Hi All,
Earlyer this year I installed x 20 downlights and in order to save customer a small fortune in electricity bills have fitted LED lamps.
These lamps were installed stating 11,000 hours life (approx). Looked good and customer happy.
However, we are now 10 months down the line and to date I have had to go back and exchange x 8 of the lamps which have blown.
All have not blown at the same time, following the first couple of months problem free we now have one (different fitting each time) blowing approx every 3 to 4 weeks.
Given the level of failures the supplier has agreed to refund the lot but is not convinced the lamps were faulty and suspects surges or inconsistent supply in the circuitry.
Can anyone shed any light on possible causes and ofcourse any possible soloutions.
Totaly baff-led
