Many customers who have purchased LED lamp heads will find a problem, 50W is not even 30W bright, which is incomprehensible to them. In response to this problem, we can take a look.

Solar LED lights use direct current, the operating voltage is generally 12V-33V, and the voltage is constant and the current is adjustable. There are many types of chip packages for LED lamp beads, and the wattage of a single lamp bead is also divided into high power and low power. There are a single wattage of 0.3W, 0.5W, 0.7W, 1W and so on. If a single 1W lamp bead is used for the LED and the number is 30, then the full power of this lamp is 30W, so a solar LED lamp can not accurately determine the full power of the lamp based on the number of lamp beads.

Then why do we talk about the full power of the lamp holder? Because at the beginning I said that the current of the solar LED lamp can be adjusted. We have all learned that the actual power = operating voltage * operating current, so even a 30W solar lamp is practical The light will not be 30W brightness.

　　 Now you know why the 50W LED head is not brighter than 30W. Of course, the quality of the product is also a key point. You can choose to take a look at Yangzhou Duliang Lighting Co., Ltd. The company's products have been sold all over the country, and the quality is universal. I believe that you can use it with peace of mind.
