I'd like a really long runtime (1+ hour) 9V SF Turbohead lamp assembly for 2x li-ion cells (I know the MN15 runs for 2.5 hours in the M6, but it takes 6xCR123 for that..)
The MN15 is still a good choice for that.....
From mdocod's data;
Cell configuration: 2x18650

SF MN15: 10W, 154 - 103 lumen in 104 minutes

SF MN21: 37W, 600 - 375 lumen in 15-20 minutes (unprotected cells required, dangerous configuration)
