TRILUX Siella LED panel - efficiency and comfort for modern working environments

The Siella from TRILUX is a high-quality recessed LED luminaire with a microprismatic cover, specially developed for demanding applications in offices, corridors, foyers, conference rooms, sales areas and waiting zones. Its elegant design (format 625 mm x 625 mm) blends seamlessly into system ceilings with visible trunking. Surface-mounted or recessed ceiling installation is also possible with optional accessories.

Thanks to its optical system with prismatic PMMA surface, Siella offers glare-free lighting (UGR < 19) and symmetrical wide light distribution with a beam angle of 93° - ideal for screen-compatible work in accordance with EN 12464-1.

The integrated LED technology offers maximum flexibility: the luminaire luminous flux and light color can be adjusted in eight levels (multilumen, multicolour) - from 2600 lm to 4400 lm with a rated power of 18.2 W to 31 W. With a luminous efficacy of up to 154 lm/W and a selectable color temperature of 3000 K (warm white) or 4000 K (neutral white), the Siella creates the right lighting atmosphere at all times. A high color rendering index of Ra > 80 and the narrow color location tolerance (≤ 4 SDCM) guarantee a harmonious and natural color representation.

Robustly manufactured from an aluminum frame and sheet steel on the back (coated white, similar to RAL 9016), the luminaire measures 620 x 620 mm with a height of just 29 mm and a weight of 2.3 kg. It is equipped with protection class I, protection rating IP20, and impact resistance to IK03 and can withstand temperatures from -20 °C to +25 °C.

Equipped with an external, digitally dimmable DALI control gear (DALI-2 standard, Touch DIM), the Siella complies with all current EU directives (CE marking, ENEC certification). Both the light source and control gear are interchangeable in accordance with ecodesign requirements.

TRILUX Siella - the perfect solution for efficient, flexible and comfortable lighting in modern working and living spaces.
