Managers at Lowe's on Range Line in Joplin say many people are purchasing the 60 and 40 watt incandescent light bulbs before they're phased out.
Production of these popular bulbs will fade to black on January first.
Federal legislation requires all light bulbs to use 25-percent less energy by 2014.
Lowe's employees say customers seem intimidated by new generation bulbs like LED's which meet the new requirements.
"They're quite a bit more expensive but what a lot of people don't realize is that they're going to last about 10 to 15 years where as incandescent bulb will last about one year so there area lot of different features that an LED provides that some customers are just not aware of," says Lowe's Assistant Manager Michael Gage
Lowe's has a three-month supply of incandescent bulbs and expects them to fly of the shelves within that time frame.
