Summary[edit | edit source]
This Libre Office (free software) worksheet is a quick tool for determining if you should switch from incandescent to LEDs.I erred on the conservative - e.g. the LED will output more light. Most spaces are over lit - so you can probably get away with less. As you can see the return on investment for moving to LEDs is substantial in most applications.
Please note that the ROI calculation is an approximate - based only on payback time and does not take into account the lifetime. To do it correctly see information here:
