Created for Swedish lighting brand Ateljé Lyktan, Halo is a round lamp made from opaque acrylic plastic that houses LEDs to create a "warm but subdued" lighting effect.
An opening at the bottom casts a stronger beam of light downwards onto a pathway. The LEDs inside are protected by a cover of hardened glass. "The light source is reset into the fixture so as not to blind at a distance," explained Borselius.
A circle of dark-coloured aluminium provides added strength around the opening, and is repeated at the top to create a cap. This cap is connected to a tubular fixing that can be used to attach the light to a pole, line or other street furniture.
Halo was designed "in order to enhance the cityscape in an authentic and natural way, while at the same time perfecting traditional street lightning," according to a statement from Borselius.
"Halo is inspired by the circle of light surrounding strong luminous bodies like the sun and the moon," said Stefan Borselius. "The faintly glowing globes turn deserted urban centres and vacant parks into inviting spaces, while the downward facing LEDs give vibrant light where it's really needed."
The lamp is available in two sizes – the larger 600-millimetre diameter version is intended for use on a tall pole or suspended from a line, while the smaller 450-millimetre model is for lower heights and can be mounted on a wall or post.
LEDs were chosen as the light source as their long lifespan means they require minimal maintenance.
"The fixture is designed from the inside, rather than from the outside. My goal has been to use a straightforward technological solution to create a functional light with its own soft character," said Borselius.
