I bought mine from OK LED Light Bars
during a group buy
here. His customer service was excellent, he is based out of Moore, OK and this happened at the same time as the massive tornado that destroyed the town and he still managed to respond to questions in a reasonable amount of time. The description on his website should give you an idea about what you should be wondering. You probably don't want to be the guinea pig for a guy starting a new business venture buying a pallet of lights from china. There is usually a group buy going on for these if you wait, and make sure you use paypal or some other method where you can get a refund if you are unhappy with the delivered product.
