Product Overview

The Sylvania 64325 Metalarc Powerball is a premium Ceramic Metal Halide lamp engineered for professional retail, gallery, and commercial accent lighting where color accuracy and long-term color stability are essential. The Powerball ceramic arc tube technology maintains color temperature within ±150K over the full lamp life — eliminating the pink or green color shifts common in standard Metal Halide lamps as they age. At CRI 90, the 4200K cool white output renders textures, fabrics, artwork, and merchandise with near-natural accuracy.

UV-Stop quartz technology significantly reduces UV radiation output, protecting UV-sensitive merchandise — fabrics, artwork, and colored materials — from fading and discoloration over time. The compact T6 form factor and G12 bi-pin base are optimized for enclosed track heads, recessed downlights, and architectural accent fixtures. This lamp requires a thermally protected pulse-start CMH ballast with a pulse-rated socket rated for ANSI M130/E.

Compatible Applications

High-end retail and boutique lighting — Apparel, jewelry, and luxury goods displays where CRI 90 color rendering and UV protection are required.
Art galleries and museums — High-CRI cool white for accurate art and artifact representation with UV-Stop protection against fading.
Commercial track and recessed accent lighting — Mall corridors, office lobbies, and architectural interior fixtures using G12 CMH track heads.
Architectural facade and accent lighting — Exterior and landscape accent fixtures requiring long-life, high-color-quality CMH sources.

Before Ordering — Verify

ANSI Code: Confirm the existing ballast is rated M130/E (39W pulse-start CMH). This lamp requires a CMH pulse-start ballast — it will not operate on probe-start MH, HPS, or standard Metal Halide ballasts.
Ballast Type: Requires a thermally protected CMH pulse-start ballast with a pulse-rated socket. Verify ballast compatibility before ordering.
Base Type: Confirm the lampholder accepts G12 Bi-Pin.
Wattage: Confirm the fixture and ballast are rated for 39W.
Fixture Type: Confirm the fixture is enclosed (E-type) — open fixture use is not permitted.
Physical Fit: Confirm 3.9" MOL fits within your fixture's lamp housing.

Safety and Handling Guidelines

Enclosed Fixtures Only: This lamp must be operated in enclosed luminaires only. The E-type rating requires UV-protective shielding — never use in open or unshielded fixtures.
Thermally Protected Ballast Required: Use only with a CMH pulse-start ballast with thermal protection. Incorrect ballast type will cause lamp failure.
UV Radiation: This lamp emits UV radiation. Proper fixture shielding is required. Do not expose skin or eyes to unshielded output.
Mercury Content: Contains mercury. Do not dispose of in regular trash. Recycle through an approved lamp recycling program in accordance with federal, state, and local regulations.
Allow Cooling: Allow the lamp to cool fully before handling or removal.

Compliance

Contains mercury — subject to applicable lamp recycling and disposal regulations. California, Washington, and other states may have mandatory take-back or handling fee requirements.
Verify RoHS compliance status and additional certifications with the Sylvania manufacturer specification sheet prior to use in regulated installations.
