Do not understand the positive reviews. Light brings the specified output of 80 watts in any way. Bought have two lights for a basement room of about 25 square meters would have been then illuminated with 160 Watt. Actual performance equivalent to a maximum of 40 watts per light. My energy saving lamp that I wanted replaced with two 80 Watt were clearly much brighter.
In addition, the price is too expensive. Cover is cheaper plastic. Otherwise, the lamp is well made but worth a maximum of 30-40 euros.
I do not know why some LED luminaire manufacturers specify the performance coated high. Annoyed only customers!
