RE: Lighting Design for Kitchen

[Paul Gale <groups2@xxxxxxxxxxxxxxxx>]

John Cullen OEM a number of fittings in their range - if you search
enough,=
you can sometimes find the original manufacturer at better prices :) I did=
this for a fairly pricey high wire system (although it still cost around a=
grand!)

Re lux levels - I think you're thinking way too bright - best way is to
loo=
k at other peoples kitchens and compare (plus photos etc of other
designers=
schemes). I would have thought somewhere around 12 x 50W downlights in tha=
t area would be more than enough - depending on what other task and effect
=
lighting you have?

Paul.
