Light that is visible to human eyes is simply electromagnetic waves whose wavelength which happens to be in the perceptible range. The unit that we used commonly to measure the energy of light is watts and the quantities we used to describe a light’s characteristics are radiometric. How light is perceived by each one of us is varied, our eyes and brain can give a different perception of a similar light‘s color and brightness. We, the human, are typically responding to light with wavelengths from 380 nm to 780 nm. After the light signal is picked up by our eyes, it gets prett...

Energy-efficient light bulbs can be far from perfect. CFLs can take minutes to achieve full brightness compared with LEDs that brighten instantly, but in tests, one LED was dim and emitted a ghastly, bluish light color, and others couldn't cast light in all directions. Consumer Reports has identified four light bulb letdowns and ways to prevent them. Dim bulbs: Opt for more lumens. Check the lighting facts label on the packages of CFLs and LEDs for the number of lumens. The higher the lumens, the brighter the bulb. Weird light color: Choose the r...
