I ordered 40 GU10 7 bulbs which were delivered as agreed. these were for a large rewiring project in the living area of a barn. they were fitted over the next month. As soon as the lights started to be used the bulbs began failing. initially I replaced with spares. then called the company who said that they had had a batch with aprrox 50% failure rate, the later denied saying this. they sent a returns label and replaced the 9 failed bulbs and provided a few spares. the bulbs continued to fail and I was forced to insist on replacement and a return label which they were unwilling initially to provide. the bulbs continue to fail and most recently 1 of 4 bulbs in a double height vault. this cannot be replaced without a scaffold tower. the lights are stated to have a life of 15,000 hours and they are failing in less than 100 hours. the company has said I must return the bulb before it is replaced. they will not offer a return label. They suggest I can purchase more bulbs before sending back the faulty items. they have aid that the returned faulty bulbs will be examined for faults but they are unable to give any information concerning this. The product is useless and the returns policy a nonsense. do not buy from them.
