I fitted an IP44 light in my bathroom. Included with the light were two
strips of wide, thin black "insulation sleeving". These are supposed to

anybody explain? They don't seem to serve any purpose because the wires
are naturally alreay insulated anyway with black/red insulation, and if
the sleeving is to prevent water from getting to the terminal where the
Live and Neutral wires connect, this would still be possible even with
All those I've met before have been in sealed fittings where heat build
