Introduction: Convert Lamp From Kerosene to Flaming LEDs

About: Be limited only by your imagination.

Several years back I made the Martha Stewart Witch and Cats Halloween yard figures. You can download the pattern and instructions here Martha Stewart Patterns and see the Instructable I wrote about it here Instructable Link to Witch Project

This Halloween I decided to convert the oil lamp to LEDs that mimic flame. I did this primarily because it was more convenient than refilling the kerosene lantern daily. The LEDs were from Amazon and are quite inexpensive. LEDs from Amazon . They work out to about ten cents per unit. They draw very little power and the four AA batteries powering the unit should be enough to energize them the entire month of October. Still, I had a switch in my spare parts box and it fit perfectly into the kerosene filling hole so I put it in and I can turn the device on and off whenever I want to.

Step 1: Parts and Tools

  • Tools
    • Dremel with cutting disk and sanding disk
    • Eye protection
    • Soldering Gun
    • Heat Gun to shrink tubing
    • Bandsaw to cut plexiglass
    • Compass to mark a circle
    • Drill with 1/16 bit to make pilot holes for the plexiglass and countersink bit.
    • Driver for screws
    • Wire strippers and cutters

Step 2: Preparing the Lantern

  1. Remove and dispose of any kerosene properly
  2. Thoroughly dry the old kerosene chamber
  3. Put on eye protection
  4. Using the dremel with the cutting disk cut the bottom of the lamp leaving about 1/8 inch for later attachment of the plexiglass. Be careful because the edges will be sharp at this point. Remove the cut out piece and recycle it.
  5. Using the sanding disk, smooth the sharp edges.
  6. Remove the wick and using a driver clean out any old material so that the LED's can easily pass through.
  7. Measure the opening of the lantern and using a compass, scribe a circle that diameter minus 1/64 inch.
  8. Using the bandsaw, cut the circle out.
  9. Using the 1/64 inch bit drill four pilot holes thru the plexiglass. Do this one at a time and put the screw in each time so that the plexiglass doesn't shift.
  10. Remove the plexiglass and clean out any plexiglass or metal drilling residue.

Step 3: Wiring Up the LEDs

  1. Electricity flows from the negative pole to the positive pole of a battery. That is from the bottom to the top pointy end. So you want the electricity to go to the resister on the negative lead of the LED.
  2. Crimp (bend and squeeze) the negative leads of the LED's and attach a resistor to each. Solder them. Put a piece of shrink tubing over this and use a heat gun to shrink it.
  3. Crimp and solder positive leads and shrink tube it.
  4. Feed the LEDs thru the old wick port. Let them stand about 1/2 inch up so that you can see them when you assemble the unit.
  5. Insert and fasten the switch into the kerosene port. You might need a washer.
  6. Wire the two battery holders in series (one negative lead gets soldered to a positive lead). You can of course use a 4 battery holder. In fact you can use just two batteries and skip the resister altogether or you can get away with using a button cell battery and just tape the led to the leads. So many choices!
  7. Attach the negative (usually black) lead to the switch).
  8. Attach the other end of the switch to the negative LED lead (the one with the resistors).
  9. Attach the positive leads together and put a wire nut on it.
  10. Insert the batteries and check function.
  11. Refasten the plexiglass bottom.

That's it! I hope that you enjoy this Instructable and I would be delighted to hear your comments, answer your questions and see your versions!
