My builder/electrician is saying that Part P of building regs says that one halogen (he didn;t mention wattage) is required per square metre of room. This means in our 7.5m by 3.5m living room we would need 26 halogen spotlights which is crazy.
Anyone have experience of the building regs and.or recommended number of lights for a particular size room?
Judging by my old house where i had 6 x 50watt low voltage halogen spots in a 4.5 x 3.5 m room and that was more than sufficient, i think
1 spot per 2.5 to 3sq metres is more sensible.
