Field tests of LED floodlights exceeds expectations
R. Stahl | The cost-saving potential of eco-friendly, highly efficient LED lighting solutions compared to conventional light bulbs has come to be universally acknowledged and appreciated. But there is some uncertainty around the performance of LED lights in real-life situations. For this reason R. Stahl surveyed LED, HST and HIT lighting set-ups in a true-to-life experimental test field. A series of tests was conducted to determine the illuminance provided by the various lighting solutions. In each of the three set-ups, the lighting rigs were mounted on a 4.3m-high scaffold above the ground, with measurements taken over an area below of 10m by 13.7m. R. Stahl compared expected values using R. Stahl ezyLum light plann ing software with the actual measured values with the aim of ascertaining how dependable such calculations really are for light planning, i.e. whether all lighting systems – and especially LED floodlights – truly perform as effectively as predicted by light planning software tools.
