I happen to have an RGB LED lamp comprised of 199 LEDs (66 red, 67 blue, and 66 green) and I dropped it, destroying an LED. I want to repair it with an LED from newark, but I just don't know what to purchase. The LED is in the middle of a series of LEDs, and the total voltage is 18v, and it seems like the voltage drop is about 1.6v per LED, up until the broken one. I am not sure what to pick out in terms of foward voltage and current, etc. Can anybody help? Below is a diagram I put together.
Thanks for your help!
