I purchased several hundred dollars worth of LED lamps and all are useless and some are damaged. I spoke to them for about 20 minutes at the trade fair, told them repeatedly I need 12 volt equipment and they supplied the wrong voltage equipment and went back on what they said. Asked for replacement fow two working lamps so they would work on 12 volt, they had the lamps for 7 months and did not replace them as promised. USELESS. Now I am $400 out of pocket.
