Dufour

The Dufour UGR is a round LED high-bay luminaire made of die-cast aluminium for low-glare illumination of halls and industrial areas. The family comprises three power levels from 100 to 200 W with a luminous flux of 14'000 to 28'000 lm at an efficacy of up to 140 lm/W. The integrated optic achieves a glare rating of UGR < 19, making it suitable for workplaces with high visual demands. Thanks to its powder-coated housing and an operating temperature range of up to 50 °C, the Dufour UGR is also suitable for warm hall environments.
