Buy to replace halogen 50 installed by a pro, with 50,000 hours of life and having given soul after two years just to illuminate a carport. When installing the model purchased, the son being cut short, we had to open the back of the lamp and we realized that the earth wire was cut! My husband is handy and relatively low cost of the product, a fact that he repaired the system. Now he works in the hope longer than the last. I put a negative evaluation because of the risk associated with ground wire cut.
