Downlights are made with plant polymers
A range of surface and pendant downlights printed from plant polymers has been unveiled by UK firm LumiAdd.
The variants are an addition to the Heilis family of 3D printed, plant polymer luminaires.
The series blends unique finishes, sustainable materials and flexible installation options.
The lights come in 180 RAL colours or wood, stone effect, and natural options made by incorporating reclaimed waste materials. The company says the possibilities for customisation in form, finish and texture are ‘endless’.
The LED drivers that can be remote, integral or integrated into the ceiling rose for the pendant versions.
LumiAdd says to ensure continuity within a project, the performance of these variants of the Heilis family match that of their recessed counterparts. They feature of high efficiencies of >100llm/cW at Ra90 and a colour temperature of 3000K. A variety of beam angles and colour finishes is available is three body sizes; 65mm, 89mm and 111mm.
LumiAdd recently won two prestigious Build Back Better Awards, a Gold and Green, for its Lania track-mounted spotlight, which is partially made from spent coffee grounds.
Combining the coffee with plant polymers from renewable sources like sugar cane, enhances the environmental value and reduces fossil fuel use.
LumiAdd has printed products using other waste streams, including re-claimed oyster and scallop shells, spent grain from beer production and waste from chocolate production.
LumiAdd uses plant-based polymers to 3D print luminaires. It says that the plant polymers it uses are significantly more sustainable than conventional materials currently used in the lighting industry.
They produce 33 per cent less Co2 emissions than petro-chemical polymers and 97.5 per cent less Co2 emissions than aluminium.
3D printing on demand results in zero waste. LumiAdd products achieve the highest TM66 (CIBSE Circular Economy Assessment Method for Manufacturing) category of excellent circularity. LumiAdd also offers a buy back scheme to support the return of LumiAdd luminaires at the end of their first use to ensure they can be reused again.
