1 Watt Fluorescent Lamp Night Light - If you are tired of
replacing small night light lamps, try this circuit…. [Designed by David
A. Johnson] |
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….

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) |

12 Volt fluorescent lamp drivers - Three schematics of 12 V
drivers for 2, 8 and 20 Watt, plus a lot of explanations about fluorescent
tubes. Use the drivers for camping, emergency, boating, etc. [Manfred

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)......(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 R. Morris (added 6/06) |

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) |

40 Watt Fluorescent Lamp Inverter (Aaron Cake) - This40W fluorescent lamp
inverter allows you to run40W fluorescent tubes from any12V source capable of
delivering3A. (added 8/03) |

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%. (added 3/05) |
