Cu-Beam™ Suspended Down-Light
Application

Suitable for indoor lighting task surfaces such as meeting tables and office desks.

Description

Sleek, suspended down-light providing a controlled pyramid pool of powerful, dimmable illumination.


Features and benefits:

  • Sintered copper heat pipe technology creates a highly effective cooling system, meaning each light can use a single high-power, high-efficiency chip on-board LED (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 optic 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.
  • No flicker or glare.
  • Also available as a suspended up-light or as with dual LEDs (both specified separately).
