The dots need electricity, or other light, to produce light. So something still has to be powered by electricity. How are they proposing to make tables, walls or forks glow? The forks, especially, would have to be battery-driven - very inefficient. It seems to me that a bulb is still a very convenient place to place these quantum dots; one the whole, we prefer our illumination from above us than below. Perhaps future design would include panels on a wall or ceiling wired to use them.

The article says the LED/quantum dot lights are twice as bright as "the standard 60 watt light bulb"; isn't that less efficient than a fluorescent blub (mine say they use one fifth of the energy of an incandescent bulb)? Why are these an advance on fluorescent bulbs?
