Royal Ediswan 100CP Pointolite Lamp - Circuit

Here is the circuit we used to light our 100CP Pointolite lamp, design courtesy of Andy (Photonicinduction). It consists of a 65W fluorescent choke feeding a full wave bridge rectifier to run the lamp, the ignition is achieved by the simple use of a 6V battery (a 4Ah SLA battery is recommended), which just needs to be applied for 4 or 5 seconds, then when it is removed the arc should strike. Do not leave the battery connected, use a momentary switch.

Note - this circuit is for a 240V 50Hz supply, you may need to experiment to find the correct value of ballast for 120V 60Hz mains.

Photon is a brilliant engineer. Cool

Very similar principle for running a Deuterium lamp. Once the arc strikes so long as the current is sufficient the cathode doesn't need external heating.
