The 5 W recessed luminaire has a discreet and minimalist design and is distinguished by very high light quality: color rendering index CRI>90 and a low discomfort rating provide even, eye-pleasing lighting that does not distort the shades of objects.
Two radiation angle options will allow you to create accent lighting of individual parts or a slightly more diffused local illumination.
The compact aluminum housing is easily installed into the mounting hole using springs. The increased level of dust and moisture protection allows the model to be used in rooms with high levels of humidity and dust.
