LED Dimming unbalanced, bulbs flicker and pulse

[Bristolian]

Evening guys!

I have three of these bulbs on a ceiling light, controlled by a dimmer switch installed by an electrician:

Unfortunately there are a number of issues:

- For 8/10’ths of the range of the dimmer from low to high, the lights are all on but extremely dimly.

- Around 8/10ths, the bulbs very briefly, very slightly dim even further.

- 9/10ths to 10/10ths of the throw, the bulbs rapidly light through what I assume is their full range of brightness.

- At all levels of brightness, the bulbs flicker and pulse very obviously, making them hard to comfortably eat dinner underneath.

I appreciate this could be the bulbs, switch, both or something else so I’d really appreciate any help you can provide as to how to diagnose/resolve!

If useful to provide the switch I have, I’ll take it out and find the part number.

Thanks in advance for any help you can provide!

Those lamps have a built in dimming mechanism, they are not designed to be driven by a dimmer.

If you read the product description it states quite clearly that the brightness is selected by repeated operation of the switch.

On that basis, it's possible the action of altering the mains waveform (done by the dimmer switch to control the brightness) is triggering the internal dimmer.

Either change the lamps to dimmable ones and check the dimmer switch you have is designed to drive dimmable LED lamps (I personally recommend the Varilight vPro dimmer modules) or change the dimmer switch to a simple on/off switch and rely on the internal dimmer to provide three different light levels.

Turns out I’m the dim one!!

Thank you so much, I’ve taken your advice and replaced the bulbs, and everything works perfectly.

Thanks again!

You're welcome.

To be fair... I've never seen a lamp with an internal dimmer, so I would probably have been wondering what was going on if I'd been in your shoes

I have this problem with some non-dimmable LED GU10s in my kitchen (switched from a non-dimming switch) which pulse annoyingly (and varyingly, for no apparent reason).

When they are switched on or switched off?

When switched on - when the are off they are all 'dark' as intended!

It is very common to hear of LED lamps flashing and pulsing when they are switched off.

Wow - they are just riddled with problems, aren't they! I've never experienced it, so perhaps I should count myself lucky. Thanks.
