Received my Nichia variant two days ago and it has quickly become my go to edc. While the XPL has much greater output, the Nichia provided more than enough for my purposes and I use legitimate searchlights when I really need to reach out. Anyhow, this light has impressed enough to order two more for my camping setup. Time will tell if the reliability will be such that I will be willing to leave my backup non QTC Peak AAs at home. For now, the FW3A certainly has the potential to displace most of my 16340 and 18350 based alternatives due to the ability to pack an 18650 in such a small and infinitely variable light. I have an emisar D4, but could never warm to the side switch. This lumintop ticks the boxes for me. Tail switch, Floody enough to use as a work light, enough power to reach out when necessary, lots of juice, infinitely variable, and low enough cost that I am not afraid to abuse it.
