Contact through Alibaba was good. They claim the lamp was ip68, but I did not use it for that intention, due to the very thin aluminum cooling ribs on the back of lamp. I believe they will corode quite fast. But the exact same cooling ribs keeps the lamp temperture below 60c', witch I believe will help on the lifetime on the lamp. The light spread is quite good and the lumens it produce are very good compared to the existing lamps. For info I bought the 200w. Transportation was quite rough but only cosmetics damaged. They could not be sold in a store.
Risposta del fornitore:
Thank you for your support and kindly feedback. And thank you very much for your satisfaction with the brightness of our products! Because it was shipped from China to Denmark using international express transportation and moving around too many places, the outer packaging were damaged. We are deeply sorry! We will give you a 5% discount on this subsequent order as an apology.
