There are two boxes downstairs, one of LED bulbs with burned out power supplies or burned out serial elements, the other with 12VAC power supplies.
Please help yourself, I will take both boxes home with me before the working bee at the end of the month. I hope to finish the job that Alistair started of removing the functional LEDs from these units.
To clarify: these are 240V LED packages. Some have downconverters to power a small number of LEDs (three or four, you can see them in the picture). Others have a long series string of LEDs of which one has burned out (those are the ones with a heap of LEDs on the surface, one of which is black).
The 12V power supplies are for “low voltage” halogen (or “dichroic”) downlights. The two boxes of stuff are incompatible.
