A relatively simple method is to distinguish LEDs by their light color, which is the color of LED beads. You can also use the following methods to determine the specifications or voltage in volts. Below, please refer to the editor's explanation! 1. Direct insertion is a low-power specification that includes: straw hat/helmet, round head, concave, oval, square, flat head, round head/bread type, piranha, etc. There are colors such as white, green, blue, yellow, and purple. The power of white, green, blue, and purple colored lamp beads is usually 0.06 watts, with a current of 20 milliamperes and a voltage of 2.8-3.4 volts. Red light, orange light, yellow light, and pure green light range from 1.8 to 2.4 volts. 2. High power LED bead atmosphere imitation lumen 1 watt. There are several specifications for 3 watts and 5 watts. The high-power LED beads have colors such as white, red, green, blue, yellow, and purple for 1 watt. The power of white, green, blue, and purple colored light beads is usually 1 watt, with a current of 350 milliamperes and a voltage of 2.9-3.6. The power of red, orange, yellow, and plain green light is 1.8-2.4 volts. The above is about how to determine the voltage of LED beads. We also provide direct insertion and high-power.
