Light efficiency: The ratio of the total light flux emitted by the light source to the electrical power (watt) consumed by the light source is called the light efficiency of the light source, and the unit is lm/w(lumens/watt). Light efficiency is an important indicator to measure LED light source. The higher the light efficiency, the greater the LED's ability to convert electricity into light. Again, for the same amount of light energy, you save more energy.

Luminous flux: Luminous flux is the total energy received by the human eye from light emitted by the light source. The unit is lm. The light flux is measured by a measuring device (distributed photometer/integrating sphere). The luminous efficiency can be calculated by matching the light source power. The luminous flux can directly reflect the luminous energy emitted by the luminaires. But a higher light flux does not necessarily mean higher brightness in leds. Luminance evaluation requires many considerations, including the material of the object and the reflection coefficient.

Color temperature: Color temperature is an important parameter reflecting the color of LED light source. People have gradually changed from the earliest pursuit of high color temperature era to the pursuit of warm white, close to the natural light era. Because the high brightness of the earliest high-color temperate zone has been beaten by its dazzling cold white light, people are constantly seeking more comfortable lighting effects.
