LED Switch is a simple app designed to show how much you could be saving by switching to LED light bulbs.
You can do a quick check by inputting the bulb type you will be replacing and the number of bulbs you will replace, or you can add optional information such as electricity cost, the time the bulb is on for and the cost of the LED bulb replacements to get a more individual result.
The result will give you an approximate current usage and cost, along with the usage and cost of using LED bulbs instead, as well as your potential savings and payback time (time taken for savings to equal the initial investment).
