The on going problem
of repairing
underwater lights
will be with us for
ever.
You must first hope
that the builder has
left enough cable
wound up behing the
lamp to allow it to
be removed to the
side of the pool for
repair.
Most lights have a
lamp capsule which
unclip from the wall
after undoing one or
two screws & can be
lifted to the deck.
If you can't do this
then you will have
to empty the pool
down to below light
level.
Once you have the
light clear, & have
made sure the power
is OFF, remove the
seal retaining
screws & remove the
globe or lamp. You
will be best to take
this with you to the
pool shop to
identify the
replacement. You
will normally need
to replace the
gasket at the same
time as the globe or
lamp.
