Discrete Lighting C2P

The inspiration for this was the desire to have a dimmed light over the toilet.
When you need to visit in the middle of the night, you don't necessarily want to be "in the spotlight". For those who sit it's probably not so much of a problem, those standing need some light to aim.
This is a one-watt LED installed in the ceiling through a 25mm (1") hole. It is powered from a USB plug inserted into a USB/ AC adapter. The USB/ AC unit would be plugged into a ceiling socket as are other LED lighting.
There is a little bit of fine soldering required.
As the USB supply is 5 volts, a dropping resistor brings this into the 3 - 3.4 volt range required for the 1W LED.
The length of the heat sink strip is only approximate, the LED will reach about 60 deg. C without it. The aluminium strips can also help in installation (more later)

One 1W LED - SMD bead I have used "Warm White" but that's up to you.
