An 8 W rectangular luminaire with an aluminum body in three noble shades (black, gold, titanium) is suitable for creating directional lighting in interiors.
A narrow radiation angle allows for precise illumination of interior items, and a high color rendering index ensures high-quality lighting and maximum distinguishability of color shades.
The luminaire is easily mounted on the APRIORI track using a special mount, which allows two installation options: with the optics up or down, opening up space for a variety of lighting design solutions.
It is possible to control the brightness of the lamp by PWM (PWN) using a dimmer or non-addressable control when using a DALI, 0–10V or TRIAC driver.
