In 2011 I bought a basic Maplin 'decorative' LED strip lighting kit (A07JT) for the kitchen at the 'offer' price of ~£25, but only 'temporarily' fixed it up, actually sticky-taped (as very lightweight) under a cupboard above a work surface but we had not used it much as the quantity of light was maybe not quite what was hoped for.
(One attraction of this system was that the LED strips run at 12V, 12.1V measured at the unloaded mains adaptor in fact, so they could plausibly be driven from my off-grid 12V system if required. The strips are nominally ~0.53W each though the adaptor is rated max 1A ie 12W.)
The kit includes a mains adaptor, three LED (cool white) strips, various connectors and fixings, allowing the strips to be assembled many ways. Nicely done.
The extension kit of three more LED strips and more connectors and fixings (A08JT) that plugs into the existing strips and mains adaptor, came on offer again in Jan 2012 (~£15) so I bought one and fixed up the system properly to banish the worktop shadows between cooker and sink. The clips and screws are easy to use (the sticky pads were beyond me), and I'd put up the enlarged system in somewhere over half an hour.
As of 2012-07-01 we're not using this lighting very much.
2012-09-07 measured 'on' consumption as just over 8W and off as undetectably low (nominally <0.1W) so can be left plugged in for convenience without being a 'vampire'.
