LED light bulbs

I got my first LED light today for inside the house, I placed it in one of our ceiling fans. It claims to use only 2 watt instead of our 10-13 watt fluorescent light bulbs. They are prized pretty high, but according to the package last around 5000 hours more than a fluorescent bulb. I figured to change out seven light bulbs. My savings will be around 28 dollars on electricity a year.
