1. Color Temperature
Color temperature is a unit of measurement for the color components contained in light, generally expressed in Kelvin (K). Generally speaking, the lower the color temperature, the warmer the light source, and the higher the color temperature, the colder the light source.
Therefore, when choosing lights, you should also choose the appropriate color temperature lights according to your needs.
- Warm light: <4000K, such a light source is warmer and can relax people;
- Neutral natural light: 4000-6000K, such a light source is clear and refreshing, which will make people feel bright;
- Cold light: >6000K, such a light source will have a serious and calm feeling, which is more suitable for office places or occasions that require seriousness.
It should be noted that blue light sources should not be used. This light source is more harmful to the eyes and is generally not recommended for use at home or live broadcast work.
2. Illuminance
Illuminance is the luminous flux received per unit area, which can be understood as how much light is obtained per unit area. It is generally expressed in units of Lux.
Different types of lights have different luminous efficiencies. It should be noted that high power does not mean high brightness.
Generally speaking, if it is used for live broadcasting, maintaining an illumination range of 250Lux-500Lux can meet the needs of work.
3. Color rendering index
The color rendering index (CRI) refers to the ability of a light source to restore the visual perception of an object under sunlight. It can be simply understood as the degree to which light restores the color of an object.
The higher the color rendering, the closer the color rendering index value is to 100, the stronger the ability to restore the color of the object, and the easier it is for the human eye to distinguish the color of the object.
CRI is a measurement method for color recognition compared with a standard light source (such as daylight). CRI is a universally recognized metric and the only way to evaluate and report the color rendering of a light source.
Generally speaking, the color rendering index of natural light is 100. For outdoor lighting, a color rendering index greater than 65 is sufficient, but when used indoors or at work, a color rendering index greater than 80 can meet lighting needs.
4. Summary
There are many different types of lights with different uses on the market.
We can refer to these key indicators and choose the right lights according to our needs. For example, our oldshark live selfie light has a circular design that makes the light more uniform.
At the same time, there are three color temperatures that can be adjusted to meet the different needs of different occasions.
Combined with our adjustable bracket, it makes your live broadcast or shooting easier. Let's take a look now!
