Interesting. I purchased mine and separately purchased the ZWB2 filter. To be honest, I forget who I bought the filters from. Might have been gearbest or banggood. Not sure. I’ll check later. That said, mine has minimal visible light.
Forgot to mention, I bought the Convoy a couple of years ago from the official Convoy store.
It’s fasttech black S2 (not S2+) with LG LED. According to djozz test, they do generate a lot of visible light, but that light should be filtered-out by the lens. Apparently it’s not, it’s still daylight and the beam is bright blue. I see that in the dark I could easily walk around with nothing but that blue light.
Hm, apparently something is serious wrong. I have bought an LG-led from Simon (Convoy), and put that and a 40mm ZWB2 lens I got from djozz in a C8. And frankly, I would not dare walking off the road in the dark. The only thing I see is a vague hotspot, and occasionally something that violently reflects UV light. It almost looks like you got a 395-400nm UV light or a 450-455 nm blue light. But FT does not sell those!!
BTW the S2 I mentioned was the S2 3535 UV LED 1050mA 3-mode Grey I bought some years ago from FT.
A week ago I got the Astrolux MF02. I didn’t expect it to be that big and heavy. I always thought my Convoy L6 was big. Definitely not a light to carry around for more than one hour.
