Does anyone know what the regulations are regarding the fitting of
miniature/small lights under cabinets which are above - or near - the
sink area? Presumably, the low voltage (say LED and halogen) one are OK,
but do they need to be driven by a 'proper' isolation transformer,
rather than some not-really-isolating switchmode gizmo?

And what about those running directly off the mains (say low wattage
halogens and fluorescent)? What can be used which conforms to the latest
regulations?
