1) High light efficiency

Light efficiency, that is, luminous efficiency, refers to the ratio of the luminous flux emitted by a light source to the electrical power consumed. It can be expressed in lumens per watt or LM/W (luminous flux: refers to the amount of light emitted by the light source per unit time, which is an important indicator of the brightness of the lamp, expressed in LM.) Compact fluorescent lamps are compared with ordinary bulbs. The luminous efficiency is increased by about 5-6 times. For example, the luminous flux of an 11W energy-saving lamp is equivalent to a 60W ordinary incandescent lamp.

(2) long life

The so-called life refers to the cumulative time of a finished lamp from ignition to "burnout" or lamp operation to any requirement below the life performance specified in the standard. A typical incandescent bulb has a rated life of 1000 hours, and a compact fluorescent lamp typically has a life of 5000 hours.

(3) good color rendering

A variety of similar light sources will display different light colors. We use the CRI (COLOR RENDERING INDEX) to determine the range from 0 to 100. The color of the incandescent lamp and daytime sunlight shows an index of 100. Displaying the level of the index directly reflects the color rendering of the light. The higher the color rendering index of the light, the more the true color of the object under its illumination is reflected. On the contrary, the color of the object will be distorted. In general, as long as the color rendering index of light is greater than 75, the color of the object can be truly reflected without distortion.
