Oh wow. My mistake. I totally missed that. Thanks for the correction, I’ll edit.
Makes sense, of course a 5050 LED wouldn’t be nearly 7k lumens. Surprised that didn’t dawn on me, I guess I was tired lol, and y’know, it IS hard to keep track of all these new Chinese LED names!
But ok, so with the caveat that this chart isn’t super accurate, the SFN43 is apparently similar to an SFQ55 with a larger emitting area. The SFQ55 is what’s in the Nightwatch NS59V1, and those do ~2500-3050 at startup in that. So yea, 3500 lumens for the SFN43 seems right. According to the chart you might get a bit more but I know a single 18650 isn’t going to push 20A for long, if at all.
Still, very, very bright for a single domeless LED. If the tint is similar to SFQ55, then it should be quite good. Don’t know what CCT’s Wurkkos will use, but the SFQ55 in the Nightwatch was ~5700k, and very clean. I’d still be quite excited to see the SFN43 in this light.
Thanks SemiNormal for the correction and gchart for the review that I failed to read properly.
