I have a one way dimmer switch 400w which controlled a plate with 4 x GU10 50w bulbs, each time a bulb goes out the dimmer blows, it will switch off and on but not dim, obviously this has blown, WHY does it do this everytime one bulb blows, i thought the 400w rating of the dimmer switch would be more than adequate for 4 x 50w bulbs?
Please help......
