ALD Lighting Solutions was asked by a local M&E consultant to develop a continuous LED trough system that would be surface or pendant mounted to ensure each room of varing ceiling heights would look identical. We used a mixture of 4ft and 5ft bodies, the surface mounted version gave a totally direct light while the pendant version was direct/indirect. The Indirect portion allowed a wide angle lens to wash as much light uniformly onto the ceiling. We also incorporated all the emergency standalone LED’s within the dummy sections along with the DALI programmable sensors.
