Astrolux, they don’t play.
My money on it that Astrolux will be both finished and ready for sale before the GT4 and will be more reliable than an Imalent as well.
No, it would be about the same. Similar diameter 44mm vs 46mm. Similar capacity. They probably went with 18650 so they don’t have to build new battery carriers and tubes.
I was just taking a long hard look at the photo of the guy with the light strung over his back and I said to myself…“OMG! What have I gotten myself into??”
