Why do my light bulbs keep
blowing?
If you are having problems with your light
bulbs blowing then this doesn’t mean
that there is a big wiring fault. This is
a problem that’s been around for many
years. If it was a wiring problem then it
would have been spotted by the fuses and
MCB’s before it has half a chance
to get to the light bulb its self.
There are many reasons why a bulb would
blow. One of the main reasons is usually
that if you purchase cheap bulbs then the
quality is not good and the smallest surge
of power can break them. It’s a good
idea to spend that extra few pence to get
a higher quality, longer lasting bulb and
it will save you money long term.
If you have a loose connection between the
bulb and the fitting this can also cause
the bulb to blow. The reason for this is
that the circuit will not be complete. Be
sure that the bulb is tightly in position
to avoid this.

When your bulb blows, most of the time
(99% of the time in fact) the fuse/MCB for
the lighting will blow/trip as well. This
may make the problem appear bigger than
it actually is.
