According to the U.S. Department of Energy, Americans stand to save $450 million in electricity costs a year if they switched to LEDs.
Of course, not everyone has warmed to the lighting tech. In this Wall Street Journal piece, the author discovers that some traditionalists can’t get past the cold, artificial lighting cast by some LEDs. But that’s not putting a dent in their growing popularity.
Part of the reason is a healthy drop in prices. A starter, 35-light set from Lowe’s can be had for under $4.00. Compare that to 2005, when early models cost about $15. And manufacturers are getting better at mimicking the look of incandescent bulbs so that decorators can achieve the same look minus the hefty electric bill.
