BAND-OH!

Delta Light > Functional light

Layers of light Shape your wall into a piece of art. The layers of light generated by Band-Oh! provide a sense of depth onto the surface its being installed on. The light not only hits the wall for a V-shaped down-up light effect, it also creates a play of light on the fixture itself. the design of Band-Oh! is made out of several shells above each other. An overlap between 2 layers shieds the light source, while its openess leaves space for reflected light to escape. The result is a soft glow of light on the inner shell of Band-Oh!, generating an optical illusion of the outer shell freely floating around it. While the double finish in two shades of black - structured matt and shiny Piano Black - enhances the layered feeling, the finish in Brushed Old Bronze gets an extra layer of richness thanks to the soft glow lighting it up.

IMAX

Delta Light > Functional light

Where the initial evolution in LED and optics focused on better output, smaller chips and longer lifetime, the second evolution is again shifting to user comfort with more precise optics and better light control. As the purpose of the iMax II family is to provide the best visual comfort to the user - thanks to its recessed LED engine - this range is perfect to build further on this evolution: improved efficiency, improved beam angles and the possibility to combine all versions as they use uniform LED engines. The iMax II range combines premium LED engines with precise optics, delivering high performance, maximum efficacy and high quality illumination. iMax II is using lenses out of plexiglass HW55, a material able to withstand high temperatures and allowing lumen packages up to 2000lm. Next to the high output, the lenses allow for a perfect control of the beam angle and a high uniformity on the light emitting surface, which results in reduced glare. Furthermore, if a different beam angle is required, the lenses can easily be interchanged. To offer even more flexibility and design freedom to the lighting designer, a range of light refining accessories is available to alter the light effect to the specific needs of the setting. A honeycomb to further minimize the direct glare from the light source, a sandblasted glass to create a diffuse general light effect and 3 specific lenses to either create a more oval or a wider light distribution or to smoothen the edges and create a softer transition.

XY180

Delta Light > Functional light

‘XY180’ is a 3-piece lighting collection designed by OMA. The collection was inspired by a fascination with point, line and surface; key architectural elements. The floor, wall and ceiling lights are meant for individual and shared workspaces, but can also be applied to domestic and public interior spaces. The line uses precise geometric dimensions while the base elements - which include tube lights and a spotlight in either a discreet 3,9W or a powerful 7,1W - can be combined with a hinge to generate countless lighting conditions. As individual components, each part is familiar. When assembled however, they can take on unpredictable and asymmetrical positions. The tube lights create diffuse ambient lighting, while the spotlights provide focused lighting. By exposing the light and allowing it to pivot, the fixture becomes the main feature as it shifts into multiple configurations; a product that contributes to the creation of space, not only by the light it emits, but also by its physical presence.
