Sirio-SAPP: lighting that blends seamlessly into the climate ceiling

A climate ceiling heats and cools through the ceiling - but the lighting has to fit into it seamlessly. Sirio-SAPP is designed specifically for that.

Sirio-SAPP: lighting that blends seamlessly into the climate ceiling

More and more offices, schools and healthcare facilities are choosing a climate ceiling. That places special demands on the lighting: luminaires and the climate system share the same ceiling plane. Sirio-SAPP is the luminaire that fits into it effortlessly.

Built for the SAPP climate ceiling

Where standard luminaires often struggle to integrate into a metal baffle or climate ceiling, Sirio-SAPP is purpose-made for Interalu's SAPP system. The luminaire sits neatly in the ceiling grid and respects the thermal performance of the climate ceiling.

Comfortable, low-glare light

With a lens-and-louver optic, Sirio-SAPP delivers an even, low-glare light image (UGR <19) - pleasant in offices and at screen workstations. High colour rendering (CRI 80 or 90) keeps colours true to life. Want to know more about glare? Read our article on UGR and low-glare light.

Three lengths

Sirio-SAPP is available in 900, 1200 and 1500 mm, so the luminaire matches the dimensions of the ceiling and the space. This creates clean, continuous light lines in the climate ceiling.

Where Sirio-SAPP excels

Sirio-SAPP is ideal for offices, healthcare, education and public spaces with a climate ceiling, where comfortable, calm light is desired. Curious how to match lighting and climate ceiling? Also read our article on climate ceilings and lighting.
