John, To use a term you used to embarrass another forum member..."What planet are you from"? It is clear you skip read. First this was Tom's subject not Shawn's. Shawn jumped in and the conversation was all over. At the point Shawn asked a question about LED it didn't seem specific to TMCC, in fact he used the term "standard engine" what ever that is. Ron gave an answer about AC engines not mattering, and I refined Ron's answer to address standard LED, and screw in LED in an AC application or a TMCC half sine wave application.
So again nothing I stated was wrong, but you have to jump in with an insult or sarcasm. It seems you make assumptions to make your point of view the only correct one.
These become historical post others can learn from, so it doesn't hurt if there is a little more detail in the answer. G
Tom's problem was also TMCC, so your comment still is totally off topic. Just admit you were wrong and move on.
