Lecture theatre, University of Buckingham

We were called in to investigate problems that the University was having controlling the lighting in the lecture theatre. The lights were low-energy, dimmable fluorescent downlights. The users of the room were finding it difficult to use the system and were reporting low lighting levels and system instability. We investigated the problem and found it to be caused by an incompatibility between the dimmers and the ballasts in the luminaires. After analysing the technical and cost implications of possible solutions we recommended that the existing ballasts be replaced and a new interface modules added to the existing dimmer system to control them. The modifications were carried out during a University vacation and the system is now producing the required quality of light and ease of operation for the users.
