[color=rgb(51, 51, 51)]The use of a red LED is a popular choice. I don't trust just a resistor[/color][color=rgb(51, 51, 51)][/size]and an led strip lighting in series across an AC line voltage of 120. I suggestthat you use an adaptor with an output of 12 Volts AC. This willextend the life of the led strip lighting outdoor with the use of a 470 ohm 1/2 wattresistor in series. Why the adaptor? This is used to keep powersurges from destroying the LED, which I have seen happen.If a surge happens, the voltage spike will be lost in the adapter'stransformer. Why 12 volts AC output? this is used because anLED only conducts electron flow in one direction. This means thatthe 12v led light bars will flash at the rate of your line voltage, which is 60 cyclesper second here, in the States. In Europe, it is 50 cycles. 60 is justfast enough so that the eye doesn't see the flash rate. 50 you cansee a flicker, but you can get used to it, after a while. This is assimple as I can explain it to you. It will be dependable, too. Feelfree to e-me. I will be happy to give you more information and helpif you need it. :lol
