Hehe, thanks guys!
Stretch is a special mode, selectable on the
programming page. When off, the light runs in full regulation until the battery is exhausted (2.8v). With stretch turned on, the light runs in full regulation until 3.2v. At 3.2v, it starts to dim in slow 1/33 steps until the battery is exhausted (2.8). These are the same gradual steps used in our thermal regulation system. In practice, you:
- give up a few minutes of runtime at full power
- gain a bunch of minutes safety power, so you're not left in the dark
- have the chance to recharge the battery sooner, so it wears less
In practice, its like having a hybrid regulated + direct drive light, with just the right amount of controlled DD dim just when you need it at the end.
