Have the delivery received on time, despite the strikes on Amazon. Product met all my expectations, and I can extend the life not judge, so for now only 4 points. I Hatt often premature failures in LED lamps, so this limitation. I have therefore replaced the bulbs a hood (2x40W), where they do their job perfectly. Hope you are here just as durable as the conventional lamps, both of which were still intact after 12 years.
