Did you know that dimming a traditional incandescent bulb just 15 percent is hardly noticeable, yet can save you 15 percent in electricity costs and triple the life of the bulb? That’s pretty cool, and so are Lutron’s new Maestro and Meadowlark eco-minder switches that bring some style to light dimming. The eco-minders turn small LEDs on their panels from red to green when you’re saving at least 15 percent. The Maestro eco-minder ($45.50) also has a customizable, delayed, fade-to-off that lets you leave the room or get into bed before the lights go out. The Meadowlark ($24.80) has a slide dimmer and a green LED that brightens as you’re saving more. Lutron Store
