These lights were taken down when I moved out of my first apartment.
LED light 2

A single four chip white LED in a small plastic box, used as a dot light.


In my old apartment I used these small dot lights under shelves above my desk. If mounted close to the wall they give a cool cone effect, not terribly bright but pretty decorative and not intrusive. And they are really easy to make; one LED, resistor and a small plastic box, 10 minutes, tops. Powered by: 5V.

They also fit nicely at the top of a window frame, shining light down on the window post. Here is an image example using a 5mm LED.


  • White
  • Warn white
  • Red
  • Blue
  • UV (black light)
