These mains LED's seemed very good at first - nice spread of light and not too bad a colour, just a bit dimmer than the 50w halogen they replaced. BUT - now they are starting to fail. 2 so far, out of 10, in just a few months. Advertised to do 50,000 hrs, these have done 1000 at the most. At around £5 a go, all the savings in electric consumption are beginning to disappear. NOT good !
