I purchased the following LED product from Radio shack
http://www.radioshack.com/product/index.jsp?productId=2062568
I bought 4 of these LEDs and had to return 3 of them after a few hours of testing a circuit.
I have a power supply that is 12V and 1A. The LED is supposed to have a resistor built in and someone in the comments noted that is was a 680ohm resistor (??). I thought that should be OK.
I also dropped the voltage down to 9V and still experienced an outage with one of the LEDs.
I'm tried of going back and forth to Radio Shack Am I doing something wrong in the wiring? Should I throw another resistor in for good measure??
Thanks.
