Experts talk about how big is the working current of led lamp?

Just for lighting, 1mA can be used for display purposes, generally 5- 10mA; for low-power LED lighting white light, the working current is 20mA, and the high-power 1W current is 350mA；;

The working voltage varies with different colors, white light is generally 3V, and red, green and yellow are generally 1.8V to 2 V. 。

The rated working current of indicator LED is 5MA.

The rated current of low-power LED is 20MA.

The rated current of 0.5W LED is 150MA.

The rated current of 1W LED is 350MA.

The rated current of 3W LED is 700MA.

There are many sizes of LED chips, and the light efficiency is also very different. In addition, the process and materials used are very different, and the use environment and heat dissipation treatment of LED will affect the actual working current setting value of LED.
