New low energy lights fitted recently, lower power demand etc., good.
But my daughter discovered that even when switched off they emit light.
Spooky to have glowing lights on the bedroom wall at 3 am. Anyone know
the cause and a solution other than reverting to tungsten filament
bulbs?

it's been covered hundreds of times before in this and other groups. It is
caused by cheap nasty starter circuits in Philips light bulbs. The tube is
triggered by tiny currents between neutral and earth which is why it happens
when the switch is off.
Philips told me this and changed the bulbs I bought for ones that don't do
it. They were the 18w variety.
It is not a fault with the wiring or anything else, it is the bulbs that
should have had a safety recall as they are dangerous in my opinion.
Try a different make, don't bother with Philips as faulty bulbs are still
being sold.
