This is a low-cost project for 20 or 40 watt fluorescent tubes. However the most efficient is to use a 40 watt tube (or two 20 watt tubes in series). It’s a circuit you can put together from junk box components or build from a kit. It’s very simple to build and requires no printed circuit board.
The transformer is hand-wound on a ferrite rod (from an old transistor radio) and the winding wire can be salvaged from an old transformer.
