MICRO LEDS contd


Following on from my last post I can tell you that each LED is wired, as you would expect, in series. I was unable to tell by looking at the LED which of the wires was the positive one so I had to do a little experimenting with low voltage DC to work that out. That done, and because I have a terrible memory, I then applied red nail varnish to the first 20 or so wires so that I wouldn't have to perform the test again. ( To assist my memory I used red nail varnish - kindly supplied by SWMBO on the positive wire).

This is one LED connected to a 5volt supply.


A few things I like about these LEDS - the wire is stiff which makes for easy manipulation and handling. The LED itself is also covered in a thin plastic making it more robust than some prewired  micro LEDS that come with very fine and flimsy wire.  There is a downside in that the wiring is harder to hide but for station and house lighting that should not be a problem. In fact so far I have found the stiff wire can be used to position the light and hold it in place - say on the ceiling of a waiting room,  whilst a drop of PVA is applied and allowed to dry.
