Digitally Regulated Flashlights

[endetta]

Is it true that Digitally Regulated LED flashlights (and in my case Fenix L1d) in specific maintain its brightness level (dosent dim) to the point that battery can no longer provide sufficient power for that certain level of brightness and at that point they turn off insted of being less bright?
A FACT???? or ....:huh:

Yep, that's basically what regulated means... more or less. Some driver circuits are better than others at doing this. Some drivers can only regulate on certain kinds of batteries, and not other types. Some flashlights will drop out of regulation once the battery is too low, and enter into a "moonlight" direct drive mode.

Hope this helps.

This depends on the light, some lights change to a lower brightness mode other maintain regulation until they shut down.
A special case is protected LiIon batteries, because here the batteries shut down, not the light. Again some lights are designed to step down brightness, before the batteries shut down, others don't.

Very few lights shut off completely, and even then, usually only when running on Li-Ion rechargeables.

There are lots of good reviews here on CPF, and if you look for ones that mention "runtimes" you will find lots of detailed information like the graphs in this Nitecore review:
