What are some of the advantages of having a light meter?
● Compact Size, Light Weight
The opportunities for use of illuminance meters are very wide, and the timing of use is often in different places. Therefore, the first prerequisite for a portable illuminance meter is its small size and light weight.
● Accuracy﹝Accuracy﹞
Whether a light meter is good or bad has an absolute relationship with its accuracy. Of course, it is also closely related to its price. Therefore, it is necessary to buy a high-accuracy illuminance meter at a reasonable price. Generally, it is appropriate to have an error of no more than ±15%.
● Color Compensation﹝Color Compensation﹞
The types of light sources are all-encompassing. Some focus on red high-pressure lamps with longer wavelengths, or blue-violet lamps with shorter wavelengths such as Daylight fluorescent lamps. There are also evenly distributed ones such as incandescent light bulbs. The same illuminance meter may have slightly different sensitivity to different wavelengths. are different, so appropriate compensation is necessary.
●Cosine Compensation﹝Cosine Compensation﹞
As we all know, the brightness of the illuminated surface is related to the incident angle of the light source. In the same way, when measuring with a light meter, the incident angle of the sensor (Sensor) and the light source will naturally affect the reading value of the light meter. Therefore, whether a good illuminance meter has the function of cosine compensation cannot be ignored.

In order to make our living environment more conducive to our health, the use of light meters has become our first choice. But how to choose a light meter that suits you? An illuminance meter (or lux meter) is an instrument specifically designed to measure luminosity and brightness. Generally we should consider the following points when purchasing:
The unit of illumination is one lux (LUX), which uses numerical values to express the appropriate light intensity in these places to ensure that it can adapt to various environments. In daily life, all environments such as offices and factories have their own "suitable illumination". Once the illumination Insufficient or excessive illumination can lead to misunderstandings, low operating efficiency, and fatigue, which may lead to reduced vision. When the illumination is moderate, work efficiency can be improved and work safety ensured. For this reason, it is important to pay attention to lighting management.
