I wonder if any Olight owners can clarify something about their specs.

Take the i5t for example:

  • Level 1: 300-150-30 lumens, 3+25+122 minutes.
  • Level 2: 15 lumens, 20 hours.

Those measurements for Level 1, does the torch abruptly step down to the next luminosity, or are those readings more like samplings of a smooth discharge curve?

Thanks

Expanding a bit from what you asked, you'll find lights with the following behaviors with regard to battery voltage:

  • Output is the same in all modes regardless of battery voltage
  • Output is limited by battery voltage in maximum or near-maximum modes, but unaffected in other modes
  • Output is proportional to battery voltage in all modes

And when the battery gets low, you might see any of the following

  • The light turns off from full brightness
  • Brightness is reduced suddenly providing a low-output reserve mode
  • Brightness decreases as the battery nears empty, shutting off when a limit is reached
  • Brightness decreases as the battery nears empty, but does not intentionally shut off, which can damage Li-ion batteries
