Query: Didn't work very long (if at all)

Had this light for 6 weeks before I decided that it was defective. Too late to return it and can't find a number for customer support. Bought two at the same time. First one wasn't very bright and would blink off and on by itself. I had been having some wifi problems with the 2.4g channel, so I thought that that was causing problems with the lamp. My ISP replaced the wifi router and I'm still having problems with the lamp. Today I plugged in the second lamp and it works without any problems and is much brighter. Dumb me - it took 6 weeks to figure out that the the first lamp was bad and now I'm stuck with it. The second lamp works well and I'm happy with it but since quality control and customer service is non-existent, I don't recommend this product.
