With an impressive **83 CRI** and a **15,000-hour rated service lifespan**, this lamp is designed to provide consistent, high-contrast illumination in space-constrained fixtures while maintaining excellent color stability throughout its operational life.

Precision Ceramic Optics and Long-Term Stability

Sylvania’s Metalarc Powerball technology utilizes a spherical ceramic arc tube to provide uniform light distribution and superior thermal stability. The **T4 clear bulb design** ensures minimal optical interference, making it an ideal choice for high-end track lighting, museum displays, and luxury retail showcases. Its universal burn position allows for flexible installation, while the integrated **UV-Stop quartz** envelope significantly reduces ultraviolet emissions, protecting delicate merchandise and fine art from accelerated fading.

• Pulse Start Technology: Ensures faster warm-up times (2-3 minutes) and superior lumen maintenance compared to standard probe-start metal halide lamps.
• Compact Form Factor: The small T4 profile with a GU6.5 base enables the use of sleek, minimalist architectural fixtures.
• Consistent Performance: The ceramic arc tube prevents color shift over time, ensuring all lamps in a multi-head track system maintain a uniform color appearance.
• Long Life Cycle: Rated for 15,000 hours, this lamp dramatically reduces maintenance labor and replacement frequency in commercial environments.
