Extractor fans not working with LED bulbs? Your electricity provider must have deliberately reduced the supply to prevent a total blackout, probably because of bad weather. Because LED lights can only take a fixed wattage of bulbs. I don't know why this resulted in lower voltage going through instead of arcing, but that's probably a good thing. This is in a slightly-difficult-to-get-to spot, hence the question instead of pulling out ladders and playing with different bulbs / configurations. The majority of these dimmers are TRIAC Dimmers which phase cuts the AC waveform at the start (leading edge) which reduces the amount of electrical current the bulb receives. Another could be that lights are not adjusting with the If this does not work without problems, sometimes the entire LED technology is demonized as not mature. So, lets get right into it!
