Cu-Beam™ suspended lights provide powerful light, precisely where you need it. Heat pipe technology creates a highly effective cooling system, meaning each light can use a single high-power, high-efficiency chip on board LED. This single light source,
combined with a custom-designed PMMA lens, delivers optically efficient, precisely controlled illumination.
The cooling system also prolongs the life of the LED, ensuring long-lasting performance and colour stability. The luminaire is supplied with a customized DALI driver, with additional heat sinks and high-grade-capacitors.
