Kaleidoscopia sees two of Broom's most-used design elements – light and reflections – combined to create a hall of mirrors, with an assemblage of lamps at its centre.
The installation is made up of just 17 individual lights and two mirrors, but a cascade of reflections creates the appearance of one large chandelier formed of more than 200 lights.
"It is actually a fairly uncomplicated design using mirror, black carpet and clever angles," Broom told Dezeen.
"But the overall effect is very extensive, giving the impression of a super-sized lighting installation. It's like stepping into a Tardis."
Broom's Orion lights are combined in different colour-ways and positions to recreate the tunnel shape of a kaleidoscope.
Each light consists of a glass and gold-coloured polished steel sphere mounted on a contrasting tube in the respective other colour.
In this constellation, the modular units are arranged both vertically and horizontally to form pillars and sun-like rays radiating from the centre of the piece.
With Kaleidoscopia, Broom hopes to take visitors on a "journey of altered perspectives," hypnotised by endless reflections, optical illusions and a dreamy electronic soundtrack.
"I wanted it to be imposing yet intimate, that same kind of feeling you get when you approach the altar of a cathedral, or like a child going into a hall of mirrors for the first time," said Broom.
For previous iterations of London Design Festival, the lighting and furniture designer has made use of mirrors to transform his flagship store into a double-image living room and a Yamoi Kusama-esque hallway of pendant lights.
The London Design Festival is running from 14 to 22 September, with a range of installations, exhibitions and events on offer across the city.
