Dimmer LED Flickering

[Les84]

I was wondering if anyone can shed some light (excuse the pun) on an issue I am having with dimmer LED Bayonet bulbs.

I have a twin dimmer switch down stairs, one controls lounge lights and other does landing. When I switch on the upstairs light using the switch downstairs after a while the light starts flickering on and off, any ideas as I have it with two of the same bulbs now. Upstairs switch is a standard rocker switxh of that makes a difference.

TIA

Are the LEDs dimmable products?

Are the dimmers LED specific dimmers.

If yes to the above, maybe fit a standard switch instead of the dimmer, could be the lamps are breaking down or the dimmer is broken down.

Thanks for your reply.

The LEDs are dimmable compatible, as for the dimmer switch it’s been over 10yrs old so I very much doubt it’s led specific.

I had this problem. It was limited to one particular make of bulbs. Swapped them for another make and the problem went away.

I am using Homebase own brand TCP or what ever it was.

I had similar and had to change to an led dimmer switch

I had a similar issue. Replaced with these type of switch, problem solved:

You may need to program the switch, however in my case that was not needed.

I had the reverse problem last week - my (non-Led) downlighters were flickering after I installed a new dimmer switch. Never occurred to me that dimmers could be LED 'specific'.

Cue lots of reading about trailing edge and leading edge dimmers - checked the dimmer - yes, LED specific, so I changed the bulbs to LED and problem solved.

In short, make sure the switch matches the bulbs

I will try different bulbs tonight I think, the two downstairs in the lounge that run off the same 2 gang switch don’t do it.

How would they need programming, thought a switch was a switch lol.

Also I see some have a max load etc. 3 bulbs at 4w each should be ok with this one?

Mating LEDs and dimmers seems to be about as easy as mating Pandas.
I had a quick look into the technicalities a few years ago and there was leading edge and trailing edge types which liked different types of bulbs …

I eventually adopted the swap things until they work approach.

Haha didn’t think a simple task had to be looked into to in-depth either.

I'm old school and was quite surprised too. Thankfully son is a sparky and sorted it all out. Here are the instructions to program the switch I quoted:

In my experience, even "LED-compatible" switches may not play well with the bulbs. I took the same route as another poster, swap out the switch until it works.

This was in Canada where the wiring and voltages are different so YMMV. I found a slider with "off" at the bottom of the slide range and "full" at the top was pretty flaky. Replaced it with an LED compatible switch that had separate on/off switch and slider did the trick.

Had similar problems until I switched all my dimming bulbs to Philips dimmable ones.
