East London design studio Haberdashery has created floor and table lamps with light sources that change colour as they move up and down, to resemble the rising and setting sun.
Called Dawn to Dusk, the lamps each feature a flat disc-shaped light source, which slides up and down a central black stem that is mounted on a weighty triangular base.

As the disc-shaped light source rises up the stem, the colour of the light transitions from a low-intensity red hue, through orange and warm white, to a bright white light designed to emulate the midday sun.
Controlled by hand, the light source sits in an off position when at the base of the stem.
The disc can also be rotated 360 degrees so that the lamp can be used as a forward-facing task light. Or if rotated to face the wall, it will create an ambient glow.
The lamps are controlled by custom-designed mechanical and electrical components that are integrated into the stand and head of the lamp. The only off-the-shelf component used in the design is the wall-mounted driver.
"During the development process we realised that recreating the warm hues of a sunset would look crude using existing off-the-shelf technology, so we set about developing a custom LED array, incorporating a specific red found in horticulture," explained Haberdashery creative director Ben Rigby.
"The result was a blend of light sources allowing us to create a far more satisfying deep rich red, and a more realistic transition through to white light.&...
