Good lighting promotes a sense of wellbeing, boosts performance – and saves energy. Obsolete lighting systems do not. Where new lamps or luminaires improve visual ergonomics and reduce energy consumption, the financial outlay is not just a sensible investment in the environment; it is a profitable move in every other sense as well.

Generally speaking, the money invested is quickly recouped through lower electricity costs. If maintenance and disposal costs are also factored into the equation, the result is even more positive. What is more, optimised lighting saves innumerable tons of CO2 , so it helps mitigate global warming.
