The manufacture of these LEDs were incorrect in stating the drivers were not bad. As we had to purchase new drivers from a USA manufacture. The new drivers were installed and the LED lights do work now. We had sent the LED manufacture pictures of us testing their drivers and as proof yes their drivers were bad. This manufacture created a false statement only because they did not want to warranty new drivers. Yes we see this very often from China manufactures of not wanting to warranty their product. | Pudding is in the proof as they say. They ignored the proof by us testing them with a voltage meter. We had also sent this manufacture the invoice from us buying new drivers. All I have to say is, be very careful in who you do business with. This manufacture was placed on our DO NOT BUY LIST! | CEO | Kim Diemer | CZ ENERGY SOLUTIONS INC.
