May I ask what low-voltage has to do with energy savings???
Like others have noted, you run 110v into the transformer, 12v is fed to the lights which are every bit as bright as can be. I used them over my sink (recessed) and under cabinets (line strips) when we did the kitchen over last year. I'm assuming that even though the feed is 110v, the amp draw is less than running regular incancesdents. Running fluorescents means that they're usually a slow warm up to full brightness especially here in New England where it can get a bit cool during the winters. I'd like to run these on a motion sensor but of course have the option to leave'em on when I want to.
The fluorescents are a decent back up plan, and I'd like to have the sensor located in a different location from the lights. The reason I asked about exterior was because there are so many low voltage landscape lights out there, I thought maybe there might be some company with cans.
