Hi,
I had a look a job last week where numerous fittings had failed. I don't know how long they had been off, but I presumed they had all gone over time.
All the fittings (7x) were 55w PL type lamps with emergency backup. There didn't seem anything wrong with the ballasts. The store had a similar type fitting but 40w PL type (no emrgency backup) and none of them were out.
Is the life of fluorescents reduced by emergency backup?
Cheers
