Having installed a commercial LED ballast and found that the ‘off’ setting leaves the LEDs glowing faintly, I have heard of a second case of this phenomenon.
The glorious editor (blessed be the ground he walks upon) stayed in a French hotel room that had LED bedside lights, which also continued to glow when ‘off’.
Added note: This blog seems to have been corrupted when it was moved (at this end) from one system to another. Some comments seem to have evaporated, resulting in lost wisdom. The general layman answer to the glow problem seems to be: if glowing occurs after replacing incandescent bulbs with led bulbs, buy a similar led replacement made by a well known reputable brand, and replace one of the glowing ones with that. If it doesn’t glow, maybe replace the rest. Led bulbs vary hugely in quality.
Now we are curious. Has anyone else had such an experience?
I have not fully investigated mine yet, but through some quick comparisons would say that my LEDs have around 100µA passing through them, and it may be 50Hz leakage.
Much as I realise there may be as many causes as instances, including me messing up the installation, but does any one know what is going on here?
Bleed through the primary to secondary EMC capacitor maybe? – but where would the return path be?
