These are flexible LED strips from the 3M company, a roll of 300 leds costs around £7 on Amazon.
The roll is easily subdivided into units of three leds which are in series, with a dropper resistor for use on 12 volts. The strips are self adhesive on the back. Individual led chips are about one eighth of an inch square and could be unsoldered from the flexible backing and incorporated directly into say yard lights or lamp posts with a suitable dropper resistor
As supplied, the white leds are very bright and very white, I've made the colour more 'gaslight' by sticking small disks of some old yellow OHP film I had knocking about, over the business end of the chip. - never throw anything away...
To reduce the brightness, I've wired two strips in series. Each strip fits along the opposite side of an internal dividing wall, and reflects off the inside of the buildings roof. Hopefully, when all is finished, the leds will impart a nice homely yellow glow.
Photographs to follow.
