From what you have written, its pointing to one common component as all lights exhibit the problem at the same time. I'm going to make the following assumptions: -The LED lamps are for the transformers supplied. -No other lights are on the dimmer switch except the ones in question. -No other lights in the house are showing the same problem at the same time or at all. What I would do is the following: 1) Get the electrician to bypass the dimmer. See if the problem shows without the dimmer in circuit. I know that you are keen on the dimming capability but by physically bypassing the dimmer we can rule that item out. See how it goes for a week like this. 2) If the problem is still present, get your electrician to check the active and neutral connections from the circuit breaker to the first light. Reason for this is a loose connection may be just making contact. Loose neutrals in installations play havoc due to voltage drop. 3) If the above doesn't work and it is now pointing to the dimmer, you may have the wrong dimmer mechanism. There are two types-leading edge and trailing edge. Ensure you have the correct one for the LED lights. Your electrician should be able to nut this out. Best of luck, let us know how it goes. Re: Led lights flickering (once an hour or so) - why? dimmer 10Sep 19, 2013 9:58 pm Alright, so I have not had this fixed yet, but I have some updates. We have two sets of led lights on dimmers. Both sets has the same symptoms. Our bedrooms has ceiling fans (one with a dimmer, the rest without) and they are all experiencing humming (no flickering). The flickering and humming happens at the same time. I also started timing it, and it is happening on regular intervals, so it is something on a timer causing it. For example, I wrote down some times when the lights flickered one night (and I was doing other things, so it probably happened every 30min and I just missed it) 7.01 pm 9.01 pm 10.01 pm 10.31 pm 11.01 pm 11.31 pm As you can see, it is extremely consistent. I've googled this problem and got a few results, but not sure what to think exactly. Seems to be a lot of talk about ripple control, could that be the issue? Not a hundred percent clear on what that is or whether it would be this regular. When this happens, the lights will usually blink once quickly, and then maybe a couple of more times shortly after. The humming from fans however is constant and lasts maybe 30sec or so at a guess. None of the lights in fans or elsewhere around the house is flickering (they are all CFL). I assume the problem is probably happening everywhere, and other lights are not as sensitive? That sucks! Hope it all works out. Good to move away from steel anyway for all your reasons, but it's also thermally poor. 16 17888 Hi All, I just wanted to close this topic out with an update.
