For concerns over the environment and energy costs, new laws have made compact fluorescent bulbs the standard in American households.Now, LED light bulbs offer even better benefits.But will the cost be too much?Fox Mankato's Ryan Gustafson has the story.A light-emitting diode isn't exactly a new technology - but it has just recently entered the lighting sector.And the stores are excited for its potential.Jeremiah Myer says, "Incandescent bulb will last us about 1,400 hours. This right here will last us 10,000 hours - a significant increase. This right here will last 17,000 hours if you break that down, that's going to be about 33 years of time. A very long time."The sticking point for many will probably be the price.The LED light on display at Home Depot costs over fifty dollars.John Hutchens says, "They're still in the experimental stage, getting that watt to lumens ratio up. But we're about a year or two away - we're starting to see them hit the markets now."A similar pricing situation came about when CFLs first hit the market, as the new technology had to find its niche.Those we talked to expect LEDs to follow a similar route, though they do not expect the change to occur overnight.Hutchens says, "It depends on what you're looking for. If you're looking in the commercial area, or re-lamping your house - the cost per dollar is going to be a little bit prohibitive."Myer says, "Do we want to put them throughout the hallways and in the garage, down in the basement? Maybe not. But right now, picking the places that we put them in, it's a good value for our customers."One area they definitely recommend LEDs for: Christmas lights.And both Benco and the Home Depot will be offering deals for trading in incandescent holiday lights for LED versions.In Mankato, Ryan Gustafson, The Fox Mankato News At Nine.
