So, in order: 1-the order was closed, and the goods have not yet been delivered (had to open a dispute for a full refund after closing the order... Aliexpress gave 10 days for delivery, because. The goods were already on the territory of our country... As a result, for 10 days he came...). 2-aluminum on lamps does not even smell!!! The whole body is made of plastic and even without a vent. Holes (probably 6 w of power cooling is not necessary!!!) in the end, even when checking the performance in 30 seconds-the lamps heated degrees to 50!!! Product do not recommend to buy!!
