Cu-Beam™ Duo Suspended Light

Provides a wide and even distribution of up-light across the ceiling for even ambient indoor lighting.


Combined up and down light with full flexible control. Alters to suit changing needs throughout the day. 

Features and benefits:

  • Sintered copper heat pipe technology creates a highly effective cooling system: each light uses two high-power, high-efficiency chip on-board LEDs (CRI: 80, minimum; two-step binning).
  • This light source, combined with a custom-designed polymethylmethacrylate (PMMA) lens, delivers optically efficient, precisely controlled illumination.
  • The cooling system prolongs the life of the LED, providing long-lasting performance and colour stability.
  • Exclusive rectangular distribution down-light with adjustable trim blades for optimum framing and glare control.
  • Power through suspension cable.
  • A customized long-life Digital Addressable Lighting Interface (DALI) driver, with additional heat sinks and high-grade capacitors, is engineered to last as long as the luminaire.
  • Custom-built driver compatible with DALI, 1–10 V, 0–10 V and PWM protocols.
  • No flicker or glare.
  • Also available as a single LED suspended up-light or down-light (both specified separately).
