Changing light fittings from old types to modern LEDs can save approx. 50% of energy. In most buildings there is some form of vapor lamps, fluorescent tubes or halogen and although there is a good light yield from them, LED has gradually become so much better. Livestock rooms, living rooms and greenhouses are appropriate places to change.
New fittings have an additional cost, often considerably more expensive than traditional fittings. This must be paid for by savings in consumption.
The lifespan must be long, but it is also important that the quality is good enough. With new lighting control, increased production can also be achieved, for example in dairy barns.
