Re: Lighting Design for Kitchen

I have been looking at the Light Corporation for a while. They are=20=20
based just down the road from me.

I was also looking at Jonh Cullen but as you say they are expensive=20=20
and also design to use their own fittings, this pushes the cost up.

The only thing I can't currently work out is the required illuminance

320 lux	Recommended office lighting (Australia)[8]
400 lux	Sunrise or sunset on a clear day. Well-lit office area.
500 lux	Lighting level for an office according to the European law
UNI=20=20
EN 12464

If I go with 500lux I end up with 25 lights just in the ceiling


Drop that down to 320lux and it comes out at 16 fittings.
