- Have you changed your lights to the new energy efficient led light bulbs and now they flicker when they dim? Or does the dimmer switch make a loud buzzing noise?
Well this video can help you!
It explains the importance of compatibility between the light bulbs and the light switch and demonstrates how to achieve flicker-free dimming.
It also gives some troubleshooting tips if you’re still having problems and finally, it looks at the latest trend in dimming - dim to warm lights.

Thank you very much, I had a similar
Problem with a incandescent dimmer trying to use these LED's. The folks in the hardware store had no idea what I was talking about.
you answered all my questions about Dimming. bet you have excellent advice for life in general
Just wanted to say Thank You! I have learned so much from your videos. 😊
Thanks for the feedback 😃
Fantastic explanation which will make my handyman job next week significantly easier - thank you
Brilliant! Good luck!
very clearly explained thank you
Great stuff all the questions you wanted to ask but never did
Very clear explanation, now I know why my LED light bulbs are flickering.
It was conventional florescent bulbs previously.
Brilliant, thanks for the feedback! I’m glad the video was helpful.
Excellent video thank you so much💪💪
great video!
Great to know. Lady. Thank you
Very helpful video. I didn't know I needed to look at range on the dimmer switch or that dim-to-warm was a thing, because I have been really disappointed with my dimmed LEDs. They just make the room grey, so I haven't moved from incandescent in TV room yet, though I would love to.
Great content! I learned a lot :)
Working at hardware store. Trainee. No nothing 😭 thankyou for helping me.
Beautiful video.
Thank you!
Thanks !
Thanks for all the amazing videos. Learned a lot!
I have a 10 light chandeliear and wanting to upgrade it to dimmable filament light. i have a smart dimmable switch and was told by the switch manufacturer to get bulb that's 5w and above to prevent flickering. however i only found either 4w or 40w choices for filament bulbs. if i go for the 40w bulb will it be overloading 40 x 10 = 400w? dont really understanding how to walt works within the same circuit.
need some advise here.....thanks!
Hello, i love your desk lamp!, please, which brand is it...?.thank you, best regards
Thanks! It’s from made.com in the UK
HI Eleanor quick Q pls. Can you mix one dimmer with many toggle switches to control one line of lights (eg a long corridor with 12 lights and 4 switches but only 1 dimmer in the middle needed)
Fantastic I think you just solved our ‘disco’ problem. What are your views on ‘smart switches’ as hoping to solve the bunk bed light switch off problem?
If the room is being renovated I would put in a normal 2 way switch by the door and within also reach of the bunk beds. Personally I prefer actual wiring over wireless where possible.
For a retrofit solution, wireless smart switches are a great low cost solution with minimal upheaval as no new wiring is required.
If you like the techy side of it - go for it! They are fun, you can get colour changing bulbs etc. Look at ranges like Philips Hue.
Hey Eleanor, I was wondering if you can give some insight as to the problem we have here. We have recently had new led Spot lights added to our new ceiling, our original dimmer switch is still on the wall but just like this video the new LEDs don't dim with our dimmer on the wall (they blink & cut off). I want to know can we sort this problem with just getting new dimmable LEDs or do we need to replace our dimmer/switch on the wall? Also how can I find out if the LEDs in the ceiling our dimmable?
I would appreciate your input on this as we had asked the electrician to make the new lights dimmable which he didn't. Thanks alot,
The bulb in the ceiling is "LXGU10LED/4.5W"
Hi Ciaran
Thanks for you question. It should say on the light bulbs if they are dimmable, so if they don’t state that I would assume they are non-dimmable. An internet search of that part code comes up with the Luxna GU10 bulbs. The 5W version is dimmable, the 4.5W (which you have) is non-dimmable. You will also need to ask the electrician to check that the dimmer switch is an led compatible dimmer switch otherwise you will still get problems with the dimming.
Trying to find combinations that work is still an issue. I've got a light fitting that takes 5 LED bulbs. Have tried many different makes of bulb and dimmer over 4 years. When dimmed I still get an annoying flicker at the mains frequency (50Hz). As far as I can tell there is no way to fix this. What I thinks needed is a dimmer that does frequency doubling or uses a higher PWM frequency.
Dimmers and efficient lamps must make low and medium frequency radio reception inside the home impossible, especially an apartment with reinforced walls. One could simply run an extra wire and switch on half of the lamps and use any brands. A year or two later you won't find the same design model.
This just goes to show how utterly complicated everything is getting! I never ever thought I'd need to call an electrician to change a lightbulb, but I can see it happening.
Eleanor, I have a table lamp which I bought from ikea. I have tried so many dimmable lightbulbs and none are compatible (apparently) with the switch.
I was about to either throw the lamp out, or remove the inline dimmer switch and replace it with a simple on/off inline switch.
You video was great but not quite solved my problem. Any advice to offer? :0)
That is annoying! You can buy led inline dimmer switches, I have never used one but it might be worth a try. Check the minimum load rating as it may not dim down far enough. Otherwise your options are as you said - to change it for an on/off switch (with a less bright bulb) or get a new table lamp. Good luck!
What type of bulb does your table lamp support? If mini fluorecent, forget it. They can't be dimmed.
For a TRIAC Power Supply what kind of dimmer switch do I need?
The Varilight V-Com series are suitable for TRIAC (leading edge) dimming

@@eleanorbell Thanks!
Dimming and flickering problem is more complex. Channging only dimmer or changing only bulbs to dimmable LED is not enough.
i have flickering with a LED compatible dimmer switch - but the miniload is 60W. I'm guessing this is too high for the three modern LED bulbs
Yes, a dimmer with a minimum load of 60W will be too high for just 3 led bulbs (unless they are at least 20W each). Your best option is probably to change the dimmer switch. If you’re in the UK check out the Varilight V-Pro range - their dimmers have a minimum load of 0W.
Just a suggestion, tell your watchers to turn off the power before doing any work!!!!!! MAINS KILL'S

She does not explain what a LED dimmer is. (trailing edge etc) Maybe she does not know.
THAT IS AN INSULTING INSINUATION. PERHAPS IT'S TOO ESOTERIC FOR THE
INTENDED ATTENDEE TO THIS VERY WELL WIRED (YEAH, PUN INTENDED) COURSE.
LOL. We're supposed to take advice from a woman???
