Application

Circadia is a new premium office luminaire family designed for workplace wellness, productivity and sustainability.

With its dual light component design consisting of a diffuse element and a central array of optical chambers, Circadia provides premium quality, low-glare illumination for the modern workplace.

Delivering a sense of comfort, wellbeing and harmony for occupants with minimal energy consumption, Circadia is the product of choice for asset owners looking to achieve or enhance the WELL, Green Star, NABERS or other sustainability performance rating of their buildings.

 

Design

Innovative optical chamber design delivers optimal wide beam distribution with low glare.

Made from advanced microstructured film that offers controlled batwing light distribution, Circadia’s diffuse element allows for wider spacing with fewer luminaires required in the lighting array, making it a cost-effective solution for new fitouts and retrofit projects alike.

Diffuse aperture also provides a pleasant transition between ceiling and light source.

The product exceeds BCA 2019/J6 requirements via optimised beam distribution.

 

Optics

White optical chambers with internal diffusers form the primary, task lighting component whilst an independent light source is used to create the diffuse peripheral component.

 

Control

Organic Response Technologies Sensor Node 3 (SN3) is the standard sensor control offering with the Circadia fixed-CCT variants. Other sensor control methods are available upon request.

 

Circadian Lighting

The combination of LED chips with the right spectral distribution and an optimum beam distribution achieves ideal vertical illuminance levels with high Circadian Stimulus (CS) and Circadian Lighting (Cla) values.

 

Lifetime

Constant Light Output (CLO) feature comes as standard across the range and ensures that there is no lumen depreciation for the lifetime of the product.

 

Light Quality

CRI90+ as standard with R9>50, COI compliant (4000K), initial colour consistency better than 3 SDCM. 

 

Installation

Easy to install and an attractive option at only 60mm thickness, the Circadia is suitable for locations where limited ceiling depth is a concern.

 

Mounting Options

- Recess Kit

- Surface Mounted Kit
