Looking for an adapter from E14 to E27 thread I have to decide with this adapter especially for a more expensive and good valued product - I wanted to buy a "scrap". When screwing a Philips Hue LED lamp it came however to a short circuit - the fuse was thrown out and the base of the lamp was charred. The LED lamp had previously works fine in other versions. As for the security of this adapter I have a bad feeling more. Months ago 2 1/2 I posted version and LED lamp on the merchant. Since then I wait in vain for a proposal on how the matter can be clarified.
