Always on the lookout for better ways to measure all kinds of things, researchers have published a detailed study suggesting an "elegant" improved definition for the standard unit of light power, the optical watt. The proposed definition promises a more precise, less expensive and more portable method for measuring this important quantity for science, technology, manufacturing, commerce and national defense.
