The Siella LED with UGR22 has proven itself in office environments with high energy efficiency, simple installation, pleasant light and low investment costs. TRILUX has now expanded the Siella LED product range with a further version. The Siella LED with UGR19 has been specifically developed for illuminating computer screen workstations in accordance with current standards. This makes it possible to implement lighting concepts for highly different office areas with UGR 22 or UGR19 with just one product range. This not only simplifies planning and enables economic implementation but also creates a uniform ceiling appearance. In total, this makes the series an ideal standard solution for modern office lighting.
