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.

Circuit diagram

Parts:

C1 100uf 25V Electrolytic Capacitor

C2,C3 0.01uf 25V Ceramic Disc Capacitor

C4 0.01uf 1KV Ceramic Disc Capacitor

R1 1K 1/4W Resistor

R2 2.7K 1/4W Resistor

Q1 IRF510 MOSFET

U1 TLC555 Timer IC

T1 6V 300mA Transformer

LAMP 4W Fluorescent Lamp

MISC Board, Wire, Heatsink For Q1

Notes:

1. Q1 must be installed on a heat sink.

2. A 240V to 10V transformer will work better then the one in the parts list. The problem is that they are hard to find.

3. This circuit can give a nasty but not too dangerous shock. Be careful around the output leads.
