New York 2016: US atelier Ladies & Gentlemen Studio has designed a series of lighting pendants with glass spheres that change colour once the light is turned on (+ slideshow).

Designed for New York store The Future Perfect, the Equalizer lights are made up of customisable metal frameworks and LEDs encased within spherical frosted glass balls.

The lamps originally featured grey-tinted glass, but artist John Hogan has handblown a set of coloured versions tinted with a special glaze.

"All of the glass in the lamps are sand blasted and oiled to give the surface effect and to diffuse the LEDs," Hogan told Dezeen. "They involve a specialised, colour-changing glass."

"The colour is achieved by exposing the raw colorant to a rich flame right after application," he said. "The colorant is then coated and diluted with a layer of clear glass which creates the final density and fade in the lamp."

The metal framework on both editions is available in three finishes: dusty blue, champagne bronze and dark bronze.

"The collaboration activates Hogan's in-depth exploration of the glass medium and how it relates to Ladies & Gentlemen Studio's experiments in lighting, form and spatial experience," said The Future Perfect.

Designed to be scaled and composed according to different spatial constraints, the system can act as a divider in open-plan spaces.

Although the majority of the pieces within the collection are hanging lights, prototypes of floor standing, table and reading light variations are also on show at The Future Perfect store, 55 Great Jones Street, from 6 May 2016.

The preview is one of the highlights of the broader NYCxDesign festival taking place from 3 to 17 May 2016, where Lambert & Fils is debuting a collection of pendant lighting and Carl Hansen & Søn is launching two chairs by Modernist designer Hans J Wegner.

Ladies & Gentlemen Studio was founded in 2010 by designers Dylan Davis and Jean Lee, and operates between Seattle and Brooklyn.

The bi-coastal atelier previously teamed up with John Hogan during last year's NYCxDesign festival to create an installation at Sight Unseen's Offsite exhibition.
