I'm wanting to illuminate the area around my kitchen sink. There's a cupboard over it and when you stand at the sink the room light is behind you. I thought about getting a self-contained strip light that just plugs into the mains rather than wiring something into the lighting circuit(s). Screwfix sell them. I can screw the light to the underside of the cupboard. I'm a bit worried about the metal sink and all that water being a few feet from the light. There's no earthing - sink to pipe, pipe to pipe. There is an RCD though.
Is there anything about an energy saving bulb that might make it more likely for a fuse (5 amp) to blow in a table lamp?
Finally, I'm thinking of adding a second light to an existing light and switch, plus moving the existing light. I can't find instructions to do this anywhere on the web. Plenty of info on adding a new light /and switch/. I don't fully understand how it all works - I was a bit surprised to find that the mains and the switch both go to the light. I thought a switch came between the mains and the light - hence "switch". Must confess I'm not too sure what the neutral wire does either. I know, I know - if I don't know want I'm doing I should leave well alone but if the instructions are clear I should be fine :) The light's in the cellar and is on it's own fuse. All the cables are in sight.
TIA
