1. Have you put pennies in the meter?
2. Was the fitting working yesterday?
If so when you last switched it on did it flicker for 30 seconds
the lamp black at each end? If very black change starter and
if lamp ends are not black, change starter switch.
Note: Starters for 70w / 75w / 100w are different from "universal
8watt to 65 watt starters. Twin circuit 18w / 20w will need
a quality starter.
OK so it still does not work.
Well hi kick may help but causes hernia so .................
change lamp and starter for ones that are working in another
It is possible for a choke ( the box like object inside the
fail but normally it is because the lamp has been left in
a failed condition
whilst trying to start the lamp the control gear has overheated.
If it has been left in overheated condition it will have to
be replaced by another with a three year warranty from TLC!
What if the fitting is an old 1800mm/ 6 feet long 75/70 watt
2400mm)? Then the lamp may not work because the fitting had
circuit with a choke in series with a 440volt capacitor. If
starter switch problems these capacitors can fail after 8
years and will
have to be replaced by the same value item.
What if it is a twin and only one side is out? Then if it
is a 75 watt the
leading circuit capacitor is the problem.
OK so it is a brand new fitting
straight out of the box and has never been used
1. Ensure starter is twisted in.
2. Check volts are present at the term block.
3. With electricity off (ideally at mains) check all
wires are in all connections.
4. Using neon screwdriver check fitting is live on
both connections of choke.
5. If a twin or multi tube fitting there may be a crossed
connection,or only one tube works
to check for this ensure that wiring is followed through and
that the circuit for each
lamp is intact,
terminal block to choke -
choke to tube -
tube to starter switch -
starter switch to other end of tube -
tube to negative on terminal block
( each tube has two connection at each end )
with twin 18/20watt the end of one connection in each filament
in adjacent tubes are joined together.
6. Check that the supply in the building is not less
than 235 volts.
OK so it is much more modern and has electronic high frequency
and it has worked for say two years, personally I would give
up and look
for replacement control gear. If it has never worked and you
have NOT megga
tested the fitting then complain!
Suppose it is a new installation and one fitting in ten is
properly, have you over loaded the circuit beyond the rating
of the switch
or beyond the supply current?
