PL questions

[Simon]

jus found out my 4ft PL burnt out.. so went to get 1 pair of tube and change, only to find out, one of the tubes not working.. interchange and still the same.. is it possible that my fixture actually have 2 ballast instead of one? or the ballast that i have just partly faulty?

thanks

Why dun you check if physically got 2 anot? Else Either Connection problems or time to change your ballast...

[Simon]

gerald, will remove the case and check

is the light set the one on your 4' tank?
they are JKS right. 2x36W PL for each set.
it has got 2 separate iron core ballast,
one on each side of the light set.

mok, my not jks.. but some unbranded taiwanese lights.. but it has 2 recess on each side.. supposely for a ballast.. guess I have to unscrew and check

thanks
