Hi,
I replaced a broken ceiling light fixture with a new one from Ikea.
The fixture is on a dimmer switch.
At max power it is fine, when I slide the dimmer down, the fixture does not dim, instead it starts flashing.
Does this suggest that the fixture is not compatible with a dimmer, or is it not wired correctly? The manual says nothing about dimmers. If a fixture is not compatible with a dimmer, is there some component I can add to make it compatible?

Thanks

it says Light bulbs sold separately. IKEA recommends LED bulb GU10
400 lumen (3 pcs).

You likely put in non dimmable LED bulbs. Replace with dimmable GU10
LED bulbs and it will work just fine!!!!
