The lights look okay and the prices are lower than average for comparable lights (in lumens). And the vendors are offering discounts. Might be worth a risk.

But I wouldn't pay attention to the many five star reviews on Amazon. Fakespot flags them as mostly fake, shills, etc., and gives the overall reviews a grade of F. Too bad because the lights may actually be okay, but the shill reviews lower the credibility of the seller and the product.
