Two separate circuit boards each running six LEDs (the middle rows of both boards are empty) are positioned alongside each other. Notice the cranked bracket adaptor fitted - the sharp tilt of the majority of Chesterfield's hockey stick columns meant that, whenever an LED lantern was fitted in place of a SOX lantern (for example), the strong directional white light emitted would shine directly into the front windows of any neighbouring properties, potentially causing a nuisance. Although this is obviously not an issue on an industrial estate, an adaptor was still fitted here, in order to assess its own effectiveness.
