CCFL lamp tester

[HellasTechn]

Hi there friends,

I am thinking to buy a ccfl lamp tester, specifically this one :

I have a question though, how can i tell which side of the ccfl is anode and which is cathode ? does not polarrity matter ?
Can i just connect it either way ?

P.S. I am also open to suggestions for ccfl testers.

THANKS !

From my understanding, polarity doesn't matter with ccfls. It has no filament nor anode /cathode, it works on AC.

All the fluorescent light tubes and compact bulbs on Canada have a filament at each end.

That's true but that's not a ccfl.
A ccfl is a cold-cathode fluorescent lamp like whats used for backlighting a laptop computer display.

And CCFL's are driven by AC, so no need to distinguish one end from the other.
