I am the source, and the Island is hardly typical of a UK conurbation so will need dealing with differently. don't forget the good old Manx Winters, Tesco have experience of this and will change the local model to suit.
my old bulb went pop recently so I replaced it with a halogen bulb, same shape, wattage etc, seems to work just fine. definitely gets warm enough to get the wax flowing.
estimated delivery dates seem to be back on track, 2/3 day delivery 🙂 check your delivery address, if it includes United Kingdom rather than Isle of Man then that puts it back a week.
