Following the bathroom lighting saga and lounge lighting saga (to be
resolved next week - hopefully...), last night my bedside light would
not come on.
It's one of two lights, each with an inline dimmer, and with a common
power lead to a single 13 amp plug. Many possibilities to go wrong, but
it was just the switch contact in the old brass bayonet socket which had
worn out. So off to the darkest corner of the garage to find the old
spares box, and a similar switched brass socket. But that was also
dodgy, with a similar problem. No more old brass sockets in the box, but
a switched plastic bayonet fitting was fine. I replaced the lights in
the bedroom, plugged them in, and they were both ok.
That was early afternoon, so with the good weather I went out into the
garden to get some tidying up done. I came back in to find the power was
off in the lounge. A quick check of the the split CU showed one of the
RCDs had tripped. Nothing else showed as faulty, but that RCD was one
which was in the circuit for the socket for the repaired bedside light.
Aaargh! But jumping to conclusions can lead you astray, so I switched
off all the MCBs on the side of that RCD, and switched them on in turn.
It wasn't the bedside lamp tripping the RCD! But it was the house
lighting - that which I'd had so many problems with recently.
But that's jumping to conclusions again. To cut another long story
short, it was one of the 5ft fluorescent lights in the garage. I'd
needed to turn them on to have a look in the spares box. For some
reason, one of the three separate fittings was tripping the RCD as soon
as it was turned on. I haven't had a chance to have a look, but I'd
guess a possibility is the choke or maybe the insulation on one of the
live wires has failed.
I'd guess the fittings are over 20 years old; we've been here well over
6 years and none of the fluorescent tubes has been replaced. I'm toying
with replacing all the fittings as they are so old. I suppose I should
be thinking of leds (with batten), but a high-frequency fitting and
triphosphor tube isn't as expensive as a led/batten and is almost as
efficient as a led (leds - 24W/3000lumen; fluorescents 58W/5000lumen).
Neither will get much use, maybe a couple of hundred hours a year.
Anyone changed to leds, or stayed with fluorescents?
