Cu-Beam™ Suspended Up-Light
Verified by manufacturer 10 months ago
Sleek, suspended up-light, providing an ultra-wide distribution of powerful, dimmable ambient illumination.
Application
Suitable for lighting open spaces such as atriums, foyers and offices.
Description
Sleek, suspended up-light, providing an ultra-wide distribution of powerful, dimmable ambient illumination.
Features and benefits:
- Exclusive toroidal optic with ultra-wide 160° distribution for shallow mounting height.
- Wide and even distribution of light across the ceiling for even ambient lighting.
- 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 down-light or as with dual LEDs (both specified separately).
