Another CNQ zoomy host, http://www.cnqualitygoods.com/goods.php?id=1957, “Registered User：$12.8”. Since the last one CNQualityGoods Zooming 1x18650 generic host (No longer available) and the Ahorton aspheric lens turned out so well, and I already have a second Ahorton aspheric lens http://www.illumn.com/ahorton-27-2mm-aspheric-glass-lens.html, $6.99 plus shipping, I got this one.
Looking at the first one with moonlight mode, the bezel ring cuts off the flood. So I plan to file it rounded in front when I file the opening bigger for the larger active area of the lens. Various alternative methods would work to enlarge the bezel ring opening, such as a lathe and sand paper wrapped around a dowel. I think I could do it with my pocket knife.
This is the best built zoomy that I have. I have one or two reflector lights that might compare with it. Heat transfer is unusually good for a zoomy. I may build a BLF 17 DD driver for it.
