LED lighting lamps and lanterns of common parameters are as follows:
a, the luminous flux LED lighting lamps and lanterns

Also what is the color of the illuminant, we according to the colour of the distinction between the color temperature.
color temperature value with K showed that the light source color temperature is different for users, light color is different, the feeling is not the same: refer to the above color temperature contrast table will have a very intuitive feelings.
three, LED lighting lamps and lanterns of color rendering
actually is a more professional color parameters, the extent of the light source to the objects themselves colors is called color rendering, also is the degree of color vividly.
