Well, much better with that 219B. (They state xpl but xpl does not have that fugly corona, so definitely XPL2)
Make sure to change resistors in the tailcap, it has a high parasitic drain, i measure it 3,5 mA.
The Ti Tool 2.0 has leds under the switchboot, they only work on LiIon. I dont have 14500, so I dont know if those indicator lights are in the Cu Tool AA… I dont think there is parasitic on the TiTool on AA, when the LEDs are not lit
compare and contrast, both lights weight the same, Rotary has 18350, aspect ratio 3.5 to 1 (light length divided by diameter), the Tool has AA Eneloop, aspect ratio 5 to 1.
improved the beam by removing the centering ring (1mm thick between reflector and mcpcb)
played with my calipers:
the XPL was 0.7mm taller than the sw45k I installed
work in progress
I used a single layer of Kaptan tape between reflector and mcpcb, 0.1 mm… may add 0.2mm later
considering lifting the mcpcb by 1mm… to regain original reflector pressure
atm the O ring at the glass is less compressed than when the 1mm centering ring is in the assembly, though I feel no play when pressing on the glass…
I would like to think the pressure on the thermal paste under the mcpcb is still adequate, at least on Eneloop… since I dont use 14500
the good news is that removing the centering ring gives a big improvement:
the ring of saturn around the hotspot is now gone!
