TELIO

Lighting that disappears into architecture.

A recessed linear luminaire that draws a pure, ultra-fine line of light into technical ceilings, with precision optics for glare-free offices. Designed in Belgium.

A pure line of light.

An ultra-slim extruded aluminium profile that sits between the slats of an Interalu SAPP climate ceiling. From below you see one clean line of light, not a fitting.

An optic for every LED.

Each LED has its own Herculux lens in clear PMMA. A micro-structured surface of fine facets diffuses the LED's bright point and shapes it into an even 55° beam, for unprecedented visual comfort.

Five parts. Nothing extra.

Body, LED board, lens, end caps and rotatable mounting clips. The DALI driver sits remotely, so the line stays ultra-slim along its whole length.

Slides in. Locks in.

TELIO sits flush with the underside of the slats. Two rotatable clips turn a quarter turn to lock it in the gap, with no visible fixings.

Each shape below a luminaire is its measured photometric solid. The coloured plane shows the illuminance they create together on the desks, 0.80 m above the floor.

Comfort you can measure.

The measured light distribution of TELIO, in candela. Tightly controlled above 60° to keep glare off screens, wide enough below it to light the desk evenly.

A lens built to stay clear.

The optic is moulded in PMMA acrylic, a material that resists UV light and keeps its clarity instead of turning yellow over the years.

Made for the ceilings architects draw.

Climate ceilings bring thermal comfort and quiet acoustics. TELIO adds light without breaking their lines, so the slat rhythm stays intact from the entrance to the last workstation.

Specify your line.

Choose the luminaire and its driver together. Every TELIO needs one DALI driver, ordered separately, and you can add 5 m extension cables where the driver sits further away.

5 m extension cables

One luminaire, one driver, plug and play.

Class III luminaires ship with cable and a male DC connector. The class II DALI driver plugs into it and connects to mains and DALI through a Wieland GST18I5 5-pin connector.

1

Connect

Plug the luminaire's male DC connector into the driver's 0.8 m output lead, or add a 5 m extension (0040953) in between.

2

Mount

Lift TELIO into the slat gap and turn both mounting clips a quarter turn to lock it.

3

Control

Wire mains and DALI through the Wieland GST18I5 connector. Set the current by dip-switch, or by NFC with 0040952.
