Product Overview

The Philips MasterColor CDM ED23.5 series utilizes advanced ceramic arc tube technology to provide significant advantages over traditional quartz metal halide lamps. By maintaining a higher operating temperature, these lamps achieve better lumen maintenance and superior efficacy of approximately 90 lumens per watt. The 4000K color temperature offers a neutral, clean white light that is ideal for accentuating modern textures and vibrant colors in retail displays. Engineered with Universal Burn capabilities, this lamp provides consistent performance regardless of fixture orientation, significantly reducing the Total Cost of Ownership through energy savings and extended re-lamping cycles.
