Economical LEDs. Switch Bulb Co. says its new LED replacement bulbs combine the color and dimmability of incandescents with the efficiency and longevity of LEDs at an affordable price — $20 per bulb. Current choices include 40W, 60W, 75W, and 100W equivalents, all available in neutral or warm white. The company also claims that the bulbs are 100 percent recyclable.
