I would like to make some PVC candles for my graveyard using the tea light candles but need help with powering them. I set my display up the first of October and it is up until the first week of November. The batteries that come with the tea lights would never last and the hack with 4AA batteries wouldn't work for me either. I have all of my tombstones lit with LED spotlights from MiniSpotlight.com and they are powered with their power supply, which outputs 12 Volts. I run low voltage wiring between each row of tombstones with a LED Spot shining on each stone. All of the LEDS go to the one power supply mentioned above. I have about 30 Spots and would like to be able to use the PVC Candles in front of the tombstones and just connect to the wiring I am already using. Is there an easy way to add a resistor somewhere to drop from the 12v to 5v so I can still use my existing set up? If so how do I figure out what resistor to use? I remember reading someones post that the tea lights can handle 4.5 - 5 Volts only before blowing the circuit board and LED. I know just enough about wiring to be dangerous so I am looking for the simplest way of doing this, I don't want to have to make a flicker circuit or run additional wiring through my graveyard. Any help will be greatly appreciated.
