Light Bulb Finder is a free app on Android, iPhone, iPad, iPod and Touch Mobile devices. This free app makes it easy to switch from conventional light bulbs to energy-saving ones. Just submit which fixtures and incandescent bulb types that you would like to replace, and the app finds the right style and light quality. The app can allow you to view financial payback and environmental impact of recommended light bulbs. From there you can actually make a shopping list and either buy from the app or use to purchase at a local store. This free app has been selected from the Environmental Protection Agency as the Winner of the Best Overall App for the Environment Challenge.
