GE ConstantColor 20W CMH MR16 Ceramic Metal Halide Lamp 3000K GX10 40D – 42691

GE ConstantColor 20W CMH MR16 GX10 Lamp – 42691

The GE ConstantColor CMH20/MR16/UVC/830/GX10/WFL is a compact 20W ceramic metal halide reflector lamp designed to deliver bright, stable warm white light from an MR16-sized lamp. This model has now been discontinued, making our remaining stock particularly useful for maintaining existing fittings that require the original GE 42691 lamp.

Combining the efficiency and stability associated with high-pressure sodium technology with the bright white light and colour rendering of metal halide, the GE ConstantColor range provides consistent light output and colour performance throughout the lamp’s service life. Its ceramic arc-tube construction helps minimise the chemical changes that can otherwise affect the colour of metal halide lamps as they age.

The lamp produces approximately 1,000 lumens with a 3000K warm white appearance and a 40° wide flood beam. This makes it suitable for retail displays, architectural lighting, hospitality venues and other commercial environments where controlled, good-quality accent lighting is required.
