My impression of the Sofirn SC31, almost right

Hello djozz,

Thank you for your summary of your impressions about this flashlight. I also considered this as a fairly good starting point to give muggles a reliable and good flashlight.

Let me ask a few questions:

  1. Did you test the battery charging with good (~10A) and poor (~120-200 mOhm IR, not above 2A) batteries. What was the voltage, when the flashlight just finished the charging?
  2. Can you confirm the LED MCPCB size of 16 mm?
  3. Is the head glued?
  4. Is the head compatible with any known Yajiamei TIR optics?

Another thing: in another Sofirn related topic, I suggested a slightly different UI for this flashlight to consider being implemented. Do you think, that it could be useful?
