With a variety of different length options, continuous rows of ModiFly can be used to fill an open office for comfortable, ambient illumination. The image above shows ModiFly with a static link between modules for continuous rows of luminaires.

Finish options

Predefined patterns
Shake things up, and modify spaces with ModiFly luminaires to create an endless array of patterns – whether it be pods of pendants or interconnected hexagons in space – ModiFly allows for ultimate flexibility, making lighting the key element of architectural design.

The patterns below are just some of the examples ModiFly has to offer. Choose from one of these, or customize your own pattern.

ModiFly articulating links
Harness the ultimate flexibility of on-site articulation of luminaires. Create one-of-a-kind designs with unique shapes and precision angles. ModiFly’s patent-pending design of the factory pre-wired Bi, Tri, and Quad-link systems allow for articulating luminaires on-site, allowing for final touches of angulation to be just perfect.

*Static links apply to continuous runs only; all other links apply to patterns/shapes.

On-site luminaire rotation
With fool-proof angulation, rotation of pendant modules to achieve the look desired becomes flawless.

Simply match up the markings on the arms of the link to rotate fixture modules 7.5 degree increments (with markings at 15 degrees).
