So to put a little incite to this. Kingsbrite, viparspectra, and bloomplus are made by the same manufacturer shenzhen lighting Co. Same diodes, same drivers, same warehouse. I would go with bloom plus. We could get into the 301b 301h argument but the difference is minor if any . The angles are the same. The price difference is even crazier. I'd stay with amazon because alibaba just looks like a sketchball site to me and I'm 2 weeks being generous from transition so speed of arrival is a factor .
shenzen is a super factory. 100’s of companies all building electronics in there. And there lies the problem. Counterfeiting is the specialty not selling authentic products. So what you are saying is not true at all. One could be fake and one could be real. And tomorrow they may reverse depending on parts availability. They have no patent laws and no scruples about branding.
