LED Calculator makes it possible to calculate electric energy consumption of illuminants in your apartment, house or office. The app calculates annual savings in case you change existing lighting with LED bulbs. The last step in the app is directly connected with the company Elektro Kovačič d.o.o., which enables a simple and reasonably priced replacement of existing bulbs with LED bulbs. *The offer that you make in the app and send to the company is non-binding, only informative.
