The Osram Dulux ESL 11W I have acquired as a replacement lamp for my desk lamp. Delivery was very quick what one is accustomed to Amazon. Goods arrived packed well with me. After changing the lamp, I was a little disappointed at first because of the supposedly weaker light. But it turned out that the lamp produces a warmer light than the previous one, thus appears weaker. The warmer light is more gentle on the eyes to my mind. All in all a good choice. Highly recommended.
