Question about Olight specs (lemmy.sdf.org)

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
