For me not really make sense as used with bulbs then too long for most lamps

Application:
I bought this adapter to lamps with E27 socket in lamps with E14 base to operate. However, I realized then quickly which then survive the bulbs very far or is to be seen in some glass of the bulb of the adapter even. Therefore, I have now no more of 4 adapters in use. But I have to point out that the dimensions are given, and this is not a defect in the product, I simply underestimated the dimensions.

Function:
The product is working properly and converts virtually form the basis. With several lamps tried the E27 bulbs glowed in the E14.

Processing:
The adapter feels like plastic / ceramic and are meticulously crafted. Especially when it comes to current and potential hazards such as fire I was doing no compromises. In this article, I had no doubts.

Price-Performance:
Bought the set costs an adapter about 2 euros. If you can use the adapter because of the design and you can be by having to purchase new bulbs saves about to pay off. Given the processing of the price in my opinion is appropriate.

Criticisms:
no.

Conclusion:
I would not buy the product again because it just is not nice looks at my lights but that does not mean yes, the adapter is not working. I forgive therefore 4 stars because the function is given and the item itself is clever. If you can use it in, for example, in ball-lamps can thus use much stronger bulbs and has more choice about LED lamps with more than 800 lumens it as not been on the market for E14.

But you should measure it precisely because even a few centimeters can differ depending on the lamp make a big difference with protruding bulbs it looks like fudged
