CMH 70W 942 G8.5 GE ConstantColor Lamp

The CMH 70W 942 G8.5 discharge lamp is a GE-certified metal halide light source designed for technical lighting applications that require high color rendering and long-term color stability.

Professional Lighting with Superior Color Rendering

This CMH discharge lamp offers a color rendering index (CRI) greater than 90, ensuring excellent color reproduction in environments where color accuracy is critical. Its color temperature of 4200K (natural white) makes it ideal for photography studios, television sets, art galleries, and showrooms where accurate perception of details is essential. The dedicated ballast stabilizes the light output at 6200 lumens throughout its entire operational life.

Applications in accent lighting and commercial displays

The G8.5 base and compact tubular shape allow for integration into small-sized fixtures, perfect for retail lighting, storefront displays, museum exhibits, and architectural accent lighting. The low power consumption of 70W reduces energy use compared to traditional light sources, while maintaining high light output in small to medium-sized spaces.

Reliability and continuous operation in demanding environments

With an average lifespan of 15,000 hours, this discharge lamp ensures reliable on/off cycles and stable light output over time—a critical feature for continuous commercial applications. ConstantColor technology maintains a constant color temperature, preventing color shifts that could compromise visual uniformity in multi-lamp installations.

Compatibility and Installation Specifications

The lamp requires a specific CMH discharge power supply (dedicated driver/transformer) and operates at stabilized line voltage. It is not dimmable; therefore, light intensity must be controlled using switching devices or through the host fixture. Its compact dimensions (⌀19mm × 90mm) make it compatible with many professional-grade projectors and technical spotlights.
