There is no problem with the product other than that the original fixture has these difficult-to-fit 'prongs' as connections. If attempting to fit to a kitchen with a tiled floor, use a folded towel under the light fixture.
Have previously bought these bulbs and they have been great and lasted well. This batch have been awful and have had to replace the new bulbs in under a month but some of the old ones still ok in the same light fitting.
I have a 4 light unit in the kitchen which is probably on for about 3 hours each day. I get through so many of these bulbs that it is really frustrating as some of them only last 2 or 3 weeks. They are not easy to fit either and I need to get the steps out every time one goes. Is there an alternative? I try to use low energy bulbs wherever possible but am seriously considering changing the whole unit to avoid having to use these bulbs.
