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?
