well because they run at the same frequency as a magnetic ballast on a solid state pcb? what does this mean? it means that because of the high price of precious metals metals to maintain the higher currents of hid equipment. They skimp out and run lots of electricity through a circuit board thats made to support a cellphone. aluminum "polymer" basically metallic paint is used instead of gold, brass, or copper connectors as well as the internal capacitors not being manufactured in the US. That means instead of being filled with zinc oil they are filled with whatever liquid the chinese guy who made decided to put in it because of lack of standards. Thats why its shitty, and thats why its cheap. Failure rates are important, and I made the mistake of selling Chinese digital once and will never again.
