I pride myself in producing the most realistic lighting designs within the timescales and budgets afforded to me. I believe that the more realistic that you can make a room within a scheme, the more accurate that the design will be; and reflected in the results.
Many people who need a lighting scheme designing generally start by asking a contractor to organise this; and then this request is passed along the supply chain until it reaches a lighting manufacturer who will generally produce a scheme for free. So why pay a consultant to produce one?
