LED bulbs flashing on table lamps

[yartin]

Hi

I bought 2 different brands new table lamps, 2 new sets of E14 LED bulbs (OSRAM 6.5W and ARGOS 3.4W). All bulbs are dimmable and table lamps have 3 stage dim functions.

On all set ups and on both table lamps, the bulbs goes fom off, low, high and flashing and back to off when table lamps toiuch dim functions used. All bulbs works perfectly on rotary dimmer switch.

Why flashing?

Thanks

To work some electronic switches, not only dimming switches, a very small current is passed through the bulb even when off to work the electronics, if the by-pass resistor in the bulbs is not large enough, then the bulbs will flash.

Way to stop it is a capacitor across the bulb contacts or different bulbs, or a dimmer/switch which uses the neutral, or has a battery in it, or simply use smart bulbs and remove the dimmer.

The dimmer is built in the table lamps, 3 step touch dimmer.

BTW the two lamps are of different manufacturers so are the bulbs.

Whatever dimmer is built into the table lamp is not compatible with LEDs.

With the price of a smart bulb today, who wants a dimmer built into a lamp, I can understand when using 8 bulbs, so dimmer switch works out cheaper, but a standard lamp or desk lamp, there is really no point.

Money is no object.
Two bed side table touch lamps are easier and more convient to operate and is preferable in this application.

I also have a touch control table lamp in my bedroom, never touched, as it messes it up, I will assume set to max, with a smart bulb set to minium output, which is 10% where a dimmer switch only goes to 50%, and I simply say hey google turn on/off desk lamp, but I am only one in the room, so voice does not matter.

Likely a tungsten bulb will work, and if mine, that's what I would do, for the amount of time the lamp is on, cost or heat unlikely to be a problem, just use a tungsten bulb.

Underrstood. The touch bedside lights that you have are not compatible with the new LED lamps.
The solution is obvious.
You could:
1. Ask the manufacturer/supplier to tell you the correct replacement LED lamp,
OR
2. As Money is no object, buy new bedside lights.

I have already bought 2 sets as said in my first post, are you saying to buy a third set? It's a bit silly suggestion,no?
I can live with off, low, high, flash. TBH the flash is a good feature for a bedroom table lamp.

I have contacted both suppliers, one said they will arrange collection...

You can still get tungsten bulbs they are more expensive to getting a smart bulb, but that's the easy way out.

I know I still have a draw full of them, should really put them in the bin. Do you live anywhere near me? Can't really post them.

Ahh. So you bought the lights and the lamps separately?
Maybe I misunderstood. If you bought them separately, buy a product that is delivered, complete and working.
