Carlo - modern LED path light with variable colour temperature The Carlo path light is a reliable light source that can also be adapted to individual preferences. Its replaceable GU10 LED lamp has a colour temperature of warm white 2,700 K or universal white 4,000 K, which can be selected via a small switch directly on the lamp. The tall, cylindrical body made of black cast resin is equipped with a clear cover; an inner layer ensures that the light is evenly diffused all around.
