These lights were taken down when I moved out of my first apartment.
White and black light, on wall.
Four lights on wall.

Three LEDs in a 60x35mm black plastic box, suitable for mounting on wall. Can be made with numerous color combination and intensities, build with internal resistor for 5V power supply.

The power LEDs are bought at: LED Shop


  • White
  • Warm white
  • Red
  • Blue
  • UV (black light)
The LEDs used for the lights on the picture has later been exchanged with 2xWhite 24.000 mcd and 1xRed 7000 mcd. --Thomas 15:50, 5 September 2008 (UTC)
