How to calculate.the current of led strip?
Examples are adopt SMD5050 encapsulation,A total of 60 pcs led,3pcs led divide into pairs,Each Group contains a resistance. Input voltage as 12V, powe is 12W. Do you know how much current Each LED has ?
Let’s break the question down:

1、60 PCS led module, 3pcs led divide into pairs,which means Tell us about the A total of 20 groups.

2、Input voltage is 12V, 3pcs led divide into pairs, Each Group contains a resistance. The means is total of 20 groups to parallel connection

3、Total power as 12W,That’s the single strand of led strip’power just has 0.6W

4、Because the led strip was parallel connection , so That’s the single strand of led strip’voltage as 12V.

5、We finally arrived at the conclusion that. Single led module current = 0.6W÷ 12V = 50mA
