gu10 mains lamp blowing

[james king]

hi all i have changed 6x gu10 downlights in a kithchen as the down lights befor kept blowing there were LV.

what may cause the lamps to blow regualy eg only 3-4 hours of being on? all suggestions would be grat

Are you sure they are only lasting a few hours?...customers often say they have only lasted a short time when in reality they have got mixed up with what has been replaced. A loose connection serious to cause lamp failure would almost certainly produce noticable flickering.
I would still suggest it is lamps..(see robsparkys post)....try a different batch of a quality brand and get the customer to keep a plan of which lamps blow and when.

Wrong polarity....the N and L are reversed......needs rectifying but wont affect lamp life.

Jiga. Alright? Did you get this resolved? If so what was the result please.
