FD battery flat out in 4days

[fitme]

forgot to turn off the celing light of my 10 months old FD...after 4days not using my car the battery was fully discharge, so i need my mates car to jump start my FD

my question is....is it possible that the 5watts ceiling light will consume my battery in 4days?? or my battery is dieying and needs to be replaced?

Batt shouldn't be dying. 4 days is long enough

i flattened the battery of a navara at work after leaving the parkers and hazards on for like an hour and a bit, then blew a fusible link on the positive battery terminal trying to jump start it to much. lol
