- 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.

- 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.

- 60 Watt Lamp
with Auxiliary 14v LED Lamp
This circuit controls power to a standard 60 watt lamp plus generates an
auxiliary 14v DC supply which can power an automotive style 12 LED array.

Incandescent Lamp Inrush Current Limiter
This circuit limits the large inrush current often associated with large
incandescent lamps. With the components shown the current is limited
to 1 amp, but it could be scaled to any desired current. (added 7/06)
