"I have purchased over 100 of these lamps as I assumed they would be a good reliable product manufactured to a high standard. How wrong was I! I contacted the manufacturer who pointed me back to the supplier and weren't very interested. I now spend my time on a weekly basis having to return to clients to remove these lamps which have blown and return them for replacement to screwfix then go back and refit them. In one large project alone I purchased 76 of these lamps and within the first week 8 had stopped working. There are others that go off and on intermittently and when you remove the lamp and shake it gently they rattle in the base which I assume is the led driver or circuit. Over £2k spent and my clients are very disappointed with such an outlay and I'm now working for nothing as the manufacturer's technical department seem to have no interest. I would steer clear of this product in the future as a high price doesn't guarantee high quality.."
