The circuit is based on IC1, which is a 555 timer IC in astable mode. It will power a 6 inch 4 Watt fluorescent tube off a 12 volt supply, consuming 300 mA. It may also be powered by a suitably rated universal AC/DC adapter. Advantages of the design are:....

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....

Here is the schematic diagram for a 20 Watt driver. I developed this circuit in 1985, and used it to build a lamp that found much use both as camping light and as emergency light during the then-frequent power outages.
The two transistors work as a....

This inverter is very easy to construct, reliable, and even powerful enough to light up a 15W florescent tube (if you cool your transistor well). The only hard-to-find piece of this baby is the so-called yellow inverter transformer. It's a miniature high....

The lamps are usually used as ballast or electronic ballast inverter. Here it is used to reduce voltage capacitor reactance. Interesting is also the method of ignition of the auxiliary electrodes involved over 150 Ohm resistors. To start simply involve only....

The circuit was designed to experiment with using small fluorescent lamps as a broad pattern source of modulated light. The circuit hits the small lamp with narrow 1us pulses at a rate of 10KHz. Each pulse launches about 10 watts of visible light. The lamp....

This circuit is basically a 8W inverter circuit. The circuit continues to be intended to drive an 8W fluorescent lamp from a 12V power supply, utilizing an cheap inverter primarily based on a ZTX652 transistor. The inverter will operate from supplies in the....

While they have been with us for many years, fluorescent lamps remain somewhat mysterious to most people. This isn`t really surprising, since their operation isn`t simple. The tube itself contains a mixture of gases, but the active ingredient is mercury.....

Compact Fluorescent Lamps [CFL] are low in price, plentiful and easy to find. Unfortunately, the current crop of these lamps seldom lasts as long as their warranty. Usually only the electronics fail and the lamp part of the bulb assembly are still very....

A fluorescent lamp has quite a few unique requirements to get it to start up and stay illuminated. How does this flyback converter manage to do these things I had first looked around to see if I could find a schematic for this fluorescent lamp assembly, but....

Whenever there is a need for battery-powered lighting, like for camping, solar powered cottages, cars, boats, planes, or emergency purposes, fluorescent lamps have a great appeal. Firstly, they are very much more efficient than glow lamps, so they produce....

A number of people have been unable to find the transformer needed for the Black Light project, so I looked around to see if I could find a fluorescent lamp driver that does not require any special components. I finally found one in Electronics Now. Here it....
