EcoBulb

EcoBulb is a simple and straightforward application you can use to compare different light bulbs for energy saving. It gives you some general statistics about incandescent light bulbs, light emitting diodes (LEDs) and compact fluorescent lights (CFLs).

The software product features a minimalistic window with a neatly structured layout. It's actually packed in a Modern UI and optimized for machines with touch support, such as tablets and notebooks, as long as they're running Windows 8, 8.1 or 10.

Since it's trusted by Microsoft, it can be downloaded and installed from the Windows Store.

The main window has white and green tones, where you can select the bulb type by clicking a dropdown list on the left to choose from incandescent light bulb, LED and CFL.

Depending on your selection, the tool shows analysis details to let you know how much energy and money you save using a specific type of bulb, compared to the other two (including annual cost).

To tweak the analysis, you can change the wattage of the bulb, number of bulbs (from 1 to 50), daily average hours of usage (from 1 to 24), as well as electricity cost (number of dollars per kWh - kilowatt hour).

The application doesn't have options for copying all this information to the Clipboard or saving it to file. However, you can take a snapshot and send the image to one of your Modern UI apps to save it in this way (like Microsoft OneNote).

All things considered, EcoBulb offers a simple calculator for finding out how much energy and money you would save by using incandescent light bulbs, LEDs or CFLs. Unfortunately, it implement support for just one currency (dollar).
