Hi

I was wondering if there are any guidelines as to how close together
these need to be for a kitchen where we will have an approx. 4m run of
work top in an L shape with no wall cupboards.

I am considering the mains voltage 50W type, and want a bright working
area.

Oh dear.
I suggest you read back through earlier threads on halogen
downlighters before going that route ;-)
