We have a candelabra which, until recently, had eight 40W incandescent lamps fitted. These have gradually been replaced by 4W, 32mA LEDs, (the filament type), with no appreciable reduction of light levels. However, the last two lamps failed this week and were replaced with LEDs and the whole fitting now flickers. This fitting has three switches, (much to the amusement of our Dutch electrician), which operate through a 'Soft Start/Soft Finish' gismo somewhere in the system. The LEDs are not 'Dimmable'. I suspect the flicker is due to the fact that the 'gismo' is now handling 32W instead of 320W, but it could be the dimmable/non-dimmable conflict.
Any advice will be welcome, especially if you know the proper French name of the 'Gismo'.

It amazes me that when you buy lamps that work for ever ( says so on the plastic package) that they fail within 6 months !
Gizmo( note the spellink) in French means gadget

Remove the dimmer and use a simple switch and the LED lights will not flicker.

When you bought the lights (led) are they dimmable (your spelling)? When I bought replacements for our fixtures, the sales person asked the question and gave me the correct ones.
Your "gismo" could be malfunctioning. Is it easily checked, replaced? Maybe the "gismo" is not needed as they are led now.
Arthur should be around to give you the facts, maybe in dutch though..

what's wrong with Dutch then ? A touch of American racistism ?  |

Nothing wrong with the Dutch, as far as I know: our electrician, now retired, is fluent in English, French, Dutch and swears in German!

The Gismo is needed to allow switching from 3 locations, according to our Electrician. Are the LEDs you bought the filament type? What's wrong with 'dimmable'? |

@ Biggles: traditional light bulb dimmers need a minimum load. Mixing bulbs, halogen or LEDs can produce flickering. To complicate things even further: finding the right combination of a special LED dimmer and a specific type of LED - many technologies, many different producers - is not always easy.....sometimes something of a black art. Soft starters? Yes, for heavy electrical motors in industry. In your case probably a more or less clever dimmer.
French names: variateur de lumière, variateur LED.

Sorry.. My "spell check" says it is wrong and gives dilemma and mandible as options... 
Need to change that...

It was a replacement for an old type halogen. A 7cm strip that usually comes in a standing fixture with a dimmer knob. Gets very hot..
This one is wall mounted reflective fixture with just a switch (on/off) on the wall.

Thank you for that Robert, I need to do some research - or bribe my electrician to take a day out of retirement! |

If you have, as already stated, a much lower standard than the minimum load required to properly operate your dimmer/gizmo, then it may be that a Compensateur is required. They are easy to install/attach and are reasonably low priced, in the region of 7 - 8€.
