisp 3000K warm white illumination, this compact 20-watt specialty tube utilizes an advanced ceramic arc tube to achieve a stable color rendering index of 83 CRI. Outfitted with a premium single-ended G8.5 2-pin plug-in base and an ultra-low mercury fill weight, it provides an extended 15,000-hour rated average service life when paired with approved ANSI M156 electronic control ballasts.

ADL Supply Expert Application & Replacement Guide

The Sylvania Powerball® 20W G8.5 ceramic lamp is an established retail display facility maintenance baseline specified universally for high-density boutique tracks, showcase glass boxes, museum display displays, and outdoor architectural accent columns. Delivering an exceptional color rendering package via rare-earth tri-phosphor chemistry, this premium discharge lamp maintains tight color point stability across its service life cycle, suppressing the rapid yellow-green color shift or drastic lumen fading common in legacy quartz metal halide bulbs.

Critical ANSI M156/E Enclosed Fixture Ratings and Arc Voltage Parameters: Electrical contractors and commercial facility maintenance teams executing routine site upgrades must analyze current fixture parameters prior to checkout: this lamp carries a strict ANSI M156/E code rating, certifying it exclusively for Enclosed Luminaire installation fields. The "/E" suffix establishes that this ceramic discharge capsule must operate behind an enclosed tempered glass containment lens capable of holding hot fragments in the rare event of an end-of-life arc tube rupture.

Additionally, this bulb operates at a continuous ballast-regulated **arc voltage of 95V AC with a running current draw of 0.210 Amperes**. Initializing the cold gas column requires an intense pulse-start ignition spike—the host ballast circuit must deliver a **4,000V (4 kV) pulse strike down the load wire lines**. Ensure the G8.5 2-pin tracks click fully flush into the lampholder to resist vibration-induced micro-arcing. Following any sudden utility interruptions, a mandatory 10–15 minute hot restrike cool-down period must pass to allow internal gas tube pressures to normalize before the igniter can re-strike the arc safely.

Operation, Safety & Mounting Compliance

Low-Frequency Electronic Ballast Signal Stabilization

This ceramic lamp interfaces natively with high-efficiency electronic pulse-start ballast systems. By converting utility inputs into highly regulated low-frequency square-wave signals, it eliminates the visual arc flicker, micro-humming, and high acoustic resonance loops common when running bulbs under magnetic line signals. This advanced power stabilization ensures display spots project matched color properties without baseline color point shifting over extended lifecycles.

Low-Mercury Vapor Dosing and Safe Bulk Recycling Protocols

This high-intensity metal halide lamp incorporates a finely metered internal mercury fill dose to initiate its high-efficacy visibility track. While fully compliant with standard commercial building metrics and meeting Federal FDA radiation performance codes (21 CFR Subchapter J), the presence of mercury vapor dictates that spent lamps must be securely processed through certified regional commercial bulk recycling repositories during facility maintenance change-out sweeps rather than discarded into standard municipal solid waste streams or common landfills.
