Good point – I was imagining something with directed beams, but looking it up the idea does seem to be just to spread light everywhere. I'm guessing anything commercial will either use light so dim you don't notice it, or either infrared or ultraviolet, though – I suppose if it was just integrated into light bulbs that would work, as long as you want the light on (although it might still be cheaper to use a red laser with green and blue LEDs to make the overall lighting white).
