Finally installed the snubber yesterday. All working beautifully. Many thanks to all who assisted :D

Could someone please tell me how to size a snubber for this arrangment. We have now tried a 5W 10ohm ceramic resistor. When placed in parallell with one of the LEDs I still get the dim glow. I expect that there is a solution here as the 60W incandescent worked and I guess that the ceramic...

Thanks again all. Adam_151, the standard switching cable is 2 core 1mm² wires insulated in red and black respectively with both insulated with a white sheath. I did try using standard power cable for the switching wire (running 1,2 to 1,2 in the diagram) and in Australia this has an...

Can anyone guess why a shorter wire might work? I'm not sure its induced current as the intensity is the same irrespective of if the long switchwire is coiled or spread out. I even tried one with a decoupled switchwire (ie two separate wires). If it was induction, can I purchase a 240V...

Thank you all. Tim, the incandescent lamp works but it is not appropriate to use in the final arrangement. (see also reply Posted: Sat Aug 25, 2007 6:40 pm) Breezer, Your suggestion is essentially what we have done in study i - albeit with only one led. Our next study will be...

I have some new developments. The supplier of the lights was good enough to offer some technical advice and three replacement fittings, which I will call 4,5 and 6. They initially suspected the capacitors for holding charge. This was studied by waiting for them to dim - they don't even...

I have now placed the last in place of the first. Both with and without the last two lights connected. The problem persists, although interestingly in the case of all lights connected the problem does follow the first light fitting. I can sumarise all of the test configurations as...

:oops: Sorry. url should work now. Thanks for the edit tip.

Thank you all. A picture is available at http://web.aanet.com.au/dragonfly/Transfer/led%20housing.jpg I am guessing that the brown thing is the rectifier. The low wattage bulb is an ingenious suggestion although we have selected LEDs for the stair as they use little power and we may elect...

Thanks Breezer, I could do the swap but I am assuming from my first test where I took out the first one entirely and the others glowed that they are all the same and that the problem is with the circuit and not the lights. I think the lights are AC as there is no visible transformer...

Thanks for your swift reply Tickly T. I feel much relieved now. I tried an incandescent and, as you speculated, it did not glow in the off position. I then decoupled the two core switch cable by adding an temporary cable and ensured that the two were spaced well apart. I recall from high...

We have just installed a series of lights illuminating an internal stair. The lights are small rectangular banks of LEDs (connected in parallell) operated by a two way switch (one switch at the top of the stair, one at the bottom). The lights work wonderfully however one of the lights (the one...
