1 Watt Fluorescent Lamp Night Light - If you are tired of replacing small night
light lamps, try this circuit. The line powered circuit uses a long life cold cathode
fluorescent lamp. A simple charge pump technique runs the lamp without any
transformer. ….(designed by David A. Johnson) |
|
12 Volt DC Fluorescent Lamp Driver (Aaron Cake) - This fluorescent lamp driver
uses a normal 120 to 6V step-down transformer in reverse to step12V to about350-Volt
to drive a lamp without need to warm filaments. (added 04/03/02) |

12v Fluorescent Inverter - 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....(project added 04/09) |

12VDC Fluorescent Lamp Driver - 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....(electronic design added 6/07) |

20ma LED Ballast - I use this circuit for general use to power white LEDs, like a
headset light I use on my desk and a keyboard light for my computer. I built it into a
tiny Radio Shack project box (270-288), which y no longer sell. I put heat-shrink
tubing around female output connector (RS P/N 273-1743), ....Designed by Andrew

3-Way Dimming CFL Ballast - 3 way dimming system widely adopted in US with
conventional filament lamps consists of a light bulb that has a modified Edison screw
type base which allows 3 connections to be made to a special lamp socket that also has
3 connections. (added 3/05) |

42 Watt Compact Fluorescent Ballast - CFL-2 is an electronic ballast design for
driving a 42 watt compact fluorescent lamp from a 120 or 230 volt AC line.
circuit was designed using IR2156 Ballast Driver IC. main features of
circuit are programmable frequency, preheat time, over-current threshold and dead
time. (added 3/05) |
|
5W Fluorescent Lamp Intensity Modulator - 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 starting method is a bit crude but
the circuit does work. ….(designed by David A. Johnson) |

A Ballast that can Be Dimmed from a Domestic Phase Cut Dimmer. - A system has now
been developed, based around IR2156, where ballast is able to operate with
minimal flicker over a considerable portion of adjustment range of a dimmer and
light output may be controlled over this range from maximum output down to around 10%.
