Top 5 Positive Customer Reviews for 30 w cob
!! Attention !!! For the 4 pinsleds (3W) one pin has a "-" on it, this is a Do Not Connect pin !!! Not the ground The VCC is the big metal pad UNDER the LED, and the 3 other pins are the R, G and B grounds. This is why, I think, other buyers say the led don't works .... They works ! :-)
