HI All

Another weird thing.... g
I 'won' a couple of double fluorescent fittings - probably 2ft tubes -
a pair of them.

They seem to share a common ballast - but each tube has its own
separate starter.

Sounds odd to me but might be normal, smaller fixtures tend to be very
'individual'.


When switched on, only one tube strikes.
With the other one I can see the heaters on - but it won't strike.
If, after the first tube has struck I remove the starter from the
'dead' tube, it will then light - but won't light from cold.

Swapping the starters makes the fault move from tube to tube.
Swapping a starter from a working 4ft single unit into the fault
starter position doesn't improve the situation.
The 'faulty' starter works fine on the 4ft single unit.

I'm confused !

Are there different types of starters - or is there likely to be a
fault on the twin ballast ?

There are different types of starters yes, but if it's within the
wattage rating, it should be ok.


Any suggestions (apart from 'go buy a new unit !)

Check the earthing. (Shouldn't be critical to the operation on a
switchstart fitting but you never know).

Kick it? (J/K)

Thanks
