ES candle bulbs blowing

[parker56]

Hi guys & gals,anybody come across es bulbs blowing big time,I mean the glass parting from the screw base and flying across the room.
thought it might be cheap bulbs,but according to granny they have come from different suppliers.
going there later to have a look.
cheers

cheap lamps IMO. other cause could be surges/voltage spikes. you could try a 0.1mfd,600V capacitor across L and N of the lighting circuit, in the CU.

Get the voltage measured and what make are they, once did a job in a rural area where he lived next to the 11kv supply transformer, measured voltage was 251v, operating voltage of the lamps of the market was 220, they didn't last v long

Obviously poor quality cheap bulbs.

I must agree that was my first thought,never came across or heard of this happening before so as i said i'm going there later.
also asked here to check with next door see if they have had any problems.
cheers for the replys guys, have a great new year.

replace the bulbs with the halogen ones. save about 20% on running costs and they last forever. ( supply voltage being within limits )

Used to happen a lot with candle lamps as there's no room in the small envelope for an internal fuse such as in the standard gls lamp, hence the violent end. The girls in the lamp factory used to call the candle lamps " shooting stars". Merry Christmas. IIRC the tungsten evaporating from the filament used to cause a short circuit in the candle lamps and this with the lack of a fuse gave the dramatic finale. I think the candles were meant to operate bayonet down rather than bayonet up also - i.e. pointing toward the ceiling, I think this was a factor in the failure.

For anyone interested the fuses were called Ballotini fuses, google for further info.

Seeing a lot of this with the old fashioned ES spot reflectors plus trying to convince the customer the lamps are at fault

customer bought themselves some lamps n all a while back......
they didn`t last long either......
they were all 110V...lol....

to the O/P....could be a spot of overvoltage here.....test to verify...

All tested 238vac,changed all the lounge bulbs,thanks for the replys guys.
