The Par20 (parabolic aluminized reflector) design of this lamp provides excellent light distribution and focus. The Ceramic Metal Halide (CMH) technology used in this lamp offers several advantages over traditional High-Pressure Sodium (HPS) or Metal Halide (MH) lamps. CMH lamps emit light more efficiently, producing more lumens per watt, resulting in energy savings and reduced operating costs.

This particular lamp has a color temperature of 3000K, making it a warm white light source. The color rendering index (CRI) of 80 indicates that this lamp can effectively render a wide range of colors, making it an excellent choice for applications that require accurate color representation, such as food processing or retail display.

The 39W power consumption of this lamp is relatively low compared to other high-intensity discharge (HID) lamps, making it an energy-efficient option for applications where energy savings are a priority. The lamp is also designed for long life, with a rated lifespan of 20,000 hours, reducing the need for frequent lamp replacements.

The Ceramic Metal Halide lamp is also known for its fast lamp-up time, typically reaching full brightness within minutes of being turned on. This is an advantage in applications where rapid illumination is essential, such as cold storage units or horticultural grow lights.

This lamp is compatible with most standard Par20 reflectors and ballasts, making it a versatile option for a wide range of applications. The lamp is also RoHS compliant, meaning it meets the restrictions on the use of certain hazardous materials in electronic and electrical equipment.

In summary, the GE 29487 CMH20PAR30/SP10 39W Par20 Ceramic Metal Halide Lamp is a high-performance, energy-efficient, and long-lasting lighting solution suitable for a wide range of commercial and industrial applications. Its warm white light with excellent color rendering and fast lamp-up time make it a standout choice for applications where accurate color representation and rapid illumination are essential.
