A 10 W luminaire for three-phase tracks is used for lighting public, commercial, and exhibition spaces where quick and easy changes to light accents are required. One type of luminaire offers very flexible accent lighting: 5 color temperature options and an adjustable beam angle allow you to customize the size and shade of the light spot for optimal emphasis in a particular area. The side mounting of the light module increases the tilt and rotation angle of the body, expanding the possibilities for accent lighting.
