Circuits Designed by Dave Johnson, P.E. :

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 . . . [Circuit by Dave Johnson P.E.,  03/26/99]

 

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 . . . [Circuit by Dave Johnson P.E.,  06/27/00]

12 Volt DC Fluorescent Lamp Driver -  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. . . .  [Circuit designed by Aaron Cake]

 

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 Mornhinweg]

 

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. . .  [Collin Mitchell's web site]

 

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. Here it is. It uses a normal 120 to 6V stepdown transformer in reverse to step 12V to about 350V to drive a lamp without the need to warm the filaments. . . .  [Aaron Cake]

 

220V Non Dimming Ballast -  Efficient fluorescent lamps and magnetic ballasts have been the standard lighting fixture in commercial and industrial lighting for many years.
