Laser light bulbs?

Recent work at Sandia Laboratories may lead to a review on the use of lasers as well as LEDs for higher amperage illumination applications because of human preferences. Volunteers were show a test-box scene illuminated via different light sources. Tests showed that there was a statistically significant preference for the diode-laser-based white light over the warm and cool LED-based white light, but no statistically significant preference between the diode-laser-based and either the neutral LED-based or incandescent white light.
