I had similar problem with my pos Mars reflector series. What you see is most likely lens got burnt and smoked, but led is fine. I had to just break off that shitty lenses to expose the led. I still use them for early veg, but considering to throw them away at this point... Only blurpurple that I really like is Hans Panel, but its way to expensive at this point with COBs and SMD's available for much cheaper.
