Product Overview

The Philips MasterColor CDM-TC series is the preferred choice for designers who require the punch and sparkle of metal halide in the smallest possible footprint. The ceramic discharge tube technology ensures that color remains consistent within ±200K throughout the lamp's life, preventing the rainbow effect common in older HID systems. Integrated FadeBlock™ UV filtering minimizes the risk of fading for textiles and sensitive materials, making it ideal for high-end clothing boutiques and jewelry showcases. Despite its small size, this lamp offers up to 4x the lifespan of standard halogen alternatives with significantly higher energy efficiency.

• FadeBlock™ Technology: Significantly reduces UV radiation to protect colors and sensitive materials from photodegradation.
• Extreme Compactness: The T4 shape allows for very small, high-output luminaires that blend seamlessly into architectural designs.
• Superior Color Maintenance: High-purity ceramic discharge tube ensures brilliant light quality and color stability for years of operation.
• Extended Replacement Cycle: An industry-leading 20,000-hour average life reduces maintenance costs and disruption in busy retail environments.
