The lamp, designed for installation in magnetic tracks of the MAG-ORIENT series with a width of 26 mm, provides ample opportunities for accent lighting.
The compact light module can be rotated around its axis by 350° and deflected by 90° in the vertical plane, precisely and quickly adjusting the direction of the beam. The emission angle, variable in the range of 19–29°, allows you to instantly set the shape and size of the light spot.
Thanks to its excellent color rendering index (CRI>98), it provides high-quality light and reference color rendering: this lamp is indispensable for lighting museum exhibitions, exhibition halls, galleries and other premises with high requirements for light quality.
The figured body made of aluminum, painted black, will harmoniously complement interiors of different styles.
