This St Cyril & Methodius student switched out a working incandescent lightbulb for an energy efficient CFL! She knows that a 13-watt CFL emits as much light as a 60-watt incandescent. Plus, it doesn't get as hot and it can last up to 10 times longer! Cool-running CFLs and ceiling fans are great summer items to have to keep the inside of your home cool and breezy!
