Bringing Digital Lighting Management to the Fixture Level
Over the last year we’ve seen a move to bring lighting control to the fixture level. Many manufacturers have integrated occupancy sensors and photocells into their fixtures. Sometimes these controls are connected to a local network of lighting fixtures, but more often the integrated controls are designed to generate some energy savings by enabling bi-level switching for areas like corridors, stairwells and sometimes troffers in open offices…
