Capacitor Ballast

william chan

Hey,

My calculations seem to suggest that the 18w coil ballast for a 240v short fluorescent lamp
can be directly replaced by a 1.2uF 600v film capacitor.
This would reduce heating inherent in coils.

Either should permit about 75mA through.

Anything wrong with my calculations?

The ballast also functions as a high impedance step-up transformer to get the initial arc established in the tube.

Good discussion of the topic at http://members.misty.com/don/f-lamp.html#fb1
