Flickering lights and 'bulbs' blowing

[alchemist]

Hi Guys,

Age old problem from a customer of lights flickering sometimes and 'bulbs' blowing frequently.

I'm thinking the usual, cheap lamps, loose connection, dodgy fitting(s), high voltage on supply or supply quality problems .

Can you think of anything else worth checking?

Thanks

Mike

switch contacts?

You have to apply some psychology sometimes.

I was called to investigate bulbs blowing. I really could not find anything wrong and suspected cheap bulbs.

In the past I've just told the customer it must be cheap bulbs, but this time I tried a placebo effect and told the white lie that I found a couple of loose connections and tightened them.

We will see if I get called back again.

I had a similar one this morning, good customer's aged mother. Been there before, replaced he various supermarket lamps with decent one, didn't expect to here any more as all looked good.

Still "blowing bulbs" went this morning and changed a switched, told her it had been causing a spike when she switched it on.

Hope that doesn't come back to haunt me!

also, are they ES or BC? found many ES where centre contact has lost its 'spring'. put some spring back into it (pull it forwards with long nose pliers), and that usually solves it

and then there are MR16 holders which fail all the time. more the lamp about (i.e change it) and it works

have you confirmed if the lamp is actually blown or not?. as above, disturbing contact (i.e fitting new lamp) and make a (temporarily) better contact, so new lamp works, then 'fails' after a short time
