The title really tells the tale here. I took a lightly used blue mini mag, and cut it down to 1 AA length via the human lathe method, and hid the seam under the head. The head of the light was bored out to accept a 3/4 inch aluminum heatsink.
I reflowed three nichia 219 92 CRI emitters off a Kaidomain triple board onto a triple XP noctigon MCPCB and drove it with a BLF17DD regulated by N lite firmware set for 4 mode (no disco), ascending modes, and no memory. This light always starts on low. The low mode was supposed to be a moonlight low but is more like a good low mode.
The optic is a carclo 10511 narrow frosted triple. This light draws 5.3 amps for a brief period on high off an Efest IMR 14500. The KD nichia 219 graphs by Djozz suggest an output of 1100 lumens at startup. The head gets too hot to hold in about three minutes On to the photos.
The pics below are not of the actual pill but shows the build process and some of the materials.

First reply with "I'll take it" followed by PM gets the light.
