Have the lamps now 1.5 years. Until now, I was very pleased with the lamps. Suddenly catches a flicker after the other !!! The lamps are ~ 3h am on day, ie up to today are the bulbs ~ 1650h in operation !!! Adequate ventilation was also available. In the wide lamps do not achieve the specified service life of min. 25,000 hours! Until now are already 5 defective from the 10 lamps, failure rate of 50% so far ...! This suggests that it is a poor-quality product.
This product can save any money in this short life. So let fingers of the product!
