How do you calculate the current of the LED light belt?
The current band can be cut at any length, so most of them are 12V power supply in parallel.
Non lighting each group current is about 10~20mA., each 3 lamps are a group. Lighting type about 50mA a group (different manufacturers, the current is also different), then you see how many lights, divided by 3 to get the number of groups, the number of groups of single current can get the total current
