There are many China ebay sellers of LED strips that come on a reel. The
LED are spaced every inch or so apart and are driven off 12VDC. Dropping
resistors are on the tape. Current consumption is around 1A per 3'. So you
can make up series or parallel combos if you have a long run.
Cost is around $1 USD per foot or so. Some versions are covered with a
sealant to make them water tight and all the ones I have bought have had
self-adhesive on the back side. Installation on my basement cabinets was a
snap.
These can be driven with analog wall transformers to be RFI silent. And you
have a brightness adjustment (if you want it) by varying the voltage.
Very cool stuff.

Subject: Re: [RFI] LED Under Cabinet Kitchen Lights YES or NO
I think you can assume that anything that uses active circuitry to
convert the line voltage down to the level required by the LED lights
has the potential to cause RFI. You might look into whether any of the
LED manufacturers offer a linear (transformer) power supply option, as
some halogen manufacturers used to.

I have a big project coming up here, re-doing the kitchen. Currently using
some halogen light under cabinet lights right now. They do get warm/hot
but they are bright. A lot of the LED stuff I see in IKEA, Home
Desperate, and Lowes does not appear to be near as bright. But the bigger
worry is bringing in something into the house with the potential to
provide RFI grief. I did some reading on line where one guy indicated
that the power supply (he assumed) to his under cabinet lights was
destroying his AM radio. That's the last thing we need. Has anyone
suffered any ill effects like this from LED kitchen lighting? - Mike
