CMH PAR30 35W 4200K E27 GE ConstantColor Light Bulb

The GE Lighting CMH PAR30 35W 4200K E27 discharge lamp is a metal halide light source designed for technical lighting applications that require high color rendering and a concentrated light distribution.

Retail and window display lighting with superior color rendering

With a color rendering index (CRI) exceeding 90, this CMH light source ensures accurate color reproduction—essential in commercial environments where the aesthetic appeal of products is critical. The concentrated 25° beam allows for precise accent lighting on storefronts, displays, and areas of visual interest, enhancing merchandise and displays with contrast and depth.

Applications in museum and art gallery lighting

CMH discharge technology offers a natural light spectrum ideal for illuminating works of art, photographs, and artifacts. The color temperature of 4200K (cool white) and high CRI allow collections to be displayed without color distortion, maintaining the visual fidelity required by museums, galleries, and specialized exhibition spaces over time.

Technical lighting in industrial and manufacturing environments

In work environments where clear and accurate vision is essential, the PAR30 CMH discharge lamp is a reliable solution. The 25° beam angle concentrates the light on specific areas, reducing glare and improving the perception of details during quality control, assembly, and visual inspection tasks.

Design Features and Compatibility

The lamp features a standard E27 base, ensuring compatibility with common fixtures and lamp holders. The PAR30 shape allows for direct integration into existing reflector fixtures without the need for adapters. Although it belongs to energy class G, CMH discharge technology maintains higher luminous efficiency than traditional incandescent sources, with an average lifespan of 10,000 hours that reduces maintenance costs.

Operating Specifications and Limitations

This discharge lamp is not dimmable and therefore requires standard power supply circuits without dimming systems. Its stable color temperature of 4200K and CRI greater than 90 make it particularly suitable for applications where color consistency is prioritized over light modulation.
