Let's shine a spotlight on LED lighting for a moment. At Touchstone we use built-in LEDs in our LCD monitor controller boards, and produce power supply units that are LED current-controlled. But as far as using LED bulbs for home or business lighting, many people don't know that there are no white LED chips; “white” light is created using multiple colors. And most current LED bulbs use blue LEDs to excite a phosphor that then glows white. These bulbs produce no violet or ultraviolet light.

How does this relate to... laundry soap? Here's how: Detergents contain optical brighteners that don't work well under these LED bulbs. Here's a really interesting article that describes why you might not see "bright white" quite as often, as incandescent and fluorescent light bulbs are increasingly replaced with LED bulbs.
