An elegant 5 W lamp with a transparent glass shade is suitable for creating general or decorative lighting in the interior. Comfortable diffused light with a high color rendering index provides high-quality lighting and maximum distinction 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.
