Calculation example: Production hall at TRILUX in Arnsberg with approx. 2,000 m² with a previous stock of 328 E-Line luminaires T8, 1 x 58W, VVG (21,648 W), which were replaced by E-Line Next Active luminaires, 6,000 lm, 39 W (12,792 W). In line with Human Centric Lighting (HCL), the new lighting system enables the colour temperature to be adapted to the course of the day of natural light (circadian progression) and an increased lighting level to be set if required.

The adjacent calculation is based on 4,000 operating hours per year, with controlled operation at 500 lx. The maximum available illuminance of 880 lx can be called up as required.
