Help 170 leds in series parallel Answered

5 leds in series, way too many resistors can I use constant current? If so how many strings of 5 could be connected with 12 to 14.7 volt supply?


Thanks have been testing with a constant current driver with some good success. Gets just a bit warm, going to put a heat sink on it at final assembly. I will inform more if any problems arise

doubt it, i did the underglow LED mod, and had the same issue... you have to have a 5 or 6 series of leds... thats only 34 or so resister. id tell ya to tough it out and get your soldering gun heated up. but i agree with lemonie check the link

Thank You I am using that calculator want to eliminate the large number of resistors, hopefully by using constant current
