Flashy Mike, how did (or is) you sphere calibration lights work out? I posted similar questions here, and I know I remember reading responses to my answers but I can’t find them right now (perhaps in another thread?). I remember being told to go with an XP-G2 due to it’s higher vF which I have done. I have a Convoy M1 XP-G2 with a 6x7135 Nanjg driver custom flashed with STAR firmware to modes of 5–33–100% for this purpose (I generally don’t hold “high” mode). I then did a “recalibration of my sphere” borrowing the original Fenix HL-55 headlamp I used again and this time took measurements of many lights with nanjg “current regulated” drivers being sure to use fully charged cells.
I’ve had quite a few measurement sessions now since then and for now in addition to using my “sphere calibration check light” (i.e. the M1 XP-G2) I also measure at least some of those same nanjg driver lights. What I am seeing in actual use is that my XM-L2 lights (Convoy M1, 3.04A driver 8x7135 custom flashed to 2-modes, 35–100, and my mule headlamp with stock 1.4A 3-mode nanjg driver) are steadier and more consistent than the XP-G2. Even the M1 XM-L2 @ 3.04A is surprisingly steady. Overall I’m seeing some decent consistency between calculated lumens on these same lights from session to session.
Just curious how yours turned out.
