A three-sided triangular wall installation made from cardboard, Primary explores the three primary colours of light - red, green and blue, with the structure designed to fragment the light and demonstrate how coloured light is mixed.
"For this project I needed intense colour and absolutely pure light," explains Talbot. "The installation is purposefully designed to break up light into many shadows but unless the light source was completely even, the effect and the magic would have been lost. I needed a smooth and colour-rich shift between primary colours, so I chose the Philips Selecon PLprofile1 LED luminaires. I was then able to illuminate all three sides of the structure and create a moving and immersive environment for the audience."
The PLprofile1 is an innovative combination of LED source technology and precision optical design, with a key benefit that it is no longer necessary to change lamps or colour filters. The luminaire's single source RGBW LED chip delivers limitless colour mixing capabilities and variable colour temperature, and is a homogenised, fully mixed light that prevents multiple colour shadows.
Talbot mounted one PLprofile1 luminaire to the ceiling of the gallery and two on the floor on each side of the structure, equally spacing them from the central point of the installation in order to generate a uniform shadow effect. The three luminaires were then custom programmed through a ten-minute light show to demonstrate the colour mixing of the shadows and various different moods.
"It was integral for this project that the triangles to appear to glow," says Talbot. "This meant I needed a luminaire with the ability to shape the beam to precisely the edge of each triangle as any spill light would detract from the effect. The PLprofile1 luminaires delivered a perfectly defined beam, even at their widest beam angle of 44ยบ, which was ideal for lighting the large structure from a relatively short throw distance."
Talbot is currently talking to different lighting festivals around the world to find the right space to exhibit Primary again.
