A few years ago, Illumn ran a giveaway on r/flashlight. I unexpectedly won! It was a Tool AA 2.0 copper with SST-20 4000K. I liked the light a lot, but of course a year or so later, 519As came out. I recently started modding thanks to @stavigoodbye@lemmy.world and GetKong’s reddit posts and ordered some 519As from Simon. I decided the Tool AA would be an excellent first candidate. Came out great! Thank you so much, folks!
