Yes..i do agree with your words. We need to put our experiences and skill to make some things work better as per our requirements. Thanks for the valuable info.

The problem I´ve found is that in this circuit the current assumes a sinusoidal form, with a high peaking value. Using very cheap leds this caused 3 of them to fail in 1 month. Using rectification and filtering the current is almost constant and now the circuit has been working fine for almost 2 years.
