Well I finally got my noctigons in from IO. I picked up a couple of the XPe triples for the new XP-L emitters.
I used a 5amp driver from Lightmalls, and optics from KD and put them together in a 502B host. To get the driver to fit I cut a slice of copper tube and then potted the driver into the slice of tube and the pill. On the other side of the pill I built up four 16mm aluminum stars and then some copper and the noctigon and then the optic on top of it. To get the optic to work correctly I de-domed the XP-L’s and filed down the legs on the optic lens to that it fit just a sliver above the emitters. I added another slice of copper around the sinkpad and noctigon that just barely fits. The heat transfer to the body is super.
With a Sony high amp 18650 I’m hitting just a hair over 1,600 lumens. It has a large hotspot and great flood. No rings and super nice tint. The driver is three modes. Low, Turbo and high.
With the optics too high you lose a ton of lumens coming out the side and the beam is kinda funky. When the optics set right over the emitters you get a nice round hotspot and more lumens.
