The Radial system is the result of close working relationship between Foster + Partners and iGuzzini and provides a wide range of customised lighting solutions. The fittings were developed to emit both indirect and direct light and are precisely detailed to provide a versatile luminaire with a minimal contemporary design. The lightweight illuminating body with a round 10 centimetre shape is available with up-light, down-light and direct/indirect light emissions. The range features two versions – suspended and wall-mounted – and both are made of die-cast aluminium. While the asymmetrical diffuser is made of super-pure aluminium, the soda-lime glass in the indirect/direct-light version also has a diffusing lower section. Special attention to technical details and the use of metal-halide, halogen and compact fluorescent lamps ensure a very high light output with low management costs.
