How To Identify The Quality Of LED Spotlights
The light in nature is scattered aimlessly and has no direction. The same is true of the light sources invented in the early days of human beings, which spread from a luminous point to the surrounding. Later, people added a cover to the light source, and the light had direction and irradiation range according to people’s intentions. Street lights and table lights are typical applications for controlling the direction of light. Of course, this is only a simple control of the direction of light. Until the emergence of LED spotlights, the control of light can really be done according to human intentions. Therefore, LED spotlights are becoming more popular in modern continuous lighting, and the application scenarios are becoming more popular and complicated. LED spotlights are the most widely used now. Due to the confusion in the LED market and the lack of understanding of LED video lights, there is a lack of methods for how to tell the quality of LED spotlights. Below, I will share with you 3 methods to identify the quality of LED spotlights.
The shape of the spot, as the light of the LED spotlight projected on the plane, is the first standard line for identifying the light quality of the lamp. The excellent light spot directly improves the excellent visual experience of the item. The appeal spot is clear, and the extended fill light is more natural. The LED panel light distribution of the reflector is uniform, the center intensity gradually weakens outward, while the halo is natural and comfortable, which is a more comprehensive light spot effect. The light distribution is uneven, serious dark spots appear, the light utilization rate is low, and the performance of the illuminated items is poor. The halo border has multiple shadows, the light spot is rigid, and the stray shadow and virtual shadow are obvious.
The color rendering index, referred to as the CRI for short, is the color rendering ability of the light source to the object, usually referred to LED photography light, which is obtained by comparing the appearance color of the object with a reference or benchmark light source (incandescent light or painting light) of the same color temperature. The spectral content emitted by the light determines the light color of the light source, but the same light color can be formed by many, a few or even only two monochromatic light waves, and the color rendering of each color is also very different. Light sources with the same light color will have different spectral compositions, and light sources with wider spectral compositions are more likely to provide better color rendering quality. The CRI is still the common method for defining the color rendering evaluation of light sources.

Light color is what we usually call color temperature (correlated color temperature). Color temperature is a physical quantity used in lighting optics to define the color of a light source. That is, when a black body is heated to a temperature, and the color of the light emitted by it is the same as the color of the light emitted by a light source, the heating temperature of the black body is called the color temperature of the light source, referred to as color temperature, and the unit is expressed in K . The led continuous lighting with low color temperature is yellowish, such as incandescent lamp, about 2800K, and the light with high color temperature is more blue, such as purple light, above 9000K.
