packaged finally arrived, but not sellers fault. as my postal office was slow, had to use AC220 to AC110 converter to make it work. but very bright and tested all of them and all good. recommend seller but anyone trying to take a gamble like i did to see if it will work on AC110, it will not. most of the stuff i bought saying requires AC220 worked for AC110.
When i place the order I had choose board with 10W leds that have 20 leds and the store send me 10W boards with 24 leds .If this is positive or negative at work then only the manufacturer must know.. Disadvantage is the receive time of order that is two days before the buyer protection time and exactly 60 days after i had place the order. More when I test it to real action.
