Step 1: Materials and Equipment
LED tea light "candle"
3/4" PVC pipe (which has a diameter of a bit more than 1 in)
Silicone or latex caulk
White spray paint
Monofilament fishing line (darker color is less visible)
Hacksaw (to cut PVC pipe)
Hot glue gun
Note on LED candle lights: There are many different models of LED candle tea lights, and they can be obtained for very little cost (<$1 ea) from dollar stores, craft stores, even Costco. These lights are meant to replace candle tea lights and have a special LED which contains the flicker circuitry. (Note: Apparently, there is a second type of LED tea light which contains the flicker circuitry on a circuit board and not internal to the LED itself. You can probably figure out how to modify these instructions to utilize this type of tea light, but as I've never seen one of these, I'll tailor this Instructable to using the LED with the imbedded flicker circuit.)
Step 2: Disassemble and Modify the Tea Light
The housing of the tea light consists of the plastic "flame" which holds the LED, and the body of the candle itself. The diameter of the candle is slightly larger than the diameter of the PVC pipe. Using a sharp utility knife, Dremel-type tool, or saw (I carefully used a band saw.) trim the sides of the candle away and reduce the diameter of the candle top to match that of the PVC pipe.
Step 3: Build Candlesticks
Solder extension wires to the LED leads so that they extend several inches longer than the PVC pipe. A small dab of hot glue to attach the LED into the "flame" will prevent pull-out. Next, hot glue the trimmed tea light top to the PVC pipe, making sure that the wires extend through the pipe to the other end. You should now have something that looks like a crude candlestick. Touch the two wires to opposite faces of the 2032 battery to check that the LED still works. If no light is seen, reverse the leads. LEDs are polarized and must be biased properly. If the LED starts flickering, great. If not, check your steps to make sure that your solder joints are sound, and that a wire didn't break.
Step 4: Getting Creative
To power the candle, position the two wires on opposite faces of the battery, and wrap the assembly in a fold of paper. Clamp with a binder clip to keep the wires in place. I've found that a medium size binder clip will just fit into the bottom of the PVC pipe if the ears of the clip are folded closed again. A single battery will last many hours.
