Bear in mind that *each* point on a lighting circuit must be considered
to be 100W or actual load if greater, with no diversity. The assumption
is that all the lights could be on at the same time. Max load on a 5/6A
lighting circuit is about 1200W or 12 points, so unless your circuit is
already very lightly loaded you will probably be non-compliant with the
Regs.


I had always read that one as only applying to standard BC/ES fittings.
If the lights in question are LV then they'll be limited by the
transformer to n Watts and that's the figure I'd use. If they are
GU/GZ10 then the fitting usually has a (heat-related) limit, often 50W
(though I believe 75W GU10s are available?) so again, I'd use that
rather than 100W. Likewise R63 bulbs are very difficult to find above
60W, and the fitting may not be rated above that anyway.

Works for me anyway :-)

Hwyl!
