  • The limited market penetration suggests that ignoring the differences and claiming universal compatibility will lead to consumer rejection. Politicians should develop the power of persuasion rather than the imposition of regulation.
  • In new dwellings domestic lighting suffers from inadequate installation. The formula is based upon the minimum number of lighting points arranged with the shortest cable runs. Consequently, lighting is often wrongly positioned and poorly controlled.
  • For some rooms, where there are fixed working positions such as kitchen and bathrooms, permanent lighting can be installed. For other rooms the lighting needs are determined by the layout of furnishings particular to a set of occupants. A more flexible arrangement is needed if the lighting is to both effective and efficient.
