The recessed spotlight can be installed in rooms with high levels of humidity or dust: the compact aluminum body has dust and moisture protection at IP54.
The lamp is designed to create directional lighting (narrow beam angle 36°). A low discomfort coefficient and a high color rendering index (CRI>90) guarantee high-quality light that is pleasant to the eye and does not distort the shades of objects, so the lamp can be used in commercial, public or residential premises.
It is easily installed in the mounting hole using springs, and the included driver allows you to safely and quickly connect the lamp directly to a 230 V network.
