There are two kinds of LED linear projection lamps: DC and ac. except for Japan's AC110V, domestic general internal power supply is connected with 220V power. We usually judge the external power supply as low-voltage DC24V and DC12V. According to the needs of customers and according to different lamp manufacturers, the voltage is also different. So what is the voltage standard for LED floodlights?
We need to pay attention to a problem when choosing the power supply of the floodlight and find the corresponding voltage. The voltage of general LED linear projection lamp is generally divided into 220V, 110V, 24V and 12V. But like many 18V, 36V voltage projection lamp products, many people think it is not normal, in fact, it is not so.
It is not easy to find 18V and 36V transformers on the market. For transformer manufacturers, this is a non-standard and infrequently used product, with less consumption and large relative resistance in the production process. Therefore, the common low-voltage products on the market are generally color 24V or 12V. This depends on having become the default and common standard value within the row. But 18V and 36V are also produced, but they are not suitable for general use.
Therefore, when purchasing led floodlights, we should pay attention to the selection according to the industry's general standards.
