We forget just how painfully dim the world was before electricity. A candle, a good candle, provides barely a hundredth of the illumination of a single 100 watt light bulb.
With our new LED lighting, our cleaning lady actually complained that she has to spend extra time cleaning the kitchen and media room, because she can see dirt that the other lights never showed her. Due to her efforts, the floors and walls are a lot cleaner. Thanks! – Bradford W., Homeowner
