If it is light up it looks like a fairy is buzzing around the bulb :-)

It´s an old 200Watt stained bulb where I removed the inner parts.
I replaced the inner parts by 10 RGB LEDs with automatic colour changing.
Yo can mount such a bulb on a stand like picture one or put it into a nice box like on licture two.

Have fun and lets see how to build it.

Step 1: The Parts...

An old bulb (never again throw bulbs away) ;-)
Colour changing LEDs
Some small aluminium tubes (used for the end of flexible wires)
Some copper fittings an tubes
A switch
A battery holder
Some wires
Some glue
Two component clay
Shrinking hose

Step 2: Preparing the Bulb

Use the aluminium tubes to crimp the LEDs together. Like on picture 1 and 2.
Picture 1 shows 2 LEDs crimped together. You can use solder as well. But crimping is a bit easier. ;-)

Use shrinking hose to insulate it and solder wires at the end.
All LEDs are parallel connected and they need 3V without any resistor!

If you are finished, just make a test, attach 3V: CLICK

Use two component clay to fix it inside the bulb.

If you attach power it looks like this: CLICK

Step 3: Put It Into a Case or Build a Stand

You can put it into a nice case and hide the cables and batteries under need the velvet or you can build a wooden stand with some copper tubes and fittings.

To do so you have to prepare a base plate.I used "Multiplex".
I drilled a hole for a switch and on hole for a copper tube (22mm).
I used wax stain to stain and polish the wood.
Than I soldered the tubes and fittings together, polished them.
The long tube will be the battery case.

Step 4:

I glued the bulb into a fitting and attached the polished copper holder inside the 22mm hole.
With some hot glue I insulated the battery holder and it fits exactly inside the copper tube.
The cabling is very easy. Just from the battery holder to the switch and then to the bulb.

The switch it on....
