Let's learn more about how to calculate the number of fill lights for plant walls The first step is to generate a light intensity illuminance of at least 900lx by increasing the number or power of the lamps.
For the 35W forest box plant fill light, the test report indicates that the luminous flux is 2286lm, which can be used to fill the light for the plant wall of 2 square meters, about 1143lx. Considering that the shape of the spotlight on the plant wall is an oval area, the statement that each lamp can fill the light for the plant wall of 2 square meters is not very accurate. This rule is applicable to the plant wall of only 1 meter wide.
Considering that the light intensity will weaken with the increase of the distance of the light source, and the influence of the luminous angle, the illuminance far away from the central area of the illumination will also be less than 1000lx, so if the width of the plant wall is about 1 meter, we also suggest to use 2 lamps, or add 1-2 low-power plant lamps on both sides.
