Many people perpetual lamp bought all kinds of so-called plant growth lights. After they are used, they say that perpetual lamp is useless. What is the real situation?
Taking the aquarium as an example, we have strict standards for the illumination needed by sea creatures. Generally, 1L water is required to correspond to 1W lighting, which is not very scientific. In fact, it should be based on the lumen illuminance. For example, in most cases, the illuminance of LED under the same wattage will be about 1.5 times that of halogen and three primary colors. Let's talk about the wattage for the convenience of description. From the experience of cultivating sea creatures, if we fail to meet this standard, half of the illumination is not equal to half of the effect. Basically, we can say: no effect! So, when you look at those so-called plant growth lights online, you can see that many of them are 5050 patch LED (shopping mall jewelry lantern), and even a single perpetual lamp has no 1W! It looks like a huge luminous area of lamp beads, which is dazzling. In fact, the power is only 1-3W in many cases! It is conceivable that the effect is limited.
In fact, the students who have many years of experience in raising too much meat all know that the effect of direct high-intensity sunlight in just a few hours a day is far more than the scattered sunlight of more than 10 hours a day! Therefore, if you want to make up the effect of light, power is absolutely an important factor to consider!
