Problem chandelier?

[rocker]

Anyone got any ideas about this? I've got a chandelier which has 8 bulbs. Apparently, every month or so, the customer has to replace all the bulbs, and they are all blowing at the same time. It's probably blindingly simple but I can't het my head around it....

You would not want to wire them in series would you,

had one recently where a gu10 spot blowing, took out 1 bulb of every other fitting in the circuit... and tripped the mcb. Never recurred and never found a fault as such. But i put it down to a very brief, but high, inrush type current when the bulb went pop.. which took out the "weak" bulbs elsewhere along the circuit.
Perhaps when one of your bulbs on the chandalier is going, something similar is happening. A very brief, but high current rushes through the fitting and takes out all the others..?
Would definitely check the quality of the bulbs being bought and perhaps go for lower wattage..

GT1 I was thinking that - maybe the filament is causing a small short which is somehow having an effect on the rest of the bulbs..... it appears the MCB trips 'sometimes' when it happens, so this could be the problem. As someone siggested I think I may just load them up with completely different bulbs, maybe LEDs or energy bulbs.

Might be worth just buying the best quality bulbs you can find and giving that a bash.
They obviously wanting a lot of light out the thing so decent branded bulbs from perhaps osram or the like, may present a solution.

Had it a few times now, where client buys a light fitting. Bulbs start to blow, so they buy even cheaper bulbs, which last even less time, so they go out and buy the absolute cheapest things you can get, sometimes off eBay !!

When in reality if they had gone the other way, and bought more expensive, better quality bulbs, that vicious circle may have been broken.

That's assuming it's the bulbs of course !!
