New downlights - flickering

[mazdaq]

Yesterday, I installed a new 300W electronic dimmer which controlled 6 low voltage downlights. All was fine. Today, I've changed the downlights to 6 new 50W mains voltage downlights.

However, one of the bulbs is now flickering. I've tried changing the bulb but doesn't make a difference. Could the problem be the 300W load is at the maximum for the dimmer?

Thanks.

If only one is flickering it can't be the switch.

If only one is flickering, and you have just installed the lights, my money is on a loose connection.

Let's be clear with this please.

Are you saying you simply replaced a lighting system running at 12v by changing the bulbs to 230v / 50w

or are you saying you took out the transformers, wired the fittings for direct mains and then updated the bulbs ?


A dimmer hates being used at max ouput, so yes the 300w dimmer should be replaced with a 400w one.

As for the fault, since I'm not sure what you actually have done, I won't comment.

I took out the transformers and wired the new fitting onto the the direct mains and put new 50W GU10s in.

Will try a 400W dimmer. Thanks.

[shrug]If the dimmer is acting up then it would be affecting all 6 lights.[/shrug]

It is prudent up the dimmer rating, but that won't clear the immediate problem, as Ban All Shed's mentioned:=

Hope that clears it up- check the wiring, look for cable cores that have slipped to the side of the terminals and haven't made good contact. Turn the juice off 1st and do a visual and tug at every termination.

You may find that the longevity of your dimmer will be compromised, especially if you used gu10's as you are supposed to consider the derating, unless the dimmers are iQ.


But go and check the connections to that fitting

It was a loose connection. Thanks very much for the help.
