Meanwhile, every 4 purchased LED lamps broken and after only six months at an average burn time of 4 hours per day. That can not be true. If a time is not right, well; but all 4 that I had in the lamp are kaputtgegangen (the first after 5 months) within two months. That system. For the specified light output can be awarded only one star. I have a 1 Watt LED Lmpe who has many times more luminous against it here. Conclusion: Stay away, their money is not worth it.
