I installed some LED strips in the clothes closest, appliance cupboard, both drawers and the electric service cupboard.

I purchased 3 rolls of warm white LED strips from China on-line for 15 bucks for 5 metres (~16 feet). You can cut the strip every 3" and solder power wires to the power pads on the strips.
I was hoping to use concealed magnetic switches as used by security systems. Trouble is they are NO (Normally Open) when the drawer or door is open. For this application I need NC (Normally closed) and those versions are about 10 times the cost. I tried using a second magnet, but the tolerance to get it working were very close. I settled on some small lever micro-switches. They are working OK but the switching tolerance is only about 1/8". I may end up throwing a microprocessor at it to invert the switching. Then I can put a time-out timer on the light as well.
I found the strips in the electric service cupboard fell off after 30 minutes or so. The double-sided tape, while labled 3M, is not great. The little bit of heat from the strip eventually turned the glue to goo. I epoxied those two strips today, we will see how that holds. The other strips are holding, but the use is intermittent in those applications.
I took a pic of the drawer without a flash to show the light from the strip. The second pic I used a flash so you can see the drawers I was photographing.
