I was looking to fit it in an area where dark colours are, such as the
worktop of the dark wood surround on the base of the cupboard units.

I may go with the idea that Rodney Hall has give me in another email
of using some ally strip from B&Q etc.
One thing I was maybe going to do is to use a PCB for all the LED
fitting. By making a standard size PCB of say 15mm x 300mm, I could
make them linkable and allow more to be connected together. A recent
idea was to put a CAN bus controller on each one so that I would
have independent control of each module etc, with only a simple 4
wire interconnect.

My cabinets are fitted slightly away from the wall. The top bar is
fixed to the wall, but by drilling down through this, I can drop
cables down the back. This is what I did for the touch screen
computer I have fitted already.

I have been checking around looking for something much more powerful.
The Luxeon ones look great but the price is very high. I may buy one
or two to give them a try though.

I like the idea of some in the cupboards with a hidden magnetic switch
to detect when the door is opened and switch the LED's on. mmmm
