Re: Lighting Design for Kitchen

["Paul Bendall" <paul@xxxxxxxxxxxxxxxxx>]

Just a couple of thoughts from my own experience with lighting in the
kitchen.

I use LED 'strip' lights for under cabinet lighting with a cold white
temperature. These are very good indeed coming on instantly with no
hum and drawing very little power or heat. I sourced a LED driver
from Canada to reduce the number of drivers I would need. I think it
is something like 40W as opposed to 10W - 20W of most LED drivers.

I also have blue LEDs as uplighters on top of the cabinets aimed on
to the ceiling to create a splash of colour. Again this works very
well and is an ideal use of relatively low priced and low power LEDs.

In fact most of the time the cominbination of these two light sources
is more than enough for most tasks in the kitchen. In total the over
cabinet and under cabinet LEDs use ~60W which is considerably less
than halogen's and I believe creates a nice effect.

One gotcha with the blue LEDs is that I ended up with two orders from
different batches of lights and the blue colour is slightly
different. Not a mjor issue for me as I have one cabinet isolated
from the rest so they went here and are unnoticed. But worth
considering when ordering coloured LEDs
