I ordered an led t4 tube replacement. It took a few days to arrive and when it did the packaging was good but the tube housing was dented. It must’ve been dented before it went into the packaging as it was very secure in bubble wrap and a cardboard tube, which was unmarked on the outside. I was busy with work and by the time I came to fit it, it was well out of its return window, and unsurprisingly it didn’t work. Not sure why it didn’t work but the dent is evidence of a previous shock to the housing. Had high hopes for these as few seem to stock them and if it had worked I’d have bought 3 more for the kitchen.
