What is the difference between popular science LED floodlight and LED floodlight?

Floodlights and floodlights are not the same kind of lights.

A floodlight is a lamp that specifies that the illumination of the illuminated surface is higher than the surrounding environment. Also known as spotlight. Generally, it can aim in any direction and has a structure that is not affected by climatic conditions. Mainly used in large-scale operation fields, such as mines, building outlines, stadiums, overpasses, monuments, parks, flower beds and so on. So almost all outdoor large-area lighting lamps can be regarded as floodlights. The angle of the beam emitted by the floodlight is wide or narrow, ranging from 0 to180, and the particularly narrow beam is called a searchlight.

Floodlight: English name: floodlight? The floodlight is a kind of point light source that can irradiate uniformly in all directions, and its irradiation range can be adjusted at will, which is represented as an octahedron icon in the scene. The floodlight is the most widely used light source in rendering, and the standard floodlight is used to illuminate the whole scene. Multiple floodlights can be used in the scene. In order to produce a better effect, the light bulb for shooting is put into a large reflective umbrella and used as a high-brightness diffuse light source. Although it is indispensable for indoor lighting, it is also one of the light sources with good lighting effect for ordinary amateur indoor photography.
