Entry Description

The award-winning D900 Cube is the world’s first square
LED downlight that produces a square-shaped light
beam. This revolutionary beam shape allows for precise
aesthetic alignment with straight-edge spaces, leading
to unprecedented efficiency in lighting design.

Enabling light to spread more evenly in a room, the D900
Cube’s square beam means fewer lights are needed than
ever before to light a space. No longer are there
overlapping beams in one area, with dull shadows in the
others, which can occur with common circular beams.
Brightgreen’s D900 Cube was designed in Australia with
the goal of creating an energy-efficient lighting solution
that not only provided adequate brightness comparable
to halogens, but also was architecturally and
aesthetically satisfying.

Operating on only 16 watts, the D900 Cube boasts a
brightness of 903 lumens, matching the light output of a
premium 50W halogen on one third of the power. Its
long lifetime of 70,000 – amounting to about 30 years of
household use – is protected by 4000 volt surge
protection and in-built thermal monitoring, which dims
the light when it becomes too hot.

The D900 Cube is so efficient that at the end of its
product life, it will have saved 2590 kilowatt hours when
compared to halogen lights – the equivalent to running
your washing machine once a week for nearly 30 years.
The D900 Cube contains no heavy metals and can be
disassembled by hand, with all parts completely

When matched with its high Colour Rendering Index (CRI)
of 90, the light quality of the D900 Cube reigns supreme
when compared to other energy efficient lighting types,
such as compact fluorescents, which have a CRI of just
50. Its high CRI allows people and furnishings to look
their best, and colours their most vibrant.
