A client has something similar to rope lighting running in a shallow groove on top of her kitchen cabinets. It's controlled by a SP switch above the counter top. The voltage at the switch is 115 AC but there is 12 VAC to the lights. A lamp cord comes out of a hole in the wall and splices to the "fixture". The lamps themselves are spaced 2" OC and they are in a rigid, clear plastic housing. Two questions: Does anyone know where I can get something similar i.e. 12V strip lights? Could I step-up the voltage with a transformer mounted on top of the cabinets and use 115V rope lights? I can find those. Additionally - I can't find the step-down transformer for the existing lights. It may be inaccessible. Thanks, Don
Be careful! Make sure the transformer is a listed class II transformer - I know a lot of the WAC jobs do not carry a listing for "field installations". (You can tell by the reverse R and U together - this indicates that UL recognizes this product but it is to be used as a component of another product). If the wiring behind the walls is zip cord and connected to these lights the transformer has to be a LISTED class II to protect against fire and shock hazard. I have also seen the lighting you have indicated in the 120 volt varity - if it is, your customer may have a problem, and also a hazard. You can check the listing number at www.ul.com to see what the product is listed for.
I can't believe the transformer would be left inaccessible in the walls. This house is only around 10 yrs. old. It's a very large home costing probably 500K to 1M new and the electrical materials are what you would find in tract homes complete with back-wired spec-grade receptacles. I'm changing every one that I get near. Lots of dead outlets due to it's upstream neighbor with loose connections.
>>I have also seen the lighting you have indicated in the 120 volt varity - if it is, your customer may have a problem, and also a hazard. It's 12 volt, why would it be a hazard if it were 120 volt?

donles, WAC is a lighting manufacturer. (try WAClighting.com) Article 411 prohibits lamp cords from being run through or concealed behind walls. The price of the home doesn't necessarily reflect the level of workmanship, particularly if it is in a development.
