@Saandeep Sreerambatla • 07 Dec, 2010 IF you are talking about the Old tube lights, there is a difference in the operating principle.

What you generally observe is,

when you switch on your tube light, it flickers for few seconds to minutes to start. But in case of CFL you dont see this!

The principle used in tube lights is Electro Magnetic ballast. In CFL it is Electric ballast.
@rohit bisht • 07 Dec, 2010 ok. what abt comparison of their architecture??
