Call the store. Most retailers will offer a store credit without a receipt.
Made in china???Called them today and explained the situation. The guy said they could give me an even exchange with no receipt, but if I just wanted to return it I'd need one. I told him the exchange would be fine. Of course they have every color but amber so he said he'd hold the color of my choice for me until tomorrow. I took the defective one and removed the lens cover on it. Plugged it in again and it works fine! WTF. Put the lens cover back on and tightened it down but noticed if I tighten it too much it won't work. I loosened up the one screw and it's fine. I'm not sure but its working now and at least its the color I want so guess I'll keep it and call them tomorrow and let them know what happened.
