A fluorescent light starter in series with an incandescent light bulb makes a cool flickering light effect - useful for making a cheap strobe, Halloween haunted house effect, or simulate flakey wiring.


You can adjust the flicker to be infrequent or extreme depending on the watt rating of the light-bulb and the kind of fluorescent light starter. This is what I've found:

Starter Type90 Watt90 Watt90 Watt
FS-5 for 4-6-8 Watt.25 Hz.8 Hz1.3 Hz
FS-2 for 14-15-20 Watt6 Hz7 Hz9 Hz
FS-12 for 32 Watt0 Hz0 Hz0 Hz
FS-25 for 25 Watt4.5 Hz6 Hz5 Hz


When the light flickers, it momentarily turns off the light while a bulb (?) inside of the starter arcs. I don't know much about fluorescent lights, but by taking apart the starter it looks like it is simply made of a capacitor in parallel with the arc bulb. The capacitor may spike the voltage on the circuit, so I wouldn't use this on the same circuit as any fragile equipment. It seems like the bulb might burn out quickly, but I have run lights with the same starter for over a week straight and had no problems. I have, however, been able to break the starter by connecting it to too many lights (4-5 100 Watt Bulbs).

This is a cool Idea, I like the Random pattern that this gives, sorta like one of my old strobes with the nearly burnt out resistor, the complete random nature make for a much scarier effect.

Your table above does not look quite right or am I missing something. The load does not change. I know you created this post a while ago. Would you still have the data?
