How to distinguish between tree lights and LED flood lights?

The so-called tree light, as the name suggests, is mainly used to brighten green belts, street trees, garden landscapes, etc. The tree light is a low-power flood light, which is the kind of LED flood light that we usually project under the tree at night to green the landscape lighting and make the tree look beautiful, which is similar to the wall washer.

LED floodlights are lamps that make the illuminance of the designated illuminated surface higher than that of the surrounding environment. Also called floodlights. In general, it is capable of aiming in any direction and has a structure that is not affected by climatic conditions. Mainly used for large-area mines, building outlines, stadiums, overpasses, monuments, parks and flower beds, etc. Therefore, almost all large-area lighting fixtures used outdoors can be regarded as floodlights. The beam angle of the spotlight is wide or narrow, ranging from 0° to 180°, and the beam with a particularly narrow beam is called a searchlight.

The iso-intensity curves of such lamps are concentric circles. When this form of floodlight is illuminated by a single lamp, an elliptical light spot is obtained on the illuminated surface, and the illumination is uneven; but when multi-light illumination is used, the light spots are superimposed on each other, which can produce a satisfactory lighting effect. For example, hundreds of rotationally symmetrical floodlights are commonly used in stadiums, which are installed on high towers around the stadium to obtain high illumination and high uniformity lighting effects.
