Dimmer keeps blowing

[liamruairi]

Any advice is much appreciated. I have a new light fitted, 10 x E27 40watt filament bulbs. Its this one: 10 Lights - Edison Chandelier Pendant Lamp Ceiling Light Bulbs Remote Control | eBay

I have now fitted 5 dimmer switches and not found one that works. Leading edge dimmers buzz really loud and trailing edge ones keep blowing. I bought a 400w varilight remote dimmer which worked lovely, then i turned it on once (full brighness) and it blew. I thought i needed an over-capacity dimmer so bought the same but 600w version (max light fixture watt is 400 - 10x 40w bulbs) and same thing happpened. Worked dimmed for few hours, turned off, then on again at full brightness and it blew. What am i doing wrong? Do i need an even bigger capacity like a 1000w dimmer?


thanks for advice!

1. Try a 1Kw dimmer a 400w is not big enough

2. How deep is the back box - if its 16mm or 25mm trying adding a "forward" spacer.

3. Fit an on/off switch

or

4. Change the light fitting

I had similar problems on a chandelier once , in the end I used a 1000W in line dimmer above the ceiling that had plenty of ventilation and replaced the switch with retractive one , never had a problem after that ..

the cold resistance of the lamps is a lot lower than when hot. use a rotary dimmer (as opposed to push) so that it's not possible to turn on full whack. lamps will last a lot longer as well. should manage with a 600w or 700w then.

yes you're quite far out at nether edge, the closest Yess electrical is penistone road hillsborough, edmundson electrical at catley road attercliffe or electric center near Sheffield arena, but I would say out of the 3 yess electrical have a better range of decorative switches and lights on display in store.
