Clic to read the whole SC70 driver Analysis posted by thefreeman:

Here are the Cliff Notes:

"Conclusion

To improve this driver, Zebralight needs to:

* get rid of low modes visible flicker

* Get rid of the ~400~1000Hz Riple by increasing the PWM control signal frequency

* fix the low modes startup flash

* Fix instability issue in medium modes"

Well, none of this sounds good.
