I'm really surprised by this product. After I have often read like dark should be LED lights, here the complete opposite. The parts are incredibly light! In my opinion, this can easily keep up with halogen! Instead of the built-in 12 also 2-3, the radiator would have been sufficient for our hallway. However, the illustration of bulbs is not the product, but what I knew. The bulb has 3 LED bulbs inside. But it looks quite chic! I can say nothing about the life. Get this supplement here but once the first has failed. Important me the seller KHL should be mentioned. Just great customer service! I was advised by telephone top! I think even if still have problems with the product is also helpful on the part of the seller! Very strong buy recommendation!
