Schematics of delabs - Tubelight Electronic Choke

Tubelight Electronic Choke

This is an electronic choke for a Conventional Fluorescent Lamp. This was an application note of MJE13005 a High Voltage Switching NPN Power Transistor. I Might have modified it. This was very popular in the early days, The Coil Winding and Ferrite is very Critical design.

The diodes, npn transistor and caps are high voltage 350V-1KV, The tubelight is 40W-60W 5 feet long. This circuit replaced the choke and starter in an existing frame.
