I've had my Zebralight SC600 for 3 months now. About a second after a cold start to turbo, it flickers for 1/5 a second and resumes as normal. Using AW 3100. Anyone else experiencing this? What could it be?
The moment you tap the on button, the light goes into your preset low mode, and if you didn't hold it long enough it pauses and jumps from low to high mode. That's what causes the flicker. The delay on mine is about half a second or so.
Mine does the same thing, the flash is the light going into low mode before turbo mode. This is perfectly normal for the UI that the light uses. As soon as you press the button the light is thinking "long press" so it comes on in the lowest mode. After the release it goes into turbo mode, I hope that made sense.
Normal operation of the Zebralight UI.
