Discuss Bulbs flutter with dimmer in the DIY Electrical Advice area at ElectriciansForums.net
With incandescent bulbs, this sounds like a loose connection, a failing dimmer, or a dimmer suffering from overload.I have 3 pendant light fixtures with a total of 540 watts of incandescent bulbs connected to a GE electronic dimmer. The bulbs flutter from bright to dim randomly. I have seen this with LEDs before but not incandescent bulbs. What is wrong?
I did wonder given this is for 120V, whether dimers in the USA typically had a higher current rating than UK.most dimmers for filament lamps are 400watts max. I've fitted a few 1kW dimmers wherever the load has been > 400w.
One thing I would try would be to take the dimmer out of circuit (eg turn power off and connect the permanent live and switched live together at the switch), turn power back on and see if the flickering continues.Thanks for the responses. The switch is rated 600W incandescent at 120v.
Good idea. I will give it a try.One thing I would try would be to take the dimmer out of circuit (eg turn power off and connect the permanent live and switched live together at the switch), turn power back on and see if the flickering continues.
If it does there is something up with the wiring.
Time to call an electrician, or if you are competent with electrics, go round checking all the connections on the circuit, eg tightening screw terminals and checking wire nuts.
